Re: [Paraview] [EXTERNAL] Re: Make animation from steady state result

[Andrew Parker via ParaView]

Cory,

As a follow up.  Can I ask if it would be possible to do all that is
suggested on Scott's page:
https://www.paraview.org/Wiki/Advanced_Tips_and_Tricks#
Animating_a_static_vector_field

Along with all of your additional steps below from your last post (be great
to add these to Scott's page), entirely in pvpython or pvbatch?  I make use
of the anaconda version from here: https://anaconda.org/conda-forge/paraview

Would it be possible do you think to script all of this? I have not tired
it yet I should add just checking for show stoppers before I begin.
Thanks,
Andy

[Paraview] Fwd: Integrate Variables Over a Volume

[Andrew]

[Sorry, I forgot to change the mail address to Paraview. So copying it to
the list.]

Hello. I use ParaView 5.4.1 and I checked Integrate Variables on volume
now. It works but, as in some other cases in ParaView, it requires the
single entities type. For example, if you have a domain (volume) and
boundaries (surfaces), it will not work on you whole input. Use Extract
Block to extract the "real" volume prior the Integrate Variables.
There is the other thing that is not very good concerning this "entity type
problem". If you use the Calculator filter on mixed entities (fluid domain
+ boundaries) it says that it cannot find a variable, although it shows
this variable in it's drop-down list. It's confusing if you encounter this
the first time or have forgotten about this issue. May be it would be
better to introduce some sort of message to inform a user that there is a
"mixed entity issue".

Re: [Paraview] Integrate Variables

[Andrew]

Hello. The Intergate Variables filter just calculate the area integral of
each variable. If you need the mass flow then your workflow is correct. I
use the same approach:
1. Slice + coordinate thresholds if it's needed to bound the sloce.
2. Calculator filter with the function like
MassFlux=Density*VelocityVector*SurfaceNormalVector
3. Intergate Variables. The MassFlux integral is what we need.
Regarding the time dependence I cannot suggest you something because I
didn't work with transient cases in ParaView (I use CFD Post for
transients).
I also don't know the simple way to filter just one variable to integrate.
If you have lots of variables like in CFD results it's very inconvenient to
dig through all variables in Intagrate results.

[Paraview] Integrate Variables

[Andrew Roberts]

Hello,

I have a function for mass flowrate that I want to plot over a time period
DT. The velocity is time averaged per timestep dt, not the whole time
period, DT. In otherwords the number of timesteps is DT/dt.

mdot(T) = int_A (rho . u(T) . n . alpha(T)) dA

mdot(T) is the massflow rate over time (kg/s)
int_A () dA is the integral over the area of a slice through the domain
(m^2)
rho is the density of the particle phase and this is constant (kg/m^3)
u(T) is the time averaged velocity of the particle phase for a timestep of
dt and varies with time, T (m/s)
n is the unit vector normal to the area (-)
alpha is the time averaged volume fraction of the particle phase and also
varies with time T (-)

I think I am pretty sure that I can compute rho . u . n . alpha

My process in paraview:

Slice > Origin = 0, 0, 0, Normal = 0, 1, 0, Slice Type = Plane

This is the part in the brackets of the massflow rate equation. Mean just
means time averaged:

Calculator > abs(U1Mean_Y)*2900*alpha1Mean

Now I must integrate this over the area of the slice.

*** Is it correct to use the Filter > IntegrateVariables? ***

I then use PlotSelectionOverTime (which I'm pretty sure is right).

Kind regards,

Andrew

Re: [Paraview] [EXTERNAL] Re: Make animation from steady state result

[Andrew Parker via ParaView]

Dear all,

Sorry to post onto an old thread. I have been reading this thread and the
related write up here:
https://www.paraview.org/Wiki/Advanced_Tips_and_Tricks#Animating_a_static_vector_field

This thread (and the tips and tricks post) is really close to what I want
to do, but I have a few follow-up questions.  I too have a steady-state
solution field. I want to trace particles from the inlet of my domain to
the exit, following the steady-state velocity field, and report for each
particle the temperature-time history (or any other scalar from my
simulation) that the particle sees.  In additional and crucially, the time
the particle has within the domain: a residence time.  The residence time
would be the maximum value or IntegrationTime each particle attains before
it leaves the domain.

I see that if I follow the notes I can plot (using Glyphs) the temperature
as it varies across my domain as the particles are animated down the
streamlines: this is working.  What I do not seem to be able to find
however, is the IntegrationTime.  It appears as point-field data after the
streamlines are created, but vanishes after the contour filter is applied.
I guess the contour filter is computing a singular value for all values of
the IntegrationTime from T=0 to T=N with a specific level of granularity.
However, I can't seem to extract the specific value of IntegrationTime (the
contour value) when I stop the simulation at any given point.  Do you know
how to do that?  The "time" scale in the VCR window always goes from 0->1
not from 0->(max value of IntegrationTime in seconds).  Can the actual
value of time be backed out or animated? If so how do I do that, or am I
applying the Contour filter wrongly: as per the post, I am only using the
default values in the Counter filter panel.

Finally, and importantly for me, while the Glyphs move across the screen
following the streamlines, and render via the temperature field, how to I
actually extract information from this pseudo time series to perform
analysis?  For example, the min and max temperature seen by a particle as
it moved across the streamline for instance?  I'm actually hoping to plot
offline (as a function of IntegrationTime) the min and max temperature
obtained for each particle: I can then take the min and max of that set for
the quickest and slowest particles.

Using the latest stock version of paraview.

Cheers,
Andy

Re: [Paraview] Integrate variable filter

[Andrew]

Hello.
For calculationg volumes and areas, the "Cell Data" attribute type of
Integrate variables filter is usable. You don't need to define additional
constant field for this. I checked it now and it seems to give the correct
domain volume (554 m3 in SolidWorks, 557 m3 in ParaView). The error may be
due to unequality of mesh and "ideal" geometry. You can also use the
Threshold filter before the Intergate variables to define the custom volume
(with particular scalar values).

Re: [Paraview] Equally spaced points on a slice (for the streamlines)

[Andrew]

Hello, Kenichiro Yoshimi, and thanks for your help.
I tried the Smooth filter just now. It works, but it seems to be not
appropriate with very irregular point distributions. Things look only a bit
better with it.
I also tried this filter after Mask Points with Random sampling +
Randomized ID strides that generates more even distribution than initial
seed. But the Smooth filter tells that, in this case, it has "nothing to
smooth".
Mask points filter works being applied after the Smooth (with default 20
iterations) but it's not better than just Mask Point on initial slice with
Random Sampling + Randomized ID strides.
The way that look simple is just to create glyphs with Uniform spatial
distribution option and to apply the Streamlines to these glyphs as source
points. But here is an another "snake in the grass": although there is an
appropriate number of glyphs when I visualize them, the Streamline filter
tries to draw lines from every point of initial slice, not from "glyphed"
points.
So I still stay with Mask Points + Random sampling + Randomized ID strides.

Re: [Paraview] Equally spaced points on a slice (for the streamlines)

[Andrew]

Hello.
Sorry for being so slow, got lots of work with reports...
Just tried Mandelbrot filter applied to a slice. With defaults, it created
a kind of fractal rotated and translated relative to original slice. Should
I use some particular settings to just resample? Also, tried Wavelet and
Gaussian resample. These filters create volumes being appliet to the slice
so it seems that they doesnt fit my needs. Any suggestions? Is there some
simple filter to resample arbitrary surface in ParaView.
Thanks for your attention. (Now I use Mask Points with the same problem of
un-even point distribution, the best results are with Random sampling +
randomised ID strides, but without limiting the maximum number of points;
instead of this limit I preview points with glyphs and then feed these
point to the Stream tracer with custom source)

Re: [Paraview] cutting unstructructured grid data with a plane

[Paraview] Equally spaced points on a slice (for the streamlines)

[Andrew]

Hello.
I need to distribute points on a slice equally to start streamlines from
these points. The problem is that the Mask Points filter seems to not to
have such option. I tried all combinations of randomizing in this filter
but the problem persist. My mesh is unstructured tetra with inflation
layers on wall so there are lots of cells (points) at the wall and almost
all streamlines start in near-wall region while I need their starting
points to be equally distributed along the slice. Is there a way to do it
in ParaView?

[Paraview] Silhouette filter

[Andrew]

Hello.
Some time ago I used the Silhouette filter for ParaView to visualize
geometry edges (not mesh but indeed *geometry* edges). But I've missed the
file and cannot find it for download now... Would, somebody, please, share
this filter or give the download link? As some other people do, I use
ParaView 5.2 as a most recent version compatible with RDP (I don't know if
it's important for the filter compatibility).
Thanks.

Re: [Paraview] Select points based on coordinates

Hello.
Possibly the Threshold filter is what you looking for (if you need to
select a number of points in specified coordinates range). You can use 2-3
filters in series to shape the region in 3 cartesian directions.

Re: [Paraview] Removing wire frame from Ensight Gold Case Data format

[Andrew]

Hello, Niaz. Sorry for being late. I usually process such features in CFD
Post. If there is a long-time task (creating an analytical report) than I
do most visual processing in ParaView and some things that a too
non-convenient in ParaView I do in CFD Post. Fast processing like checking
current simulation state is usually done in CFD Post.
Possibly there are special types of curved slices in ParaView, I don't
know... What is great in CFD Post that it perfectly understands boundaries
including mass fluxes "from the box" for both CFX and Fluent (in ParaView I
use a simple Python script to do it, and I need to tweak this script every
time variable names change).

[Paraview] solid white surface (with edges) in 3D via UI + large vector graphic pdfs

[Andrew McRae]

Hi all,

I think I am trying to do the same thing as http://public.kitware.com/
pipermail/paraview/2015-July/034441.html from two years ago: show a solid
white 3D mesh, with black lines marking the cell edges, on a white
background.

I finally got what I wanted by following Cory's instructions in that
thread, using the Python scripting window.  *I can't seem to find a way to
do this through the GUI options though... am I missing something?*

Using a black wireframe on a white background almost does what I want, but
I don't want the back of the mesh showing through the image... (it's a
non-uniform mesh of the sphere, so seeing the back cells becomes
confusing).  vtu file, in case anyone is interested:
https://www.dropbox.com/s/y3euop4nzurf9gf/ri-cs_0.vtu?dl=1

*Also, why are the generated vector images so large?*  (Export Scene, turn
off rasterization)  The pdf produced by ParaView for the above vtu (no
data, just the mesh, viewed from +Y) is over 2MB for a mesh with 6146
vertices, 6144 cells.  At first I thought this was due to shading, but it
has persisted even when making the cells fully white.

Somehow, outputting as a .eps file (~1MB) and running epspdf on this
generates a ~200KB .pdf, which is much more reasonable:
https://www.dropbox.com/s/njavup5vwubsq8p/ri-cs.pdf?dl=1

This is all with ParaView 5.0.1.  At various times I tried downloading
Paraview 5.3-5.4, but there was no improvement in this area (and, IIRC,
some regressions, such as glitchy pdfs).

Thanks,
Andrew

Re: [Paraview] Removing wire frame from Ensight Gold Case Data format

[Andrew]

Hello.
Yes, there is a problem that exported CGNS doesnt consist BCs. So I create
slices at appropriate positions limiting their span with Threshold filter
by coordiates if needed. Another problem with BCs is that even if you have
surfaces there may be very limited variables so you cannot average by mass
flow that is absolutely unaccaptable. With slices you have all variables
that are difined in fluid domain. More suitable and simple way is using CFD
Post but it will consume a license. So I often postprocess "visual
features" in ParaView and use CFD Post's Function Calculator for averaging,
mass flow calculation on boundaries e.t.c. To my knowledge, there is no
such functionality in ParaView (various types of averaging, convenient BC
support, convenient multi-variant support, for example, if you need to open
3 separate cases and compute 10 quantities for each case, CFD Post will be
one of best choices). But, apart from consuming a license, CFD Post is not
so "feature-loaded" as ParaView. There is no Python Shell and only basic
tools in CFD Post so use what is more appropriate for particular usecases.
The thing that is called post processor in Fluent cannot be described in
good words and easily can hang. Don't use it if you can. CFD Post and
ParaView compared to this thing in Fluent are unrealistic good!

Re: [Paraview] Removing wire frame from Ensight Gold Case Data format

[Andrew]

Hello, Niaz.
I also noticed the same problem in some cases with export from Fluent. I
suspect that Fluent write files incorrectly, as if every cell was a
separate domain. It explains why ParaView becomes very slow with such files
and why we cannot remove mesh lines from representation. Sorry, cannot
suggest something useful, because didn't remember details. Maybe exporting
in CGNS or changing export options will help. Or, maybe, providing a sample
dataset to ParaView developers will help them to identify the problem and
introduce some tweak/workaround in reader.

Actually, there are various problems with exporting from Fluent and CFX in
neutral formats. Apart from the bug you mentioned, ParaView (4.3, 5.0, 5.2
for Win64) cannot open CGNS files written by CFX 18.0 Solver Manager: there
are no variables in list (I tweaked export settings without effect). At the
same time, it reads successfully CGNS written by CFX 14.5 Solver Manager.

likely an RDP issue and don't hope that newer versions will work so just
use 5.2 on this machine.

Re: [Paraview] Unable to open .dat file in paraview

[Andrew]

Hello.
Anyway, ParaView has not full support for Fluent files (cas + dat). It
doesn't see all the variables (at least in versions up to 5.0.1 RC2 that I
use, although I know that I should update to 5.2 or 5.3). Instead of
reading Fluent format, I convert to EnSight (in Fluent) and then read in
ParaView.

Re: [Paraview] [Non-DoD Source] XDMF makes paraview crash with JOIN

[Burns, Andrew J CTR USARMY RDECOM ARL (US)]

In Xdmf3's reader, the assignment of variables occurs in 
XdmfArray::populateItem. The evaluation of the function occurs in XdmfFunction 
"|" denotes XdmfFunction::chunk (effectively concatenate). From there it should 
be a bunch of XdmfArray::insert calls.

Xdmf3's source in Paraview is under Paraview/VTK/ThirdParty/xdmf3.

Hi,

I have been looking closely into this problem in the past few days, and I have 
never been able to make the Xdmf3 reader to JOIN any HDF5 data. Neither with 
the JOIN() syntax nor with the "$0|$1" one. At least to populate an Attribute's 
DataItem. The Xdmf2 reader works until 10 elements are joined.

To go further in this investigation, could someone point me to the source code 
of the Xdmf3 reader, specifically where the "joining"
takes place?

Cheers
Fred

Re: [Paraview] [Non-DoD Source] XDMF makes paraview crash with JOIN

I think that is because Xdmf3 uses different syntax for concatenation. Try 
using Function="$0|$1|$2|$3|$4|$5|$6|$7|$8|$9" with the Xdmf3 reader.

Hi all,

I have successfully used the JOIN Function for the XDMF reader to concatenate 
the data from several HDF5 files.






0.0 0.0
0.3 0.06



mystuff.h5:/02/By
mystuff.h5:/07/By
mystuff.h5:/12/By
mystuff.h5:/17/By
mystuff.h5:/22/By
mystuff.h5:/27/By
mystuff.h5:/32/By
mystuff.h5:/37/By
mystuff.h5:/42/By
mystuff.h5:/47/By






However, this technique only works when joining a maximum of 10 different 
pieces of data. If I add one DataItem in the JOIN Function, ParaView crashes 
upon clicking "Apply".

Is there a reason for this? Am I doing something wrong? Is there a workaround?

Cheers
Fred

Re: [Paraview] [Non-DoD Source] XDMF crash

[Burns, Andrew J CTR USARMY RDECOM ARL (US)]

The load time is because Paraview needs a moment to load the data for the new 
timestep in. When you switch variables all the data is in memory already.

This is done because Paraview is designed to work with large datasets. For 
higher scale implementations it wouldn't be feasible to have all grids loaded 
in memory simultaneously.

I already tried XPath pointers, but it takes a few seconds in ParaView when I 
click to the next time frame --- whereas it takes only 0.1s to change the color 
when I switch the Active Variable for the ColorMap in ParaView's dropdown. 
I thought using SubSet, ParaView might "recognize" that it is actually all the 
same geometry. 
But meanwhile I assume ParaView always thinks the geometry might change between 
timeframes and takes much time for switching between timeframes no matter what 
file format I use.

From my understanding of your method, you want to use the progression 
of "time" to iterate across attribute displays?

You don't need GridType="Subset" for that (and I don't think Xdmf3 uses 
that designation anyway). Just use XPointers to point the grids to the topology 
and geometry of the first one.

Hello Mr. Burns, thank you very much for your helpful answer. I changed 
the XDMF file. But now I have another question.

Now I have problems with GridType="SubSet". ParaView doesn't view the 
second and third timestep. Their grids are referenced as SubSet from the first 
grid.

This is the reason why I am doing all this: I want ParaView change the 
color on a static, fixed, large geometry as quickly as if I switched the 
surface coloring variable in the Active Variables Controls dropdown, but using 
the time playback features. It is very inconvenient to change the "timestep" by 
selecting an other variable in a Color Map drop-down menu with thousands of 
entries. Is this even possible in ParaView?

Time item per grid is the preferred method.

I generated the following XDMF file and tried to open it in ParaView. When I 
open it, I get a dialog with three readers to choose: 
- XDMF reader
- XDMF3 reader
- XDMF3 reader (Top Level Partition)

I can open the file with "XDMF reader", but when I open it with the other two 
readers, ParaView (5.1.0 64-bit Mac) crashes. 

Application Specific Information:

Re: [Paraview] [Non-DoD Source] color mapping of XDMF and HDF5 file is not shown

[Burns, Andrew J CTR USARMY RDECOM ARL (US)]

Looked into this. There are two errors going on.

1: The type should be "Float" not "Double" Xdmf defines double as float with 
precision 8.

2: There is an order of operations error in the handling of the X_Y_Z type. 
We'll put a fix for it into the next Xdmf3 reader.

Hi,


I am woking with HDF5 and XDMF file to visualize in ParaView.

three problems are found in reading xdmf reader.

1) in MS Windows, color map is shown correctly but in Linux, color map is gone 
and nothing is shown but grid surface.

2) in Linux (not sure in Windows), Paraview 5.1.2 has problem in reading 
attribute data

3) xdmf3 reader cannot read my xdmf file. which part should I correct in order 
for xdmf3 reader working


Thanks in advance.

Re: [Paraview] Regarding filtering of point data array

Hello. Possibly Threshold filter will help you. To limit points by 3

Re: [Paraview] Volume Render Plot - Unreasonable results with vector components or magnitude

[Andrew]

Hello. I noticed the same behaviour in ParaView 4.3 on CentOS 6.7. Looks
like bug. Worked around with calculating the velocity magnitude as scalar.
There is also another bug or feature of volume rendering: I couldn't make
it render for all domains, it only renders one domain (for example, when I
load a CFD study results in EnSight Gold format).

Re: [Paraview] [Non-DoD Source] Questions about XMF - 3DCoRectMesh

[Burns, Andrew J CTR USARMY RDECOM ARL (US)]

Looking at the old error reports, it's an issue of differences in indexing in 
programming languages. I guess Paraview was initially designed with Fortran's 
output in mind?

Hi everbody,

I have a stupid question about the XMF - 3DCoRectMesh...

I tried to build an "extruded rectangle" using this function (I 
attached the files).

I asked for a 6 by 16 by 46 elements as you can see in the XMF 
file...

 
 
   
 -0.60
 -1.60
 -4.60

but when I open in Paraview (4.3.1 and 5.1.2) I found a 46 by 
16 by 6 elements...

I tried also to look in: 
VTK/ThirdParty/xdmf3/vtkxdmf3/XdmfRegularGrid.cpp, but I didn't found the 
reason to Paraview "change" the X axis by the Z axis.

Someone found the same thing? Or, where I made a mistake?

Re: [Paraview] in-plane vector field from 3D vector field

[Andrew]

AFAIK, ParaView has no capability of projecting vector on surfaces. That's
why you need to work around with Calculator every time you need to get a
vector projection. If your plane is not just a coordinate plane, you can
use Generate Surface Normals filter, but it doesn't work on all datasets
(in my case it doesn't work on Fluent data exported as EnSight Gold Binary,
it generates normals but then the Calculator only shows that Normals in
vector list, Applying leads to error message that the Normals vector
doesn't exits, so one in the listbox is, probably, a ghost or something
:)). I used this method (Generate normals + Calculator + Normals.Velocity)
extensively with EnSight Gold files exported from CFX and it worked good in
ParaView 4.3 (it was the actual version).

Re: [Paraview] Mass flow average

[Andrew]

Hello. AFAIK, there is no any elementary filter to do it. I usually create
a Density*Velocity and Density*Velocity*Scalar variables in Calculators and
then apply an Integrate variable filter.  It integrates by area so I get
Rho*W*dF and Rho*W*Scalar*dF integrals. Dividing second by first I get mass
flow average of Scalar. Velocity must be a normal to control surface
component.

Re: [Paraview] [Non-DoD Source] Loading xdmf files fails in Paraview

[Burns, Andrew J CTR USARMY RDECOM ARL (US)]

Content in Xdmf's context is the data that XdmfArray contains. In XML this is 
the data between the XML tags.

For the Array:
output.h5:Data6

The "Content" is "output.h5:Data6" which is then parsed into an HDF5 reference.

The term "Content" is a carryover from the XML parser that Xdmf uses.

Subject: [Non-DoD Source] [Paraview] Loading xdmf files fails in Paraview

I'm trying to use Paraview with xdmf files which I've generated in a python 
script (both the xml light data and the hdf5 heavy data). Initially I was 
working with Paraview-4.0.1 which I could install from apt and loaded the data 
fine. Recently I downloaded Paraview-5.0.1, which fails to load the xdmf file 
in a variety of ways. If I try to load the dataset with the Xdmf3 Reader, I get 
the following error:

'Content' not found in itemProperties in XdmfArray::populateItem
Qt has caught an exception thrown from an event handler. Throwing
exceptions from an event handler is not supported in Qt. You must
reimplement QApplication::notify() and catch all exceptions there.

terminate called after throwing an instance of 'XdmfError'
  what():  'Content' not found in itemProperties in XdmfArray::populateItem
Aborted (core dumped)


If I try to load with the Xdmf Reader, Paraview segfaults. I found the same set 
of problems with Paraview-4.4.1.


How do I correct the lack of content in the xdmfarry? What does that even mean? 
(I don't recall there being a content tag necessary in the xdmf specification). 
I can post the xml and hdf5 files if necessary.


I would file a bug, but the bug tracker isn't accepting new users at the moment.


thanks

Re: [Paraview] ParaView 5.0.0 for Windows x64 fails to open EnSight Gold files

[Andrew]

ParaView 5.0.1 RC2 for Win-64 has been tested with my big EnSight case. I
loaded case successfully and created slice and vectors (glyphs) on it, no
any issues occured. Great thanks for debugging!

Meanwhile, I noticed that the color bar behavior is not as good as it was
in version 4.3. The color bar doesn't adjusts automatically to round
numbers (like my boss like to see in my reports :)), although it uses
correct fonts (it's known that version 4.3 didn't enlarge color bar fonts
in many cases despite of user's choice). But it's not a bug and scale can
be adjusted by hand (it's done much more faster than in CFD Post that
slowly rebuilds contour on every change on number of ticks, ParaView does
it almost instantly). I read some discussions a bit and I suppose that the
current behavior of color vr is a "common choice".

Re: [Paraview] ParaView 5.0.0 for Windows x64 fails to open EnSight Gold files

[Andrew]

Hello.
I recieved an email about corrected ParaView-5.0.1 and decided to test the
latest available official release for Win64:
ParaView-5.0.1-RC1-Qt4-OpenGL2-Windows-64bit.zip
I tried the same big EnSight case and the same error appeared (stat
failed). Should be this release "patched" or it's not corrected yet and I
should wait for another version?
Thanks.

Re: [Paraview] ParaView 5.0.0 for Windows x64 fails to open EnSight Gold files

[Andrew]

Samuel, thanks for your experiment. File with size less than 2 GiB, of
course, can't expose this issue.
I read a bit more about stat() and it turned out that it should work as
64bit if FILE_OFFSET_BITS is set to 64. And it is set in other ParaView
sources but, IMHO, not in EnSight reader. Dear ParaView team, please, take
a look at this, I need to process my big case with Python script in
ParaView...

Re: [Paraview] ParaView 5.0.0 for Windows x64 fails to open EnSight Gold files

[Andrew]

Sorry for many posts, but, I think, I found something interesting (or I
just think so :)). I digged a *stat*() usage in ParaView at official GitHub
source repository. If I get it right, there are two types of this function:
*stat*() and *stat64*(). My only program that deals with large files is a
disk editor & NTFS data recovery for Windows (it's free and was made at
home), this program uses WinAPI, not C/C++ calls for file operations. So I
don't know much about fopen/fclose/stat/e.t.c. on large files. So we have
*stat* and *stat64* + corresponding data structures. We can see an example
in this source:
https://github.com/Kitware/VTK/blob/eae7f4446c867ee9d29b466676fa11282d56dafc/IO/LSDyna/private/LSDynaFamily.cxx
For 64-bit configurations this code uses *stat64()* and *stat64* structure.

But if we look at the problematic place in *EnSight reader* we will only
see the "usual" *stat*() that is, to my current knowledge, is 32 bit:
https://github.com/Kitware/VTK/blob/master/IO/EnSight/vtkEnSightGoldBinaryReader.cxx
(Please see lines 100 and 101)
May it be the cause of the subj? Sorry if I'm wrong, I'm not a professional
programmer.

Re: [Paraview] ParaView 5.0.0 for Windows x64 fails to open EnSight Gold files

[Andrew]

I took a look at the code. Te problematic fragment (line 114 in
vtkEnSightGoldBinaryReader) just checks the file's existance and opens it
in standard way. The problem occures in *stat*() function that is fed with
the full file name and the reference to structure to receive file params. I
tried to read the file from Python shell and the result is the same. I
guessed that the reason is an additional slash before the short file name
(see error message) but small files are processed OK so the only assumption
I can make is that the problem occures in the *stat*() itself on large (>
~2GiB) files due to some strange 32-bit relicts (although itshould work
perfectly in 64-bit builds).
Can anybody test the opening of large (3...4 GiB or more) EnSight Gold
binary files in ParaView 5.0.0 or 5.0.1? I cannot check any assumptions
because I only have Linux compilators set up and cannot do the
"hello-world"-like stat() test under Windows on a large file...

Re: [Paraview] ParaView 5.0.0 for Windows x64 fails to open EnSight Gold files

[Andrew]

Hello Samuel.

Sorry, but I can't undersatand how can the file fragmentation affect it's
readability and parsing. Even if the file has thousands of fragments and
"brain-damaging" :) runlist in many extended FILE records on NTFS
partition, your program, if it uses Win API, will see it like a solid file
(althougt there will be very low performance of sequental access). So there
should be no any faults on reading highly fragmented files.
I have checked out the "direct" reading of EnSight case from the cluster
via samba with ParaView 5.0.0 on Windows machine. The same error appears as
in my first message, although there are *different files and filesystems*.
I think the problem is not a fragmentation but a *file size*. Some
32-bit-like relicts or so in EnSight reader (it's just a guess, sorry if
I'm wrong). But my hypothesis does not asks the question why does the bug
affect only Windows versions... Maybe there are differences between
versions concerning data types. Do you have any >4 GB binary EnSight 6 or
Gold case to test? I can't (not allowed) to publish my case and it's also
big enough for upload (although theoretically I can do it from my home PC).

[Paraview] Paraview bug found in pvtu files containing polyhedrons

[Andrew Parker via ParaView]

Dear All,

I have recently been having problems reading pvtu files in paraview when those 
files contain arbitrary polyhedrons: this is from the output of a large scale 
code that runs in parallel via mpi.  To show the problem, I have written a very 
small sample code, attached, that runs in serial but reproduces the salient 
issues experienced by my larger code when run in parallel.  It is clear, via 
the toggling a boolean, that the problem happens when vtk_polyhedrons types are 
used.  There is a short description at the top of the bug.cxx file, followed by 
instructions.  I use stock versions of paraview here, although self compiled 
ones show no difference.

In short compile the code, run it, and open the pvtu file in paraview.  You 
should see 4 cells.
Switch the “bug” bool to true, recompile, re-run it, and reopen the pvtu file.  
The screen will be blank.  

The only difference is that cells are added to the unstructured grid explicitly 
as vtk_polyhedrons using a face-stream, rather than as hexs.  I cannot do this 
in the real code!  The rest of the code is just there to produce the “serial” 
mesh, and threshold this mesh to produce two “parallel-partition” meshes.  I 
use the new ghost type framework as this is consistent with the real code, and 
this runs and compiles on OS X and gcc.  Likewise it has been build against vtk 
6.3 and the bug manifests itself in paraview 4.4 and 5.0.  Visit 2.10 does not 
have this bug and can correctly open the pvtu containing polyhedrons: this is 
my current workaround.

Can any of the developers shed light on this?  Is a fix known, if so when will 
it be released?  Do others have this problem [1, 2, 3] outside of those long 
reported? Does anyone else have workarounds?

Any help really appreciated, 
Andy

Re: [Paraview] ParaView 5.0.0 for Windows x64 fails to open EnSight Gold files

[Andrew]

Another "experimental data". I was able to load this big case in ParaView
viat the CGNS format. It was neccesary to select CGNS 3.0 and HDF5 options
in CFX Converter. But when I apply the Extract Block filter I see no any
boundaries, only fluid domain (that is displayed OK). So CGNS format is not
a wayout...

I performed another test with *EnSight 6* (not Gold) format. Conversion was

Re: [Paraview] ParaView 5.0.0 for Windows x64 fails to open EnSight Gold files

[Andrew]

Hello. Sorry for silence, I'm usually offline on holydays, although I have
internet connection and read your mail.

Samuel Key

Thanks for your attention.

About transferring files from Linux to Windows. I use binary EnSight files
because CFX converter fails to write so large files in ASCII format. But I
tried to convert from CFX to EnSight (binary) on the same Win-7 x64 machine
with ParaView. Both installed versions (4.3 and 5.0) failed to open the
geometry (I unchecked all fields). ParaView 4.3 crashed, ParaView 5.0 just
cannot open file...

I think that the root cause may be a geometry file size. It is 4.9 GiB (5.3
GB), mesh have about 150 millions of cells, not 600 thusands like in your
case. Its possible that ParaView for Windows cannot process so large
EnSight files, although the Linux version reads in this geometry and
displays outline (swapping is so intensive so I cannot displaye something
else).

[Paraview] ParaView 5.0.0 for Windows x64 fails to open EnSight Gold files

[Andrew]

Hello. We use Ansys CFX in our work but the standard post-processor
CFD-Post consumes one of Ansys licenses while Paraview is free. So I often
make pictures for reports with ParaView to preserve Ansys license for
another users/needs (because other users are not familiar with ParaView and
CFD-Post may consume general "acfd" license feature that may be used for
calculations). I convert CFX results to EnSight Gold format in CFX Solver
Manager (Export Results) and then open in ParaView. It was working well on
Linux (CentOS 6.7 x64, Ubuntu 12.04 x64 with updates) but now I work with
large files and I need to use another machine that has 128 GB of RAM and
runs Windows-7 x64.
I downloaded and installed the following version:
ParaView-5.0.0-Qt4-OpenGL2-Windows-64bit.exe
When I open my EnSight-format file I receive the error message that
geometry file cannot be read. I tried to move EnSight files to a simple
location (D:\Temp) and renamed them (test.case, test.geom + edited the case
to change geometry file name to "simple" one). The same result, it cannot
find geometry file... Full error message is as follows:

ERROR: In

OK, I tried to open it in ParaView 4.3. It says nothing (only border of the
message window appears) and crashes. At that moment I see in the status bar
that EnSight reader progress is 100%.

Both ParaView 5.0.0 and 4.3 was tested with EnSight files exported on Linux
and Windows machine. It didn't help.

OK, I tried to export CFX results to CGNS format. ParaView 5.0.0 (without
MPI) cannot read it, so I fed it to ParaView 4.3. It says that its "unable
to filed any meshes".

I also performed an experiment on my Linux laptop. It has only 16 GB of RAM
so its unreal to work with such a big file on this machine but it reads the
same EnSight case and displays the domain! No arrays selected (mesh only),
swap file grows up to 8 GB but the file opens without errors and crashes.
It's only a test because I have not any Linux machine with memory large
enough (our Linux cluster has 128 GB of RAM on every node including master
but it has very poor video).

I switched to CFD Post for this case but I want to know are there any
workarounds to open my EnSight-format results in ParaView for Windows.

Thanks for your attention.

*vtkXdmfHeavyData::ReadUniformData(xdm**f2::XdmfGrid *, int): Assertion
`xmfGrid->IsUniform() && "Input must be a uniform xdmf grid."' failed.*

I dug through the backtrace, and it seems that
*vtkXdmfHeavyData::ReadData(XdmfGrid*
xmfGrid, int blockId)* is incorrectly forwarding the Subset grid to the
vtkXdmfHeavyData::ReadUniformData function.

Here's a self-contained XDMF file to test with:

  3 4 5
  6 7 8

  
  

  0. 0. 0.

  1. 0. 0.
  2. 0. 0.
  1. 1. 0.
  2. 0. 0.
  3. 0. 0.
  2. 1. 0.

  


  
0 2
  
  
/Xdmf/Domain/Grid[1]
  

  


I'm relatively confident that this should be a valid XDMF file, but I'm not
positive since I wrote this by hand and the documentation for subsets is
relatively sparse.

[Paraview] Building Paraview (QT) from source

[andrew solis]

Hey Guys,

 I'm trying to build Paraview from source on windows and ran into an
issue when trying to configure and qmake QT. I've been following the
directions at http://www.paraview.org/Wiki/ParaView:Build_And_Install and
downloaded "qt-everywhere-opensource-src-4.8.2.zip" and unzipped the files.
I opened up a 'Developer Command Prompt for VS2013' and navigated to the
unzipped folder that holds the qt source and typed configure, o for open
source version, and yes to accept the license offers, but then I get an
error when it tries to create qmake.

Creating qmake...
execute: File or path is not found (mingw32-make)
execute: File or path is not found (mingw32-make)
Cleaning qmake failed, return code -1

I thought that opening up the developer command prompt for VS2013 set all
the path variables so that mingw32-make wouldn't be needed, so this may not
be the case. Any help would be greatly appreciated.

Thanks!
Andrew Solis

[Paraview] Multi-tiled Distributed Display

[andrew solis]

Hey everyone,

 I'm trying to run Paraview using the vrpn plugin so that I can show
off Paraview on a distributed multi-tiled display, and I'm stuck on getting
it set up. The head machine is named stallion and there are 20 different
nodes that control 4 different screens horizontally that make up a 16x5
display. I'm trying to get Paraview to run on just one server machine as a
test and have been following the documentation on Immersiver Paraview found
at http://www.paraview.org/Wiki/Immersive_ParaView. I've set up my pvx file
to be like so:




  


  

  


  



where s01 is one of the machines I'm using to show off with FullScreen
declared so Paraview is shown on all four screens the server controls
horizontally. What I'm confused about now is probably stupid, but now that
I have my pvx set up I want to test and see if I can get it to show on my
display, but I'm not sure how. I'm also relatively new to using vrpn so I
didn't know if I needed to set up anything with that as well beyond
installing the vrpn plugin. Please feel free to let me know if I explained
something wrong or if I need to answer any other questions, and any help
will be greatly appreciated.

Thanks!

[Paraview] Warning: Target "VRPlugin" requests linking to directory

Hello,

 I'm relatively new to Paraview and I had a question concerning getting
Paraview to run on a Linux machine from source and adding vrpn. I
downloaded and built both I believe, and I am using ccmake to build it.
When I run ccmake and then try and generate however, I get an error at the
end stating:

WARNING: Target "VRPlugin" requests linking to directory
"/home/ajs2987/Projects/ParaviewOnStallion/vrpn-07.33-bin/lib".  Targets
may link only to libraries.  CMake is dropping the item.

Any particular reason why this would be happening or how to fix it? Any
help would be appreciated.

Re: [Paraview] Compiling ParaView 4.3.1 with OpenMPI

[Andrew]

Menno Deij - van Rijswijk,
Great thanks! Your suggestions worked perfectly! Now I have ParaView 4.3.1
compiled with MPI and Catalyst for co-processing.

2015-08-18 14:04 GMT+03:00 Deij-van Rijswijk, Menno m.d...@marin.nl:

 Hi Andrew,

 I checked my CMakeCache to see the variables of MPI and I think you need
 to change the MPI_LIBRARY:FILEPATH to
 MPI_LIBRARY:FILEPATH=/Programs/openmpi-1.8.4/build/lib/libmpi_cxx.so

 That is, directly use the full path to the mpi shared library, instead of
 using the link flag.
 Also, change the other LIBRARIES variables. In my case there are multiple
 libraries:

 MPI_C_LIBRARIES:STRING=pathlibmpi.so
 MPI_CXX_LIBRARIES:STRING=pathlibmpi_cxx.so;pathlibmpi.so

 MPI_Fortran_LIBRARIES:STRING=pathlibmpi_usempif08.so;pathlibmpi_usempi_ignore_tkr.so;pathlibmpi_mpifh.so;pathlibmpi.so

 Where path should expand to your install path, which is
 /Programs/openmpi-1.8.4/build/lib/

 Good luck and best wishes,


 Menno Deij - van Rijswijk

 Hello.

 I need to compile ParaView 4.3.1 with MPI. I tried different settings but
 I can't get rid of this error:

 /usr/bin/ld: warning: libmpi_cxx.so.1, needed by
 ../lib/libvtkPVServerManagerApplication-pv4.3.so.1, not found (try using

 /usr/bin/ld: warning: libmpi.so.1, needed by
 ../lib/libvtkPVServerManagerApplication-pv4.3.so.1, not found (try using
 -rpath or -rpath-link)

 I use OpenMPI 1.8.4 that was successfuly compiled and installed in
 /Programs/openmpi-1.8.4/build (not into system directories, I need to have
 programs installed into custom directories). So I set the following options
 for MPI:

 -L/Programs/openmpi-1.8.4/build/lib/
 MPI_Fortran_LINK_FLAGS:STRING=
 MPI_LIBRARY:FILEPATH=-lmpi_cxx -L/Programs/openmpi-1.8.4/build/lib
 It's a copy from the Makefile without comments. Actually I used ccmake to
 configure and generate Makefile.

 Compilation is normal until 98%. Then a number of errors appear because
 the linker cannot find MPI libraries (libmpi.so.1 and libmpi_cxx.so.1). I
 verified that these files are in /Programs/openmpi-1.8.4/build/lib/
 (searched with file manager to avoid typos, files are there). The
 interesting moment is that libmpi.so and libmpi_cxx.so are found (I don't
 point to *.so files, point only to lib directory). But then linker don't
 want to follow symlinks (libmpi.so = libmpi.so.1), if I get it right.

 I attached CMakeCache.txt file. If it's needed, I will post other details
 (Makefile + CMakeCache are too big for 500 KB limit of mailing list).

 Please, help me to compile ParaView with OpenMPI.
 Thanks.

[Paraview] Contour Plots

Folks,
New to paraview, but making some progress.
One thing I have not found a way to make a countour plot where there is a black 
line separating every Nth contour level.
Manual is not that much help
Can this be done directly with the baseline tool?
Thanks

Subject: Re: [Paraview] Mass weighted, mass flow weighted averages.

I think the best way would be to use the Calculator filter to compute your 
derived quantities (e.g. whatever field you want mass weighted divided by 
density) and then use the Integrate Variables filter to get the integrated 
values of the quantities. I'd need to see some equations before giving you a 
more precise set of instructions.
By the way, the ParaView User's Guide 
(http://www.paraview.org/paraview-downloads/download.php?submit=Downloadversion=v4.3type=dataos=alldownloadFile=TheParaViewGuide-v4.3-CC-Edition.pdf)
 is a good place to start getting familiar with ParaView. A printed edition is 
available but will have to be purchased at 
http://www.kitware.com/products/books.php. It has a couple more chapters that 
can be helpful to some users.

*Andy Bauer*
Thanks!
I don't know how to generate common field from partial blocks with
Calculator but I'm familiar with Extract Blocks cause I use it to extract
boundaries. AFAIR, I tried to integrate on the extracted boundary without
success but I will play with Extract Block filter in different ways, hope
I'll find the solution. If not, I will write on this mailing list (I have a
holydays for month so I will be online in august).

[Paraview] IntegrateVariables filter (add variables)

[Andrew]

Hello.
I tried WaveLet filter and IntegrateVariables works with it. But I need my
flow field variables (pressure, velocity e.t.c.) to be processed.
Calculator filter accept that variables (I can visualise result), but
Integrate filter doesn't see the result of Calculator (and it also
doesn't see any flow field variables if it's source is a results file or
cell data to point data). I gave a link on example files to be processed
in previous message (see below).
Thanks for your attention...




 Andrew (antech...@gmail.com) 02.07.2015

 Hello.
 Thanks for advice! I didn't try Wavelet source, but I will as soon as
possible
 and will report the result. Surely I can share an example of results:
 https://drive.google.com/open?id=0BzPt_Ya8Zu8nU2NRT2NWN1ZxV0U
 Files are in postprocessing directory (open the RESULTS.case file)
and have
 an EnSight Gold format.



 Andy Bauer andy.ba...@kitware.com 02.07.2015

 Have you tried doing the Integrate Variables filter with something like
the Wavelet
 source? If that works for you as expected, can you share a
representative data set that
 you're having problems with?

 I use ParaView to visualize Code_Saturne (CFD) calculation results

module in Salome). But I cannot integrate any variable except coordinates
and area or volume. I tried the Cell data to point data before
IntegrateVariables, it changed nothing. I asked this question on Salome and
CFD-Online forums, but noone replied me. Please, help.
Thanks.

[Paraview] [Catalyst] true time information instead of time step

[Andrew Ho]

I am using Paraview Catalyst (v. 4.2 since 4.3 doesn't seem to work with
Catalyst generated scripts) and I have data which has uneven true times:

0 0.1 0.15 0.18 0.25 ...

When I output data from Catalyst's generated scripts, it outputs a series
of files using the time step (0, 1, 2, 3, ...), but the true time
information appears to be gone.

How can I get this information back so I can properly annotate and view my
data?

I am using vtkImagaData and the outputted files are *.pvti and *.vti files
of the full dataset.

[Paraview] Plot 3D Function names

[Robertson, Andrew]

Folks,
I am new to paraview and while I am making some progress with the tool, I have 
not been able to figure out a few things
I get a lot of data in plot3D format.
The data in question is in the function file
Paraview simply sees these as function1, function2 etc
Is there someplace I can actually specify text for those?
Thanks
-Andy

[Paraview] Headlight in 4.3.1?

[Bosler, Peter Andrew]

Good morning,

I have just upgraded to Paraview 4.3.1 from 4.10, because I was unable to 
change the specularity of a surface in 4.1 (this is fixed in 4.3, which is 
nice).  But now I can't find the headlight option that used to be in 4.1's 
render view options.

Without it, the images I need to produce for a publication look dark and washed 
out.

Could you point me toward the lighting tool in 4.3 that lets me turn on a 
headlight?

Thanks for your time,

Pete Bosler

Peter,

You can find the headlight by looking in the Properties panel under
the Lights section. This is an advanced setting, so click the gear
icon in the Properties panel to expose it. Under the Lights section in
the panel (it's towards the bottom), click the Edit button and
select Additional Headlight in the Lights Editor dialog that pops
up.

Hope that helps,
Cory

[Paraview] Specify TCP interface for pvserver to listen on

[Andrew Porter]

Hello,

In a nutshell; can one somehow specify the TCP interface on which 
pvserver listens for connections?


The background:

I've been using pvserver on a remote machine and connecting to it from 
behind a firewall without problems for a while.
However, the remote machine has recently been re-configured and the 
login nodes now have two TCP interfaces, only one of which is publicly 
accessible. Unfortunately the pvserver is binding to the 'private' 
interface and thus I cannot connect to it.
I've tried using an ssh tunnel from the public interface to the private 
interface but unfortunately I get an 'administratively prohibited' 
message from ssh when I try to connect.


Does anyone know of a solution?

Thanks very much,

Andy.

[Paraview] Parametric functions.

[Andrew Maclean]

A while back there was a request for something different from the usual
sphere source.

So I have created an xml file to access the parametric surface functions in
ParaView along with a reverse sense programmable filter. It was an
interesting exercise that revealed some deficiencies in the parametric
function implementations that have been fixed in the VTK master.

I am happy to contribute this if people feel it will be useful.

Just let me know how.


Regards
Andrew

[Paraview] Potential bug in vtkPolygon normal and area calculations

[Andrew Parker]

Dear all,

This is driving me round the bend. When I have a meshing coming from a
rectilinear source, I get NANs from my normal and face area calculations.
 When all other input meshes are used, i.e. unstructured, the results are
correct. To test this I've written the following test code which makes a
single cell mesh and produces the NANs.  I then demonstrate that by using
the transform classes, with zero rotation, I can then extract the same mesh
back as a structured grid, and the errors disappear.  I can also apply a
non-zero rotation and the errors disappear too.

Note I apply a rotation, zero or otherwise, because my hypothesis having
stepped through 6.1 in the debugger, is that the vtk_pixel cell type (axis
aligned) coming from the rectilinear grid does not play well with the
normal calculation.  But I can't find the bug, only that all entries of the
normal are zero and the rest of the function fails.

Clearly, and more likely, is that I could also not be using the classes
correctly, and if so please let me know??  Hope somebody can find the bug,
I've got nowhere on this after a day of looking.  Again, anything non-axis
aligned and or non vtk_pixel would appear to work as expected.

Help appreciated,

Cheers again,
Andy

[Paraview] dlclose assertion error with boost::regex

[Andrew Ho]

I am trying to build a server plugin which utilizes the boost::regex
library, and for some reason when I quit paraview I get this message:

Inconsistency detected by ld.so: dl-close.c: 762: _dl_close: Assertion
`map-l_init_called' failed!

I've setup a basic project which demonstrates the issue:

CMakeLists.txt:

find_package(ParaView REQUIRED)

find_package(Boost COMPONENTS regex REQUIRED)

include(${PARAVIEW_USE_FILE})


ADD_PARAVIEW_PLUGIN(RegexProblem 1.0

  SERVER_MANAGER_XML reader.xml

  SERVER_MANAGER_SOURCES main.cpp

  )


target_link_libraries(RegexProblem PRIVATE

  ${Boost_REGEX_LIBRARY}

)


Then I added a simple regex search to the RequestData function:


#include boost/regex.hpp


int main::RequestData(vtkInformation *request, vtkInformationVector
**inVec, vtkInformationVector *outVec)

{

  std::string base_name = ab12cd34;

  boost::regex last_num(\\d+$);

  boost::match_resultsstd::string::iterator match;

  // The next line is the one which triggers the issue

  boost::regex_search(base_name.begin(), base_name.end(), match, last_num);

  return 1;

}


I don't have any issues with other libraries (filesystem, system, hdf5).

I've also tried creating a separate executable which calls dlopen/dlclose
on the library and have had no issues.

Is there something I'm doing wrong, or is a fundamental issue with
ParaView/my OS? I'm running 64-bit Ubuntu 14.04. I'm using the git master
(v4.1.0-934-g29029db)

The one thing I can do to get this message to go away is to change the
target_link_libraries to INTERFACE, but then the code will crash on trying
to run RequestData because it can't find the symbols.

[Paraview] Building ParaView with QT 5.3

[Andrew Maclean]

Has anyone been able to do this?
I am using Linux with Qt5.3 and CMake 3.0.0.
I have set PARAVIEW_QT_VERSION to 5
QT 5.3 is found OK
It seems that there is an issue with double colons in target names as
evidenced by  the CMake generation warnings raised:

CMake Warning (dev) at VTK/CMake/vtkModuleMacros.cmake:497 (add_library):
  Policy CMP0028 is not set: Double colon in target name means ALIAS or
  IMPORTED target.  Run cmake --help-policy CMP0028 for policy details.
  Use the cmake_policy command to set the policy and suppress this warning.

  Target pqWidgets links to target Qt5::Test but the target was not
  found.  Perhaps a find_package() call is missing for an IMPORTED target,
or
  an ALIAS target is missing?
Call Stack (most recent call first):
  VTK/CMake/vtkModuleMacros.cmake:581 (vtk_add_library)
  Qt/Widgets/CMakeLists.txt:288 (vtk_module_library)
This warning is for project developers.  Use -Wno-dev to suppress it.

and so on until

CMake Warning (dev) at VTK/CMake/vtkForwardingExecutable.cmake:91
(add_executable):
  Policy CMP0028 is not set: Double colon in target name means ALIAS or
  IMPORTED target.  Run cmake --help-policy CMP0028 for policy details.
  Use the cmake_policy command to set the policy and suppress this warning.

This warning is for project developers.  Use -Wno-dev to suppress it.

Generating done


From what I understand CMake 3.0.0 is searching for targets, then files on
disk which is the OLD behaviour. So this may not be the problem as I have
been unable to build with earlier versions of CMake.

The build then fails, after VTK is built, with (if testing is set):

[Paraview] vtkStructuredGrid not showing

[Andrew Ho]

Hi,

I'm having some issues getting a structured grid to be rendered in ParaView
with a plugin I'm writing.

What I have is my own class extending vtkStructuredGridAlgorithm.

My RequestData method: http://pastebin.com/uxSk3n5b

I'm pretty sure that my generation code is working correctly as I can plug
it into the standalone VTK example and everything works as expected (
http://www.vtk.org/Wiki/VTK/Examples/Cxx/StructuredGrid/StructuredGrid).

Additionally, after I apply my algorithm, the Information tab lists the
correct statistics:
2 cells
6 points
density data array with 6 elements
extents and bounds are both [0,1,0,2,0,0] which appears to be correct

 I'm using ParaView 4.1 in Ubuntu 14.04 (x64)

This seems to be similar to an issue posted back in 2011:
http://public.kitware.com/pipermail/paraview/2011-June/021872.html

As a note I have tried writing a simple XDMF file which creates a 2D
structured mesh and that loads just fine. However, strangely enough the
extents are in a different order than what I thought they should be ([0, 0,
0, 1, 0, 2])

[Paraview] Naming an existing data array.

[Andrew Maclean]

I have a source object that produces a polydata object. Unfortunately the
normals and scalars are unnamed. How do I access these and name them in
ParaView.
I thought something like this may work in a Programmable Filter:

pdi = self.GetPolyDataInput()

pdo =  self.GetPolyDataOutput()

pdi.GetNormals().SetName('Normals')

pdi.GetScalars().SetName('Scalars')

pdo = pdi


However, I can't see the array names.

This sort of thing works Ok in a Python Script:
# Name the arrays

randomHillsSource.GetOutput().GetPointData().GetNormals().SetName('Normals')

randomHillsSource.GetOutput().GetPointData().GetScalars().SetName('Scalars')
# pd = randomHillsSource.GetOutput().GetPointData()
# print pd

Is it possible to do this on ParaView?

Thanks in advance for any help.

Andrew

[Paraview] ParaView Qt5 progress

[Andrew Maclean]

I attempted a build with ParaView and QT5.3 (RC 3) on the latest version of
Ubuntu and I get the following message:

CMakeFiles/QtTesting.dir/pqNativeFileDialogEventPlayer.cxx.o: In function
`pqNativeFileDialogEventPlayer::start()':
/home/amaclean/Development/Kitware/src/ParaView/ThirdParty/QtTesting/vtkqttesting/pqNativeFileDialogEventPlayer.cxx:122:

There are also undefined references to qt_filedialog_open_filenames_hook
and qt_filedialog_save_filename_hook.

I have set PARAVIEW_QT_VERSION to 5.

I also note that VTK builds successfully with QT 5.3.

Has anyone else had problems building with QT5?

[Paraview] Explicit numbering of nodes indexes in Xdmf/h5

[Andrew Parker]

All,

I thought I'd forward this onto the paraview lists in case somebody could
think of a way to do this?  Please see my email below which I originally
sent to the vtk user list.  Any help would be very much appreciated,
including the fact that it just cannot be done.  I would in particular
welcome thoughts from those who have helped develop the xdmf2 lib within
the paraview source.

Many thanks again,
Andy

[Paraview] Explicit numbering of nodes indexes in Xdmf/h5

[Andrew Parker]

All,

I thought I'd forward this onto the paraview list in case somebody could
think of a way to do this?  Please see my email below which I originally
sent to the vtk user list.  Any help would be very much appreciated,
including the fact that it just cannot be done.  I would in particular
welcome thoughts from those who have helped develop the xdmf2 lib within
the paraview source.

Many thanks again,
Andy

Re: [Paraview] Explicit numbering of nodes indexes in Xdmf/h5

[Andrew Parker]

Hi Jason,

Many thanks for your reply.  In my case I'm not quite sure how attributes
would help me, but I may not fully understand how they work.  As I posted
in the second xmf example file in my last email, given 4 nodes with 4
unique positions, I can completely define the plane topologically by
writing the node numbers out in the correct order, their actual
label/value/number doesn't matter (as long as it consistently refers to the
correct position).

In my example I used [300 20 22 80] as the node labels to define a 2D
plane.  However, my current understanding of xdmf(2) is that I would need
to supply in the geometry section (regardless of GeometryType) 301 x, y and
z node positions (even if 297 are just zeros), just so that I could conform
to the zero-based implicit numbering of that section.  That allows paraview
to index that data and pick out (the only) 4 positions it requires to
define the plane.

I'm asking whether there is a way round this so that, as I gave as an
example in my second xmf file, one could additionally provide an explicit
node number next to each x,y,z position so that the implicit zero-based
numbering could be skipped and only 4 x,y,z positions needed to be added to
the file in addition to their label/value/number.

Can attributes do this?  If so could you provide a quick example, ideally
just with reference to the second example file I included in my email?  Do
you have a link to the xdmf(2) mail list?

Many thanks again,
Andy

 Hello Andy

 The XDMF2 library has the ability to assign Attributes and Information
 data to Geometry objects. So you wouldn't be changing the node numbers,
 you'd just be adding a new Attribute that has different values at each
 node, and you'd need to display this new Attribute in Paraview instead of
 the node numbers.

 Since you mentioned offsets for XDMF arrays: I've been working on an XDMF2
 implementation for ADCIRC, a finite element coastal ocean model. Being a
 fortran code, ADCIRC uses 1-offset arrays, while the XDMF2 standard is
 0-offset.

 Its easy enough for us to subtract 1 from the node numbers in the element
 table when storing mesh data as XDMF2, reversing the operation upon read
 into ADCIRC or leaving them as-is for reading into Paraview. However, when
 looking at node and element number labels on ADCIRC data in Paraview, the
 analyst has to remember that all the displayed values are actually off by
 1.

 I emailed the XDMF mailing list and got a reply from the primary
 developers that they were previously unaware of the demand for 1-offset
 arrays, but they are now researching the possibility of adding this.

 Your case is a little different, since it seems you are interested in
 arbitrary node numbering. But I thought I would mention the above
 background info for completeness. As I said, XDMF2 Attributes may be the
 solution for you.

[Paraview] How to use vtk sequence of files to animate them?

[Andrew Somorjai]

Hello,

Thus far this is what I've accomplished with Paraview but I cannot seem to get 
my animation to run properly as I will explain at the end.

1. I took a sequence of 30 vtk format files made by Athena (MHD numerical 
software) and imported all of them into paraview.
2. I added every single one of them to the animation view.
3. I changed each vtk grid to only run for 1 second and each vtk is a frame 
with 30 seconds and 30 frames total.
    Basically frame 1 is before frame 2 and so on and none of them overlap in 
time.
4. I noticed that toggling a  eye in the pipeline browser turns off specific 
vtk grids in the 3d viewer and for some reason this is where things don't work.

If I select all of the eyes and turn them on only the last one turned on 
causes the selected 3d vtk grid to appear. I can only render that image when I
try to animate all the 30 frames using file-save animation-avi. I expect that 
at each frame every second a different grid would show and get animated.

Please feel free to ask more questions regarding my setup. I would post 
screenshots but the mailing list is archaic as this is 2013 and better 
alternatives exist now.

[Paraview] Median Dual Mesh Construction

[Andrew Parker]

Hi,

Just a quick one.  Is there any filter in vtk/paraview to obtain the median
dual of a mesh?  I'm happy to assume the cells are know cell types, but
would want it for any input type of mesh.

Anybody had success with something like this in vtk?

Re: [Paraview] Construct 3D revolved mesh from a 2d mesh

[Andrew Parker]

Sorry to repost.  Does anybody have a feel for whether I can apply a filter
and essentially produce a 3d volume mesh with associated scalars and
transformed vectors, from it's 2d counter part using vtk?

i.e. a cylindrically symmetric simulation converted to a valid 3d volume
mesh.  I can apply the filter, similar to this thread:

http://www.paraview.org/pipermail/paraview/2012-March/024320.html

but in my case, rather than for presentational purposes, I need the
internal of the rotated shell to be a populated volume mesh.  Using the
method in the above post, or described in my previous post gives only the
outer shell.

Any help either way really appreciated!

Cheers,
Andy


All,

 I am doing this in code using vtk, but can be reproduced using paraview as
 noted below.

 I have a 2d mesh which represent a cylindrically symmetric simulation.  I
 want to be able to revolve this around the z-axis to create a 3d mesh.
  However, when doing this using the rotational extrusion filter, I only
 seem to have boundary faces.  I can't get this to give me 3d cells inside
 the volume of revolution, which is what I'm after.  Can this be done?  I
 have done this in visit and sure enough the mesh is inside the volume of
 revolution as I expect.

 This can be reproduced in paraview using the UCD_3.inp example from
 the data set.

 First apply a transform and rotate around 90 degrees round the y axis.
  Then apply the extract surface filter. I too must do this in my code as
 the incoming mesh is a vtkUnstructuredGrid and the rotational extrusion
 filter wants a polydata.  Then apply the rotational extrusion filter for
 360 degrees with 120 resolution.  Finally perform an x-normal slice at the
 default position.  Viewing only the slice shows the outer boundary only,
 but I had wanted the interior of the boundary to be populated with a mesh,
 not bothered about its topology, just want a fully populated mesh within
 the interior.

 Again, any help on the above really appreciated??  As I say achieved with
 visitwhich I mention only because I assume the code under the hood
 would be vtk and hence possible in my case.

 Many thanks,
 Andy

[Paraview] Possible vtkOBBTree bug or weirdness

[Andrew Parker]

Hi,

So I've been having some problems with vtkOBBTree using the
intersectWithLine method with the following signature:

int IntersectWithLine (double a0[3], double a1[3], double tol, double t,
double x[3], double pcoords[3], int subId, vtkIdType cellId,
vtkGenericCell *cell)

In particular, depending on what I have initialised some of the input
parameters to, which I had assumed and the code and docs indicate their
initial values are not important, with exception of a0, a1, and tol(0,0), I
got different results.  Having looked at the tree, I found that I had
forgotten to set the tolerance, it was undefined in the class and unset.
(might be good if a sensible default got set, this too could be defined as
a bug...)  Anyway, correcting that and setting the tolerance to zero I then
got this:

Percentage Complete: 2Generic Warning: In VTK/Common/vtkMath.cxx, line 736
vtkMath::Jacobi: Error extracting eigenfunctions

A lot.  Looking at the code, the following comment is a bit worrying:

   this is NEVER called
  if ( i = VTK_MAX_ROTATIONS )
{
vtkGenericWarningMacro(
   vtkMath::Jacobi: Error extracting eigenfunctions);
return 0;
}

I need a locator that can let me intersect with a line, and given me back:
1) the cell that it intersected with,
2) the location of the intersection.

Also I found in some instances 't' was bigger than one, which I understood
to not be possible.

Any help, and advice on an alternative intersector that can give me back
the above would be great as my choice of vtkobbtree was almost random

Cheers,
Andy

[Paraview] 3.98-rc2 and multiple selections

[Andrew Parker]

Hi,

So as requested, I built the latest rc against 4.7.2 and that also happens
to be built against qt 4.8.3, and it compiles and installs fine. This is
built against openmpi 1.6.2 with use_mpi on.  However, I have noticed that
when loading multiple files around 20 of them, vtu's in this instance, each
representing a sub part of the domain, after apply is pressed it only opens
the last file in the list.  I had to go through each file, 20 odd and click
apply on each to see them all.  Don't know if this is a known bug, or is a
feature change and I'm now doing it incorrectly, but this does not behave
the same as 3.14.1 would be nice if you only needed to press apply once
as before.

Hope the info is useful,
Cheers,
Andy

[Paraview] Bug with 4.7.2 build and 3.14.1

[Andrew Parker]

Hi,

I get this error building a fresh clone of 3.14.1 using gcc 4.7.2, vtk
build and works perfectly fine with this compiler so I presume it's a
slight change in ordering that has caused the problem.:

[ 30%] Building CXX object

Seems very simple, just seems to me to be a missing #include stdint.h,
fixing it by including said header in the cxx file above, then gives this:

ParaView/VTK/Rendering/vtkFreeTypeTools.cxx:229:46: error: ‘intptr_t’ was
not declared in this scope

including this again inside the cxx fixes this too and it seems to go
through fine.  Probably too late for 3.14.1 but might be of use for
3.98?

Let me know if this was the wrong thing to use?? As I've change my local
copy to reflect the above.

Andy

Re: [Paraview] [vtkusers] vtkDistributedDataFilter and ghost cells

[Andrew Parker]

Hi mate, how goes it?

How do you set the ghost level to be one rather than default zero then?
 Have you written your own downstream filter to update the number of
ghost levels?  If so any tips?

If you know the name of a global node ID array in the input dataset, set
that name with this method... Which method??  How do I set this?  I could
probably work out the global node and cell numbers and stick them into the
meshes that I pass to D3.  But how do I do that?  What method do I call to
set them, and what name do I give them this method ain't that helpful
in the docs ;-)

Cheers,
Andy

 Hi Andy,

 I've had a few problems with D3.  The limitation I find is that global
 node ids are slow to generate and the point merging (I think) is only
 performed in single precision.  Also, remember that everything will be
 redone each time the number of ghost levels that are requested changes -
 this means the global ids are recalculated, it is repartitioned and then
 the number of ghost levels are added.  In some ways it might be better to
 have D3 split into 3 filters for the different steps although it would make
 a long pipeline.

 Btw looking at the docs it seems to suggest that it only creates temporary
 arrays for global ids within d3 (although I think in the past I have had
 access to the global ids it created):

 If you know the name of a global node ID array in the input dataset, set
 that name with this method. If you leave it unset, D3 will search the input
 data set for certain common names of global node ID arrays. If none is
 found, and ghost cells have been requested,* D3 will create a temporary
 global node ID array* before acquiring ghost cells. It is also desirable
 to have global element IDs. However, if they don't exist D3 can create them
 relatively quickly. Set the name of the global element ID array if you have
 it. If it is not set, D3 will search for it using common names. If still
 not found, D3 will create a temporary array of global element IDs.


 My filters now add their own global ids so I don't use d3 for that.

 Paul

  Hello,
 
  Since the data is essentially structured (rectilinear grids), I think
  the best way to get the global/local mapping is to use extent
  information. Specifically, you need the whole extent of the grid and
  the global extent of each partition. Then from the global IJK of a
  point or cell, and the whole extent you can use methods from
  vtkStructuredData to compute the corresponding global linear index for
  a point or cell. Do you have extent information?
 
  Also, I have done some work on ghost generation in VTK for structured
  (and AMR) data. Unfortunately, currently it doesn't work outside the
  box with rectilinear grids. This functionality can still be used to
  create ghost layers and exchange the fields (node and/or cell data) on
  the grid but, it doesn't communicate the coordindates on the
  rectilinear grid. Alternatively, you may be able to converge to a
  solution faster if you convert the rectilinear grid to a
  vtkStructuredGrid and use vtkPStructuredGridConnectivity or
  vtkPStructuredGridGhostDataGenerator to generate ghost layers. There
  are tests that illustrate how to use these classes and I can provide
  more information if you are interested.

Re: [Paraview] vtkDistributedDataFilter and ghost cells

[Andrew Parker]

So that's working now in terms of the cast, forgot GetOutput() inside the
cast operator!  The returned vtkUGrid is now fully populated and contains
sensible information.

However, both getPointData()-GetGlobalIds()  and
 getCellData()-GetGlobalIds() return null pointers.  Any thoughts?

Also, should I be using CellData since I want the cell global to local
mapping for cells not the nodes, at the moment at least?

   Another question which I'd forgotten, how do I get to a
 vtkUnstructuredGrid per processor from the vtkDistributedDataFilter.

  For instance, dd-GetOutput()-GetPointData()-GetGlobalIds() doesn't
 work as it's a vtkDataObject

  Stupid question I'm sure but the doxy notes say this type returns an
 unstructured mesh, but I can't seem to get it out?

  Also, why exactly do I need the vtkPieceScalars and
 vtkDataSetSurfaceFilter again? If the above can be made to work and
 return the mapping, what are they adding in terms of information?

  Thanks again,

Re: [Paraview] [vtkusers] vtkDistributedDataFilter and ghost cells

[Andrew Parker]

Many thanks for that.  I perform some threshold stuff early on, so
basically I'm working with unstructured grids pretty much from zero.  I
think I need to try to populate the ghost cells using the approach Ken
suggested, but I'm not sure how to do that both from a conceptual point of
view - I'd just be copying Ken's code, but also from the perspective of
fitting into my code design.

There does seem to be some confusion surrounding ghost cells and local to
global cell mappings both in terms of which class computes/owns them and
when and how.  Is that fair? I had assumed that given the massive amount of
work that D3 is doing, it would (must have) computed this info and have
been readily available via get methods, rather than going down the route of
extending the class just to define my own virtual methods

These things are basic sets of info for parallel computing and I would have
assumed others would have wanted them but there is a lack of usage examples
and postsnot a complaint just surprised given that basically you can't
get going with vtk in parallel unless you use something like D3 for the
type of things I want to do.  i.e. local processing and some exchange over
halos

It is odd that I also can't get cell local to global out of the box as Ken
said...

Going to have a go with Ken's method and see where I get to.  Are there any
good examples of creating and using ghost cells with unstructured meshes
that you could recommend??

 Hello,

 Since the data is essentially structured (rectilinear grids), I think
 the best way to get the global/local mapping is to use extent
 information. Specifically, you need the whole extent of the grid and
 the global extent of each partition. Then from the global IJK of a
 point or cell, and the whole extent you can use methods from
 vtkStructuredData to compute the corresponding global linear index for
 a point or cell. Do you have extent information?

 Also, I have done some work on ghost generation in VTK for structured
 (and AMR) data. Unfortunately, currently it doesn't work outside the
 box with rectilinear grids. This functionality can still be used to
 create ghost layers and exchange the fields (node and/or cell data) on
 the grid but, it doesn't communicate the coordindates on the
 rectilinear grid. Alternatively, you may be able to converge to a
 solution faster if you convert the rectilinear grid to a
 vtkStructuredGrid and use vtkPStructuredGridConnectivity or
 vtkPStructuredGridGhostDataGenerator to generate ghost layers. There
 are tests that illustrate how to use these classes and I can provide
 more information if you are interested.

  As far as global cell IDs are concerned, you are out of luck.
  vtkDistributedDataFilter does not create them. But they are not all that

 is

And I add this to a .h file:

4) If I had created the ghost cells, how would I know, is my next question.
 How can I visualise them to check?

Any thoughts really welcome.

Ok thanks again for the advice.  Think it's really clear I'm confused
between the downstream nomenclature.  Do mean just a class that
constructs or takes a D3 as input that I write from scratch outside of vtk?
Or do you mean something totally different?  Clearly my understanding of
it was to inherit was totally wrong.  I would prefer to stick with the
downstream filter if that's more robust.

Could you give me a quick explanation in this context?  In addition could
you point me towards an example of using a downstream filter in this
context?

Sorry again for the confusion,

  If you want to modify D3 itself (which sounds like a reasonable good idea

 go with this approach, first blow away your RequestUpdateExtent method.
  Let D3 do its regular thing.  Then implement a RequestData method like the

  int MyD3::RequestData(

   I don't know if the executive is going to get upset about you changing

[Andrew Parker]

Hi,

Hope you can help.  I have some code running in parallel, that by other
means I have constructed nprocs worth of vtkRectilinearGrids, one per
process.  Each of which is a valid nprocs-worth of the whole serial mesh,
I've check this and I am happy with that i.e. it's partitioned properly and
nothing is missing.  I need the following information to process my data in
parallel:

1) I would like the local - global cell mapping between the local rgrid
and the corresponding global single mesh.
2) I would like to know which cells are on processor boundaries for
parallel exchange purposes.
3) I would like all the double arrays per processor to be expanded by the
amount of (1 level of) ghost cells such that I can properly do the
computations I want with the ability to exchange only those additional
cells given the local to global mapping.

I have tried from the examples to use the following code, which I call on
every process, each of which has it's own local rgrid as I said.  I do the
following:

 vtkSmartPointervtkDistributedDataFilter dd =
vtkSmartPointervtkDistributedDataFilter::New();
  dd-SetInput(rgrid);

 dd-SetController(getVtkController());
  dd-SetBoundaryModeToSplitBoundaryCells();
 //dd-SetBoundaryModeToAssignToOneRegion();
 //dd-SetBoundaryModeToAssignToAllIntersectingRegions();
 dd-UseMinimalMemoryOff();
 dd-Update();
  vtkPieceScalars *ps = vtkPieceScalars::New();
 ps-SetInputConnection(dd-GetOutputPort());
 ps-SetScalarModeToCellData();
  vtkDataSetSurfaceFilter *dss = vtkDataSetSurfaceFilter::New();
 dss-SetInputConnection(ps-GetOutputPort());

The dd object works fine and writing its contents out on each processor
gives nprocs worth of meshes, each of which look slightly different to the
way I've partitioned them up, but sum to the same serial mesh so I am happy
with that working correctly. But I can't for the life of me figure out how
to obtain local to global cell mappings, allocate ghost cells, or work out
how to exchange data given the above partition info and comms

Note I have not provided any additional information to dd regarding
global cells as per the doxy notes so I assume it went away and computed
it.  I can't figure out how to extract it however.  I also have no idea how
to modify each local processor rgrid to include the ghost cells for that
processor.  Finally given that info, I could exchange between processors to
write to each local processors ghost cells the corresponding real cell
data from the neighbouring meshes and continue the code.

Any help really appreciated!

Cheers,
Andy

Re: [Paraview] vtkDistributedDataFilter and ghost cells

[Andrew Parker]

Many thanks for this.

So I need to rethink my design such that I extend from a filter so I can
obtain the ghost cells?  There is no way to obtain them just from dd?

I can't do dd-GetGhostCells(processorNumber)?
or rgrid-AddGhostCells(dd)?

I know I can't do these last two, but that's kind of the thing I was
after

are there any other ways to do this?  Casting my current work in terms of a
filter is not going to be straight forward, although equally I'll have to
if this is the only wayso other ideas welcome.

Re: [Paraview] vtkDistributedDataFilter and ghost cells

[Andrew Parker]

Another question which I'd forgotten, how do I get to a vtkUnstructuredGrid
per processor from the vtkDistributedDataFilter.

For instance, dd-GetOutput()-GetPointData()-GetGlobalIds() doesn't work
as it's a vtkDataObject

Stupid question I'm sure but the doxy notes say this type returns an
unstructured mesh, but I can't seem to get it out?

Also, why exactly do I need the vtkPieceScalars and
vtkDataSetSurfaceFilter again?
If the above can be made to work and return the mapping, what are they
adding in terms of information?

Thanks again,
Andy

  Ghost cells are only created on demand, and this is usually done by
 pipeline convention.  If you have a filter that needs a layer of ghost
 cells, it should override the RequestUpdateExtent method to increment the
 value of UPDATE_NUMBER_OF_GHOST_LEVELS from the output information to the
 input information.  This method would look something like this.

   int vtkDistributedDataFilter::RequestUpdateExtent(
   vtkInformation *vtkNotUsed(request),
   vtkInformationVector **inputVector,
   vtkInformationVector *outputVector)
 {
   // get the info objects
   vtkInformation *inInfo = inputVector[0]-GetInformationObject(0);
   vtkInformation *outInfo = outputVector-GetInformationObject(0);

int piece, numPieces, ghostLevels;

// We require an extra layer of ghost cells from upstream.

piece =
 outInfo-Get(vtkStreamingDemandDrivenPipeline::UPDATE_PIECE_NUMBER());
   numPieces =

 outInfo-Get(vtkStreamingDemandDrivenPipeline::UPDATE_NUMBER_OF_PIECES());
   ghostLevels =
 outInfo-Get(
 vtkStreamingDemandDrivenPipeline::UPDATE_NUMBER_OF_GHOST_LEVELS());

inInfo-Set(vtkStreamingDemandDrivenPipeline::UPDATE_PIECE_NUMBER(),
 piece);
   inInfo-Set(vtkStreamingDemandDrivenPipeline::UPDATE_NUMBER_OF_PIECES(),
   numPieces);

 inInfo-Set(vtkStreamingDemandDrivenPipeline::UPDATE_NUMBER_OF_GHOST_LEVELS(),
   ghostLevels);

return 1;
 }


  The operation of the RequestData method should also strip off this layer
 of ghost cells.  It might be possible to request a layer of ghost cells by
 setting UPDATE_NUMBER_OF_GHOST_LEVELS at the bottom of the pipeline, but
 I'm not totally sure how to make that work.  It's probably easier (or at
 least cleaner) to do it from within a filter.

 Subject: [EXTERNAL] [Paraview] vtkDistributedDataFilter and ghost cells

   Hi,

  Hope you can help.  I have some code running in parallel, that by other
 means I have constructed nprocs worth of vtkRectilinearGrids, one per
 process.  Each of which is a valid nprocs-worth of the whole serial mesh,
 I've check this and I am happy with that i.e. it's partitioned properly and
 nothing is missing.  I need the following information to process my data in
 parallel:

  1) I would like the local - global cell mapping between the local rgrid
 and the corresponding global single mesh.
 2) I would like to know which cells are on processor boundaries for
 parallel exchange purposes.
 3) I would like all the double arrays per processor to be expanded by
 the amount of (1 level of) ghost cells such that I can properly do the
 computations I want with the ability to exchange only those additional
 cells given the local to global mapping.

  I have tried from the examples to use the following code, which I call
 on every process, each of which has it's own local rgrid as I said.  I do
 the following:

   vtkSmartPointervtkDistributedDataFilter dd =
 vtkSmartPointervtkDistributedDataFilter::New();
   dd-SetInput(rgrid);

  dd-SetController(getVtkController());
   dd-SetBoundaryModeToSplitBoundaryCells();
  //dd-SetBoundaryModeToAssignToOneRegion();
  //dd-SetBoundaryModeToAssignToAllIntersectingRegions();
  dd-UseMinimalMemoryOff();
  dd-Update();
   vtkPieceScalars *ps = vtkPieceScalars::New();
  ps-SetInputConnection(dd-GetOutputPort());
  ps-SetScalarModeToCellData();
   vtkDataSetSurfaceFilter *dss = vtkDataSetSurfaceFilter::New();
  dss-SetInputConnection(ps-GetOutputPort());

Re: [Paraview] vtkDistributedDataFilter and ghost cells

[Andrew Parker]

Thanks on both accounts.  Any thoughts why the downcast called after
dd-Update() on distributedDataFilter is a null pointer?  As in, dd is
working perfectly properly, but I don't seem to be able to extract a valid
unstructuredgrid.  For a follow up question I assume
getPointData()-GetGlobalIds() gives the local to global for the mesh
nodes, and I should use getCellData()-GetGlobalIds() to get the local to
global for the cells?  Once I get a valid pointer that is
