Re: [Paraview] [EXT] RE: Python Annotations

[Quentin d'Avout]

Thank you Dennis.

All, I'm looking for which code (if any) is used for special characters,
superscripts, etc. to insert in annotations, graph legends, plots, etc.

Any ideas welcome.
Thanks

[Paraview] FEM

[paul . carrico]

Dear All 

I'm new in Paraview community. 

For a while, I'm thinking in developping my own template in order to
post-process results in Paraview, from my finite element solvers
(mechanical and thermal ones). 

>From an ascii file containing all the data (mesh informations and
nodal/element results), I'm thinking in writing (python) routines in VTK
format I guess. 

One can find a lot of information's on internet, but are ther some
specific docs/tools/class and so on on it? 

Thanks for any feedback

Re: [Paraview] server-side InvokeEvent(...) doesn't call client-side observer

[Kolja Petersen]

Ok, vtkSMLiveInsituLinkProxy::NextTimestepAvailable calls PushUpdatedState,
again pushing from client to server. I pasted the code below for
convenience.
I don't get it, where the communication in the opposite direction is
initiated. I have tried before, but the RMI and Qt signals+events usage
makes it impossible to follow the sequence of procedure calls.

  211 void vtkSMLiveInsituLinkProxy::NextTimestepAvailable(vtkIdType
timeStep)  212 {  213   this->TimeStep = timeStep;  214   // Mark all
extract producer proxies as dirty.  215
vtkInternals::ExtractProxiesType::iterator iter;  216   for (iter =
this->Internals->ExtractProxies.begin();  217iter !=
this->Internals->ExtractProxies.end(); ++iter)  218   {  219
iter->second->MarkModified(iter->second.GetPointer());  220   }  221
222   this->PushUpdatedState();  223   224
this->InvokeEvent(vtkCommand::UpdateEvent);  225 }  226   227
//
 228 void vtkSMLiveInsituLinkProxy::PushUpdatedState()  229 {  230
if (this->StateDirty)  231   {  232
vtkSMLiveInsituLinkProxyDebugMacro(<< "Push new state to server.");
233 // push new state.  234 vtkPVXMLElement* root =
this->InsituProxyManager->SaveXMLState();  235 std::ostringstream
data;  236 root->PrintXML(data, vtkIndent());  237
root->Delete();  238   239 vtkClientServerStream stream;  240
stream << vtkClientServerStream::Invoke << VTKOBJECT(this) <<
"UpdateInsituXMLState"  241<< data.str().c_str() <<
vtkClientServerStream::End;  242
vtkSMLiveInsituLinkProxyDebugMacro(<< "Push new state to
server--done");  243 this->ExecuteStream(stream);  244   245
this->StateDirty = false;  246   }  247 }

Mark,

You're simply missing a call to `this->SetNumberOfOutputPorts(1)` in
your constructor. That will get past the segfault.

Besides that, look at `vtkTemporalArrayOperatorFilter` as an example
for how to overload `RequestDataObject` to create correct output
dataset type, `RequestInformation` to determine which timesteps are
available, and `RequestUpdateExtent` to request a set of timesteps.

Re: [Paraview] [EXTERNAL] Re: boolean mesh filtering

[Cory Quammen]

Alan,

It would be possible to expose the boolean operations filter in ParaView
without much trouble. However, that filter is limited to
polydata-to-polydata intersection (a plus for Jeff's application), and
works best when the geometries overlap but do not share faces (a minus for
Jeff's application). For Jeff's needs, I don't think it would be that
useful.

Thanks,
Cory

Re: [Paraview] Python Scripting - Acess vtkOpenGL cameras from .pvx files information

[Utkarsh Ayachit]

Afraid not. One potential work around would be you build the
transformation matrix and set that on the camera. You can build the
matrix yourself by changing the order of rotations.

 Leo,

 You can't access it in Python since the Python script is not run on the
 server side. If your goal is to debug what thet camera is set to, you can
 put cout's to print the camera in
 `vtkCaveSynchronizedRenderers::HandleStartRender`. That's where the local
 camera on each rank is "prepped" for rendering a frame.

Re: [Paraview] Displaying volume outside of mesh as solid

[Moreland, Kenneth]

It looks like the email to the list at large is awaiting moderator approval for 
the attachment. In the meantime, here is the response without the referenced 
attachment.

Subject: Re: [Paraview] Displaying volume outside of mesh as solid

Sergey,

What Cory said is true that ParaView cannot directly render empty spaces. 
However, you might be able to get something close enough with the backface 
styling rendering controls. These controls let you render surfaces whose 
“outside” is facing you different than surfaces whose “inside” is facing you. 
They are an advanced property under “Display” in the properties panel. The 
easiest way to get to them is to type “backface” in the search box on the 
properties panel (as shown in the attached screenshot).

Try changing the “Backface Representation” to “Cull Frontface”. That tells 
ParaView to not render any part of the surface where the outside is facing to 
you. That should remove the outer surface in the front and instead show the 
inner surface that should be facing your hollow volume. The attached screenshot 
shows me using this to show a sphere clipped out of the center of a grid. You 
will note that you also see the back faces of the larger grids. That is 
inevitable. There is no way for ParaView to know the difference between the 
faces of your mesh that are on the interior hollow region and those that are on 
the external empty space.

(Note, that if “Cull Frontface” does not seem to show anything different, try 
“Cull Backface”. That might work if your surfaces are for some reason inward 
facing. That shouldn’t be the case, though, when ParaView is rendering the 
surface of a volume.)

I hope that helps.

There isn't anything in ParaView to view empty volumes. At some stage, the 
volume you are talking about needs to be represented by a grid or mesh for it 
to be visualized with ParaView. If you can generate a volumetric mesh outside 
of ParaView, then you could use all the visualization techniques in ParaView 
that apply to volume meshes. As a post-processing application, ParaView has 
essentially no built-in functions for generating volume meshes.

Hope that helps,
Cory

I need to reverse the solid and empty areas, so that non-meshed volume

Mesh is in 3D.

Is there a way to do this?

Thank you very much.

I've responded to the thread. Please note that Thursday-Sunday was a

slow.

While I am not sure which conversation you're referring to or whom you
were having that conversation, it's believable that there was
confusion between which data transfers you were referring to. All
communication between filters in a Catalyst in situ session is via
MPI. Only when you start doing "live" is when you encounter TCP. With
Live, currently the data transfer between the insitu ranks and the
"pvserver" ranks used for visualization is via TCP. Live support, in
my mind, is still in the early life cycle and needs more development
for production use.

Catalyst is indeed being actively developed and maintained. While we
try our best, responding to every mailing list inquiry can be quite
difficult. We do offer consulting services [1] if you want to work
Catalyst development team directly.

Hope that helps.

Re: [Paraview] server-side InvokeEvent(...) doesn't call client-side observer

[Utkarsh Ayachit]

Catalyst live-session is managed this custom engineering from both the
client and the server side. Hence it's not a mechanism that arbitrary
filters can use to communicate events from server to client. If you're
interested in how Catalyst live sessions manages this, start by
looking at vtkSMLiveInsituLinkProxy and vtkLiveInsituLink classes.
Following the code path for NEXT_TIMESTEP_AVAILABLE might be helpeful.

[Paraview] Misleading facts about Catalyst

[Kolja Petersen]

Heya,
I'd need some more reliable input on the Catalyst design.

Last week I asked how the server side can notify the client of recent
changes. Utkarsh wrote this wouldn't be supported by Paraview. After I
clarified that exactly this is happening during a Catalyst Live simulation,
the discussion was mute. I am still hoping for an answer how to notify the
client of any changes that might happen on the server side for example as a
result of some network activity.

Another example, some days before, I was wondering why Catalyst datasets of
considerable size take so long from the Insitu side to the Live
Visualization side, given that the Catalyst User Guide gives the impression
that everything is designed for high throughput. Someone insisted that
everything is transported through MPI until I mentioned that Paraview is
not designed for a dynamically added MPI communicator. Only then it was
explained that Catalyst data exchange is going through TCP...

The Catalyst development seems increasingly problematic. Have the Catalyst
developers left Kitware, or what is going on? We are trying to work on
improved solutions, but with the recent quality of comments we can't see
this happening.
Thank you
Kolja

Re: [Paraview] Segfault with simple C++ filter derived from vtkMultiTimeStepAlgorithm

[Utkarsh Ayachit]

Mark,

You're simply missing a call to `this->SetNumberOfOutputPorts(1)` in
your constructor. That will get past the segfault.

Besides that, look at `vtkTemporalArrayOperatorFilter` as an example
for how to overload `RequestDataObject` to create correct output
dataset type, `RequestInformation` to determine which timesteps are
available, and `RequestUpdateExtent` to request a set of timesteps.

Re: [Paraview] [EXTERNAL] SWKey: Way to Enlarge Upper Left Display Panel Icons for Picking Points and Cells?

[Scott, W Alan]

Understand.  My monitor resolution (i.e., retinas) behind my just discovered, 
early cataracts, isn't getting better either.  But, you would be surprised how 
many people complained about the font size of text in 5.3'ish.  Thus, the bug 
report on text size, and the bug report on icon size.

By the way, I discovered that one of my problems in Linux land was that 
anti-aliased fonts were not on.  Just use a zoom tool if you are interested in 
finding if you have the issue.  After a bit of googling, I got it to work.  
Greatly helped the fonts - but they still needed the ability to scale.

Re: [Paraview] Displaying volume outside of mesh as solid

[Cory Quammen]

There isn't anything in ParaView to view empty volumes. At some stage, the
volume you are talking about needs to be represented by a grid or mesh for
it to be visualized with ParaView. If you can generate a volumetric mesh
outside of ParaView, then you could use all the visualization techniques in
ParaView that apply to volume meshes. As a post-processing application,
ParaView has essentially no built-in functions for generating volume meshes.

Hope that helps,

Re: [Paraview] How to plot pressure map on an airfoil or circle?

[Cory Quammen]

Hi Eman,

The Warp By Scalar filter will warp a geometry, such as a circle, according
to a scalar field at each point in the geometry. The geometry must have a
Normals array set for this to work.

The Glyph filter can draw arrows scaled according to the scalar value at
your circular geometry.

HTH,
Cory

[Paraview] Animation Camera Assistance

[Elijah Andrews]

Hello all,

I'm looking for some help with this question: https://stackoverflow.com/ques
tions/47465192/camera-rotation-animation

I've copied the text here for your convenience:

I have simulated a rotating cube filled with particles by moving the
gravity vector rather than changing all of the geometry. I want to use the
ParaView animation tools to rotate the camera to keep the gravity vector
pointing down so it all looks right. When moving the camera (not
animations) I would use the rotate 90 degrees tools.

How would I achieve this effect for an animation?

Many thanks,
Elijah Andrews

[Paraview] ParaView: Qt runtime errors

[Nenad Vujicic]

Hello everyone,

I'm experiencing one strange situation with some of my ParaView plugin
exporters. When I create the scene, go to File->Export Scene, select output
filename and file-format, push OK and then it creates output file, but it
also reports some QT runtime errors in Output Window:

QWindowsWindow::setGeometry: Unable to set geometry 229x100+1024+492 on
QWindgetWindow/'QDialogClassWindow'. Resulting Geometry: 229x99+1025+592
(frame: 8, 31, 8, 8, custom margin: 0, 0, 0, 0, minimum size: 178x99,
maximum size: 16777215x16777215).

I get this error 2 times reported.

I first noticed this on my custom build, but, when I tried Kitware's
binaries (the latest one: ParaView-5.4.1-Qt5-OpenGL2-MPI-Windows-64bit), I
also got these errors. Here is list of my steps:

1. Create Sphere source and apply Elevation Filter onto it,
2. File->Export, select WEBGL Files (*.webgl) file type and push OK button.

I tested on Windows 10 Pro x64, but, also, have confirmation it occurs
under Windows 7 x64. Btw, it also occurs on ParaView v5.4.0.

Does anyone have any idea?

Best regards,
Nenad.

[Paraview] SWKey: Way to Enlarge Upper Left Display Panel Icons for Picking Points and Cells?

[Samuel Key]

Hi,

I am using PV V5.4.1 64bit on MS Windows 7 Pro.

My display has a resolution 2560 x 1440. I have located the 
Edit>Settings...>Tab:General and selected the 'Override Font option.' I 
moved it from 8 to 9. Nice! For my eyes, it is a big improvement.


However, when it comes to the Upper-Left display panel icons for Picking 
Points and Cells, I either need to use the pop-up hint for the buttons 
or get at least within 12 inches of the screen with my bi-focal 
eyeglasses to see clearly the icon representing the button's function. 
(By the way, the icons are excellent representations of the button 
function.)


Is there a way to enlarge this particular button bar to obtain slightly 
larger icons?


Thanks in advance for the bother,

Re: [Paraview] Paraview Simple Superquadric

[Mathieu Westphal]

Hello

you could use Glyph with custom source, but your superquadrics will not get
parametarized the way you want.
There is no direct way to do that, it could be done with a rather
complicated programmable python filter, wich would
create the superquadric and configurate them for each of your tensors.

Re: [Paraview] server-side InvokeEvent(...) doesn't call client-side observer

[Kolja Petersen]

Can anybody answer my question?
When Catalyst receives the next timestep update from some simulation every
few seconds or minutes, it sends its data to the pvserver process. The
pvserver somehow notifies the Paraview client, which will display the new
data.
If Utkarsh's comment is correct that no events can be forwarded from server
to client, then how does Paraview know that it should display the next
timestep?

I need to implement a very similar use case, for which a better
understanding of the communication between the Catalyst session, the
pvserver and the Paraview client is of high importance.
Thanks
Kolja

Re: [Paraview] Filter for deformation

Teng--

In my experience, using the WARP filter with a scale value of 1.0 on the 
displacement vector will give the actual distorted mesh at the time step, or 
load step being examined by ParaView.

If you are seeing "mesh overlaps" with the WARP filter as described above, then 
it is likely one of several conditions:

(1) The simulation datum set already contains the deformed mesh at each 
time/state-of-loading. (Check with whomever wrote the results output routine in 
your software.)

(2) The loads specified are larger than the structure can properly support,

(3) The simulation software may contain contact (aka sliding interface)

Re: [Paraview] Filter for deformation

[Samuel Key]

Teng--

In my experience, using the WARP filter with a scale value of 1.0 on the 
displacement vector will give the actual distorted mesh at the time 
step, or load step being examined by ParaView.


If you are seeing "mesh overlaps" with the WARP filter as described 
above, then it is likely one of several conditions:


(1) The simulation datum set already contains the deformed mesh at each 
time/state-of-loading. (Check with whomever wrote the results output 
routine in your software.)


(2) The loads specified are larger than the structure can properly support,

(3) The simulation software may contain contact (aka sliding interface) 
capability that is not being used or improperly specified,

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)

Hi  Andrew,

Would you try to apply the set of filters with Smooth, Subdivide and
Mask Points to a slice surface? The smoothing process helps to secure
an evenly distribution of points on a slice.

Thanks

[Paraview] Filter for deformation

[Li, Teng]

Hi all,

Can anyone tell me how to see the deformed shape? Right now, I can use wrap 
filter to magnify the displacement. But if I the magnified factor is too small, 
I can't see the small deformation. However, if I use much a bigger factor, the 
deformation will be too big that the mesh elements will have some overlap. So I 
wander which filter I can use to see the deformation directly.

Best,
Teng

Re: [Paraview] Fwd: OpenGL version

[Ken Martin]

All versions of paraview should work with OpenGL 4.1 so that error message
is really odd. Given that updating the driver fixes the issue, it could be
a driver bug. How old is the driver that is working with your other monitor?

[Paraview] Fwd: OpenGL version

[Devang Chauhan]

Hi All,

Can someone please recommend me version of Paraview that can work with
OpenGL version 4.1.0? In order to address this myself, I have been
downloading and testing older versions. I went down to paraview version
5.0.

Updating the graphic driver is one of the solutions and it works but doing
that unfortunately creates issues with two monitors I attach to my laptop
PC. So I would like to stick with this OpenGL version please.

If somebody can help me identify the compatible version that would be a
great help. I also attached the error I receive when I start paraview.

[Paraview] server-side InvokeEvent(...) doesn't call client-side observer

[Kolja Petersen]

Hello,
I would like to invoke a callback on a proxy in a pvpython session from a
server-side method.

In my server-side class "vtkCustom" I have a method
void vtkCustom::SetData(int i){
  ...
  this->InvokeEvent(1999,NULL);
  ...
}


On the client side, I create a proxy to a vtkCustom object, register an
observer and set the "Data" property, which should invoke eventid=1999:
...
custom=pxm.NewProxy("myextensions","Custom")
pxm.RegisterProxy("myextensions","Custom",custom)

def fun(obj,event):
  print "CALLBACK",obj,event

custom.AddObserver(1999,fun)
vtk.vtkSMPropertyHelper(custom.GetProperty("Data")).Set(42)
...

The observer function "fun" on the client is never invoked, although the
server-side invokes that event. I'm misunderstanding some concept of
Paraviews event mechanism for sure. Can you help me correct my steps?
Thanks
Kolja

Unrelated to your question, but you may want to upgrade to PV 5.4.1.  It’s

Hello,
I am working in a reduced unit system where the computed strain fields are

but that would increase my computational time.
Is there a way to turn off the automatic warping that ParaView performs on 
disp_k (k =x, y, z) fields?
I tried to use the WarpByVector filter with scale of 0.1 or smaller and that 
did not seem to work properly. I should mention I'm on version 5.0 (my favorite 
for a variety of reasons), so maybe the this WarpByVector issue is resolved in 
newer versions.

Re: [Paraview] Disable automatic mesh warping

[Moreland, Kenneth]

John,

Sam’s advice is sound, but I am curious where your data is coming from. 
ParaView usually does not automatically apply displacements by warping. The 
only exception I know of is the Exodus II reader, and in that case you can turn 
off the warping by unchecking the Apply Displacements checkbox.

Otherwise, it might be that the displacements are already applied in your data 
file. In which case Sam’s suggestion for undoing them with a negative warp 
should do the trick.

I tried to use the WarpByVector filter with scale of 0.1 or smaller 
and that did not seem to work properly. I should mention I'm on 
version 5.0 (my favorite for a variety of reasons), so maybe the this 
WarpByVector issue is resolved in newer versions.

[Paraview] Defining DataItem attribute "Dimensions" as an element is not working

[Marco Lucchesi]

Hi folks,

I am new to XML and therefore I am killing myself with making XDMF files
working. I have a (working) XDMF that contains a  looking like:


  
  grid.h5:/x_grid
  
...


I am a bit annoyed by the static definition of the attribute "Dimensions",
that I would naively define as an element:


  
   200 
  grid.h5:/x_grid
  
...


such that, later on, I could use an  to import the value from
an external source, and use an XPath to define the element Dimensions.
However, Paraview does not like this second version, giving me errors like:

ERROR: In
/home/kitware/Dashboards/MyTests/NightlyMaster/ParaViewSuperbuild-Release/paraview/src/paraview/VTK/IO/Xdmf2/vtkXdmfReader.cxx,
line 409
vtkXdmfReader (0x36249d0): Failed to read data.

Now, I am new to XML, so I could have misunderstood the relation between
attributes and elements.
Would you please advise me about this issue? Or, do you know a better
strategy to dynamically import geometries?

Many thanks,

Marco

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)

Hi Samuel,

Thank you so much! This is extremely helpful ^_^

Subject: Re: [Paraview] Degrees of freedom


Doina--


In what follows, I will skip talking about a 3-nod quadratic line as a way to 
display a cured beam or a deformed beam. (I live in a world of large 
deformation simulations and I like to display that type of behavior.)


The concept of FIELD (aka GLOBAL) simulation results, for example, results that 
come from or related to overall behavior like total Kinetic Energy (KE), are 
well supported by the Exodus-II format and are absent from the EnSight format 
and the VTK format for simulation results. I will confine my comments to what I 
have to offer to just POINT data and CELL data.


It is convenient to divide simulation results into three categories for 
virtually all of the data formats that PV can read.

(1) GEOMETRY data

(2) POINT data

(3) CELL data


The following is the VTK-XML ASCII format. (See the attached file 
'resultsvtk.f')


(1) GEOMETRY. ParaView is quite happy with just GEOMETRY data.(It is a nice way 
to start when one is trying to write a datum set for ParaView. ParaView will 
display an object with only the geometry data.)


(1a) Write the entire Point inventory from 1 to n where n = number of nodal 
points  in terms of coordinate 3-tuples [(x1,y1,z1,), ...,(xn,yn,zn)]


(1b) Write the entire Cell inventory of connectivity n-tuples (as array 
offsets!)

(1c) Write the 'starting location' for the n-tuples in (1b)

(1d) Write the VTK cell-type values for the n-tuples in (1b)


ParaView now has everything it needs to display your geometry.


(2) Write POINT data information.

(2a) In the case of 'mode shapes,' write the mode's displacement 3-tuples (aka 
Vectors, name="Mode1")

[(UxM1,UyM1,UzM1),...,(UxMn,UyMn,UzMn)]

(2b) Repeat with name="Mode2", and so fourth (aka und so weiter)


ParaView now has the enough information to animate the mode shapes. 
Instructions are here

( https://public.kitware.com/pipermail/paraview/2017-October/041077.html ) for 
producing animations of the mode shapes.


Hope this helps.

At the risk of underestimating ParaView's functionalities, I can tell you what 
will work. For displaying geometry,  PV only needs Point (aka nodal point) 
x,y,z-coordinates, a Cell (aka Finite Element, ...)  type  and for each Cell an 
n-tuple of Point "array locations", for example, EnSight-format::{1,2,4,3,7,8,} 
or VTK-format::{0,1,3,2,6,7}.


The VTK format uses C-language 'array offsets' for Cell connectivity n-tuples. 
The EnSight format uses FORTRAN-language array locations for Finite Element 
connectivity n-tuples. It is just the way it is.


Variables are either located at Points or in Cells (conceptually Cell centers). 
The arrays supplied for variables must span all of the Points or all of the 
Cells. (I do not know how to use or about the acceptability of "partially" 
specified variable datum sets.) For Points with 6-DOFs versus 3-DOFs, if you 
want to see the three rotational DOFs, use POINT DATA arrays and fill in the 
Phi-x, Phi-y, Phi-z values using zeros for at those Points without a rotation.


If you want to visually display a 2-node, 6-DOF beam's geometry (a curved beam 
or a deformed beam) , one solution is too use a VTK Cell type 
'VTK_QUADRATIC_EDGE = 21'  for the beam. This will require you to 
add-on-the-fly to the simulation results a beam center-Point with 
x,y,z-coordinates and displacements for the beam's center Point using the 
beam's interpolation functions. (PV has a Warp Filter that will let you then 
scale up the deflections for visualization purposes.)


Should you have access to source code for the simulations, I can supply FORTRAN 
language routines that write VTK ASCII-formatted simulation results. (My 
personal preference is the EnSight format.)

[Paraview] Python programmable filter to process results over time

[Messner, Mark Christian]

I'm trying to make a programmable filter to do some post-processing that 
involves accumulating data from multiple time steps.


This isn't really what I'm trying to do but as an example of something that 
would get me most of the way there say I want to sum up the values of a field 
over a range of time steps and then display that cumulative sum as a field 
itself.


My googling seems to indicate this is now possible with the programmable filter 
but hasn't turned up any simple example of how to do it.  Does someone have 
such an example or can someone point me in the right direction on how to do 
this (if it's indeed possible)?


Thanks,


Mark

[Paraview] Displaying volume outside of mesh as solid

[sergey]

Hello,

I am looking for a way to display a volume that is not covered by mesh
(its located somewhere in the middle of mesh).

By default such volumes (without mesh) are shown as empty area, and
meshed area is shown as solid.

I need to reverse the solid and empty areas, so that non-meshed volume
is shown as solid, and meshed volume as empty.

Mesh is in 3D.

Is there a way to do this?

Thank you very much.

Best,

Sergey

Re: [Paraview] boolean mesh filtering

[TJ Corona]

Hi Jeffrey,

You may want to check out vtkBooleanOperationPolyDataFilter 
.
 It sounds like it may have the functionality you desire.

[Paraview] boolean mesh filtering

[Mauldin, Jeffrey A.]

I have a need to do a Boolean intersection of two unstructured multiblock 
datasets.  It so happens in this case that the underlying element sets are 
polygonal meshes, so in this particular case I could also do what I want with a 
Boolean intersection of two polygonal meshes.  To be (hopefully) redundant, I 
have two meshes which share some points and cells and each of which have other 
points and cells which are not shared.  I would like a new mesh which consists 
of all the points and cells that are in both of these meshes.  I need this to 
work properly in parallel.

I know enough to create a python-based filter (python programmable filter) to 
create this operation, but are there already existing Boolean mesh operations, 
and if not would those be a useful thing to add?

I tried reading them with XDMF 3 reader and it works fine.

Thank you for the suggestions.

Re: [Paraview] Error reading timeseries with spatial grid collection with XDMF

[David E DeMarle]

It might be that the reader doesn't like or want that both of your times
are 0.0.
...

...

...
but your third case doesn't fit that hypothesis.

Otherwise your file looks ok at first glance. I'ld have to debug the reader
on your data to figure out what is going wrong.

Re: [Paraview] SWKey: File extension for PV Readers?

[David E DeMarle]

Not yet.

You could add one by editing the appropriate "ReaderFactory extensions"...
line of ParaviewCore/ServerManager/SMApplication/Resource/proxies_xdmf3.xml
in your builds.

Re: [Paraview] Good file format for point data on a surface over 60, 000 timesteps

[Tyson Whitehead]

On 20/11/17 12:49 PM, Berk Geveci wrote:

What kind of visualizations are they looking to do? It may be a good idea to 
treat time differently here given that it is the most dense dimensions. I am 
thinking of some sort of tabular format that can then be used with filtering to 
extract a time step. Potentially, even a database may work depending on what 
the end visualization product will be.


My understanding is they want to start by making a movie of the recorded 
pressure values interpolated (as some color ramp) across the structure surface 
and as this is what they are currently doing with their MATLAB code.

I ultimately expect they may come up with something else once they get the data 
in though and are able to play around with it (enabling playing around with it 
being a big part of why they are wanting to get it into ParaView).

While the local expert, I've only really go very very basic experience so far 
(all I've really done is work through the various tutorials and teach them in 
workshops), so I'm interested in any advice.

Compared to the tutorials, the strange thing about this data is the large 
number of time steps, that it is spatially irregular and sparse, and that it 
doesn't fully define the underlying object geometry (i.e., the geometry of the 
surface extends out past the last sample points due to each measurement point 
requiring drilling holes for measurement taps in the physical object).

Currently I'm think, if we can come up with a decent way of importing the data 
as a point set, of

https://blog.kitware.com/dataset-resampling-filters/

1. import the sample data as a point data set
2. use the point volume interpolate (or resample to image?) to create a mesh 
from it
3. use the re-sample with dataset to put that onto the actual physical geometery
4. save animation to get the desired movie

Is there a better way to do this?  Should I try and create some sort of 
irregular grid out of the sample data to avoid step 2?

Thanks!  -Tyson

Re: [Paraview] paraview osmesa render on supercomputer nodes

[程迪]

Yes, the network environment in TianHe-2 is weird.

However, the problem can be solved manually by set ssh port forwarding like
this:

1. start pvserver on cn123 in direct connection mode and let it listen to
port 1
2. manually modify the local port forward in my PC as: -L1::1
3. use paraview gui in my PC to connect to localhost:1

I think it makes sense.

Re: [Paraview] Good file format for point data on a surface over 60, 000 timesteps

[Berk Geveci]

What kind of visualizations are they looking to do? It may be a good idea
to treat time differently here given that it is the most dense dimensions.
I am thinking of some sort of tabular format that can then be used with
filtering to extract a time step. Potentially, even a database may work
depending on what the end visualization product will be.

Re: [Paraview] paraview osmesa render on supercomputer nodes

[David E DeMarle]

---

This syntax isn't clear to me:
> srun -n 24 pvserver -sp=15801 --mesa --use-offscreen-rendering
--disable-xdisplay-test
---ssh -N -f -L15801:localhost:15801 though internal connection-->
Where are you trying to run ssh on to open up this second (between login
and compute) tunnel?

---
ERROR: In /HOME/pp569/soft/ParaView-v5.4.1/VTK/Common/System/vtkSocket.cxx,
line 206
vtkServerSocket (0x20e9c20): Socket error in call to bind. Address already
in use.

Indicates that pvserver is trying to grab a socket that some other process
owns. You might be competing with one of your other pvserver processes
(from an earlier run or perhaps a misconfigured non-mpi pvserver task
running on the same node from this srun invocation) or possibly your ssh
tunnel process.

---

Forward connections from desktop to login to compute are harder to setup in
most cases because in general you don't know what compute node (and
sometimes login node) you will get.

---

I recommend using something simple like netcat to send and receive messages
across each tunnel. If you can type on one side and see the text on the
other, then paraview should be able to use the connection.

Please let us know how it goes. We would love to see ParaView running on

[Paraview] Degrees of freedom

[Doina Gumeniuc (224252 MAHS)]

Hi all!

I am still learning the use of paraview and I have got to such a question: How 
to show in a vtk input file the degrees of freedom of elements? Some of the 
beams have 6 degrees of freedom, some of the other elements...less or nothing 
at all. IS there any possibility?

Thank you a lot in advance!

[Paraview] paraview osmesa render on supercomputer nodes

[程迪]

Hi everyone,

I just compiled the OSMesa version of paraview 5.4.1 on Tianhe-2
supercomputer. My trouble is to connect the pvserver running on computing
nodes while I am on login node with ssh tunnelling (-L).

Here is what I did

My computer (win7 64 bit)
---ssh -L15801:localhost:15801 through VPN--->
LN31 (login node, RHEL maybe, using slurm)
> srun -n 24 pvserver -sp=15801 --mesa --use-offscreen-rendering
--disable-xdisplay-test
---ssh -N -f -L15801:localhost:15801 though internal connection-->
CN (computing node)

And here is the error:

```
Waiting for client...
Connection URL: cs://cn10687:15801
ERROR: In /HOME/pp569/soft/ParaView-v5.4.1/VTK/Common/System/vtkSocket.cxx,
line 206
vtkServerSocket (0x20e9c20): Socket error in call to bind. Address already
in use.

ERROR: In
/HOME/pp569/soft/ParaView-v5.4.1/ParaViewCore/ClientServerCore/Core/vtkTCPNetworkAccessManager.cxx,
line 349
vtkTCPNetworkAccessManager (0x14ad080): Failed to set up server socket.

Exiting...
```

It seems not working. I am pretty sure that the PC -- ssh -L through VPN
--> LN works well. What happend in LN -- ssh -L --> CNxxx link?

I have searched the internet for something, I found that LLNL did some work
on it [
https://hpc.llnl.gov/data-vis/vis-software/paraview/running-paraview-in-client-server-mode
].

They used `ssh -R` to map from LN to CN, rather than `ssh -L` and run
paraview in RC mode, does it make any sense?

However, in Tianhe-2, the `ssh -R` is forbidden. So I cannot use this
method.

Re: [Paraview] Anaconda python Environment setup to use paraview python

[Schau, Kyle A]

Ke

I have not had luck with anaconda and utilizing paraview python tools. The 
problems comes from compilation options. To run the paraview modules the python 
you are using needs to be compiled with the option --enable-unicode set at 
compile time. The python that ships with Anaconda does not come with this. 
Specifically, I think that for ParaView versions > 5 you need to enable 
universal character set 4 for everything to work. I use PV 4.4 with a self 
built python 2.7.13 and the only compile option -enable-Unicode and it works 
great.

has a nice feature that every variable has its own file. So, each 
'sample point' will have its own file. The file names can be as you 
want, numeric or alphabetic. The EnSight format has a geometry file, but 
if you want to use single vertex cells it won't become very large.  If 
you want to be a little more graphical, you could use 64 4-node quads 
with their respective coordinate positions. Additionally, you could add 
a relatively coarse mesh of the structure. (ParaView has a Filter that 
will take a point set (your 64 single-point cells) and construct a 
triangular mesh to provide some geometry.


The EnSight format uses a meta-file (aka *.case file) that references 
all of the files in the datum set, example attached. It will be some 
work the first time around, but well worth it in my opinion.


(I use this file-format myself for million-element 3-D meshes for 
transient dynamic simulations. I would not leave home without it.)

Hi,

I'm trying to help one of our users (HPC center) use ParaView to work
with their wind tunnel data.  They have a large number of time samples
(60,000) from a series of surfaces with from a small number of sample
points (64).

The sample points are irregular but structured as they are laid out to
be more dense in areas that should see more differences (i.e., at best
you could say it was a non-uniform grid with several of the points not
used).

What file format should this data be put in to import into ParaView?

The VTK legacy formats and XML description formats seem painful to use
with this number of timesteps and I believe (please correct if wrong)
that the NetCDF wants a regular grid.

Thanks!  -Tyson

[Paraview] Good file format for point data on a surface over 60, 000 timesteps

[Tyson Whitehead]

Hi,

I'm trying to help one of our users (HPC center) use ParaView to work
with their wind tunnel data.  They have a large number of time samples
(60,000) from a series of surfaces with from a small number of sample
points (64).

The sample points are irregular but structured as they are laid out to
be more dense in areas that should see more differences (i.e., at best
you could say it was a non-uniform grid with several of the points not
used).

What file format should this data be put in to import into ParaView?

The VTK legacy formats and XML description formats seem painful to use
with this number of timesteps and I believe (please correct if wrong)
that the NetCDF wants a regular grid.

Thanks!  -Tyson

builds, or Kitware binaries?  I am using 5.4.1 Kitware binaries, local server.  
If not, try Kitware binaries?

Alan,

Version 5.4.1,   Redhat, can.ex2

I tried deleting my PV ini files in hopes that would fix it, but no joy!

I’m getting the same msg I was getting in v4.4 (but in v4.4 it still produced a

[Paraview] Anaconda python Environment setup to use paraview python

[Ke Gao]

Hi,

I'm using Anaconda python 2.7 to call paraview python library on RedHat
Linux, every time I run "from paraview.simple import *" or '"from vtk
import *", I will get a "Segmentation fault" error. Can anybody tell me
what's wrong, and can you share your python path setup in .bashre file?

My .bashrc file is like this:

# add paraview
export

# add paraview python to PYTHONPATH

Re: [Paraview] [EXTERNAL] Re: pvbatch

[Scott, W Alan]

OK, this … sort of  … worked.  I was able to use the Kitware download (Yay!).  
I called pvbatch (surprisingly, it was built by Kitware for Linux), and then 
used flags --mesa-llvm and --use-offscreen-rendering.  I believe 
--use-offscreen-rendering will be replaced in the future by 
--force-offscreen-rendering in PV 5.5.0.

Thanks Cory, and everyone else that chimed in.

Alan,

You should be able to run

pvpython --force-offscreen-rendering script.py

and no render window will appear. The help for --force-offscreen-rendering says:

  "If supported by the build and platform, create headless (offscreen) render 
windows for rendering results."

I believe this should work on linux systems, but you should try it out on the 
system on which you want to force offscreen rendering just to be sure before 
using it to produce classified images.

pvbatch running the same script will indeed not pop up a render window even 
without the --force-offscreen-rendering option.

Let us know how it goes,
Cory

I believe this is a change from the past.  Here is what I desire – how do I get

I want to run pv(pythonScript).  I want it to produce output.  I want it to run 
off screen, not showing on the console display or current display.  This is 
especially important on classified systems.  MPI is not available.

Not too long ago, my understanding was this was pvbatch.  pvpython used either 
the console display or current display as it’s rendering space.  This does not 
catch my needs.

pvpython is the non-MPI version of pvbatch. The superbuild docs could
probably be improved here. Currently, the mention is:

ParaView supports multiple rendering engines including `egl`,
`mesa`, `osmesa`, and `qt5`. All of these are incompatible with each
other. If none of these are chosen, a UI-less ParaView will be built
(basically just `pvpython`). On Windows and macOS, only the `qt5`
rendering engine is available.

[Paraview] Structured meshes with Material Volume Fractions

[Scott, W Alan]

Does anyone have a very small dataset that is structured meshes, that use 
multiple material volume fractions?

Also, are we missing a functionality processing these datsets?  In other words, 
do we need a filter that will contour over many material volume fractions 
within the same filter?

Thanks,

Alan

[Paraview] XDMF file with multiple temporal collections

[Nicolas Cedilnik]

Hello all,

I'm trying to generate a valid (at least, well-read by paraview) XDMF 
file. It represents a single topology/geometry, with multiple scalars, 
varying over time.


I've attached the file I'm trying to read with paraview. It behaves 
almost as I want, but oddly enough, only with scalars tagged as 
"partial" by paraview.


One of the scalars "animation", the first one in the XDMF file, is 
completely buggy, possibly with values from other scalars.


Is there something wrong with my XDMF file or is this a bug in paraview?

Thanks for your help,

-- Nicolas

[Paraview] vtkDiscreteMarchingCubes point/cell arrays from XML-PV plugin

[Grothausmann, Roman Dr.]

Dear mailing list members,


Based on AcceleratedAlgorithms.xml I created an XML-PV plugin to make use of
vtkDiscreteMarchingCubes 
(https://github.com/romangrothausmann/ParaView_XML-plugins/blob/1574430ce/vtkDiscreteMarchingCubes.xml). 
It basically works as expected, but does not yield any point/cell arrays in its 
result, that I would need for coloring of e.g. the different labels (i.e. 
ComputeScalars). I found a post that said that PV only lists arrays that have a 
name, but as far as I understand, vtkDiscreteMarchingCubes does name its output 
arrays.

What else could be missing in the XML-code?

Many thanks for any help or hints.
Roman

On startup, Qt makes a context without a profile. Mesa gives it the best
compatibility profile it can: 2.0. Qt then interprets this as the
highest OpenGL version available and clamps all requests to this
version. The entire behavior is mystifying to me, but the issue has been
filed here:

[Paraview] Viewing Delft3D output in ParaView

[Ahmed Bilal]

Hello Everyone.
Is there a way to see Delft 3D output in ParaView. Delft 3D produces its
outout in  NFIES compliant (*.dat) format. Any plugin to directly view
these files. Or any way to convert these files into NetCDF for viewing in
ParaView.

Thanks in advance.

with the gpu_shader4 extension is not supported by your graphics
driver but is required for the new OpenGL rendering backend.
Please update your OpenGL driver. If you are using Mesa please
make sure you have version 10.6.5 or later and make sure your
driver in Mesa supports OpenGL 3.2.

Re: [Paraview] How to read the file info in *pvd file

[Ke Gao]

Actually, what I want to do is using python script to read *pvd file first
to get the name info of *pvtu files. Then use the *pvtu file name to read
through all of them one by one to extract the info I want. I'm not sure if
there is a better way to realize this.

Many thanks.

Re: [Paraview] How to read the file info in *pvd file

[Cory Quammen]

The file names are embedded in the same XML element as the time step:



But I'll be that's not how you want to access them.

Next question: From where do you want to access the file names? A Python
script? In the UI?

Re: [Paraview] GoCAD and Earth Vision grid files *.ts & *.evgd

[Aashish Chaudhary]

the code I pointed to is based on a older version of the VTK and ParaView
and needs to be ported to newer VTK and ParaView. I do not expect it will
be lot of work but some work and we can help you over the email if needed.

Thanks

Re: [Paraview] GoCAD and Earth Vision grid files *.ts & *.evgd

[Sonya Davydycheva]

Thank you Aashish,

But the link you provided includes:

   - GoCad ASCII Files (*.gp, *.ts, *.pl, *.vs, *.vts, *.vo, *.sg)

(see Bottom of Supported Readers).
Does it mean GoCAD files are doable already? Or, something still needs to
be added to Paraview, to read them?

[Paraview] Animation .avi output not working in v5.4.1, working in v4.4

[Dennis Conklin]

Anyone else seeing this?

I'm getting the same msg I was getting in v4.4 (but in v4.4 it still produced a 
useable animation).


[avi @ 0x8ec35c0] Using AVStream.codec.time_base as a timebase hint to the 
muxer is deprecated. Set AVStream.time_base instead.
[avi @ 0x8ec35c0] Encoder did not produce proper pts, making some up.

the actual code location is here:

Let us know if you decide to bring in this code into VTK / ParaView as we

Re: [Paraview] [EXTERNAL] Re: pvbatch

[Cory Quammen]

Alan,

You should be able to run

pvpython --force-offscreen-rendering script.py

and no render window will appear. The help for --force-offscreen-rendering
says:

  "If supported by the build and platform, create headless (offscreen)
render windows for rendering results."

I believe this should work on linux systems, but you should try it out on
the system on which you want to force offscreen rendering just to be sure
before using it to produce classified images.

pvbatch running the same script will indeed not pop up a render window even
without the --force-offscreen-rendering option.

Let us know how it goes,
Cory

Re: [Paraview] GoCAD and Earth Vision grid files *.ts & *.evgd

[Aashish Chaudhary]

I do not think that GoCAR ASCII (ts) files are directly readable in
ParaView. Although there is a reader in this repo
http://paraviewgeo.objectivity.ca/documentation/user-manual/supported-formats
that
you could bring into ParaView / VTK. If that is the case, we would be happy
to help bringing in the reader in VTK / ParaView.

thanks

Re: [Paraview] How to read the file info in *pvd file

[Ke Gao]

Hi,

I mean how to get the file name info such as "Sout_1012.pvtu",
"Sout_1013.pvtu". Currently I can only read the timestep info such as
"+1.9880e+03".

Many thanks.

Re: [Paraview] How to read the file info in *pvd file

[Cory Quammen]

What do you mean by "file info"? File name? Size of the file? Data arrays
in the file?

Re: [Paraview] OpenGL inside VMWare virtual machine

[Ken Martin]

This could  be a PV Qt interaction. Try setting MESA_GL_VERSION_OVERRIDE=3.2
in your environment

Basically there is a bug in Qt on windows where it refuses to see the 3.2
context from Mesa because it is not a compatibility context.

Re: [Paraview] [EXT] Re: Exodus multiblock dataset block numbers vs block

[Dennis Conklin]

Shawn,

I grok the origin of the non-intuitive, better omitted than displayed, highly 
confusing, should be replaced with block names, block numbers.However, in 
my Programmable filter I just have a single block and I need the index into the 
block name – I’m not sure it exists anywhere that I can access.

Dennis

 WARNING - External email; exercise caution.



Hi Dennis,
I can answer part of your question.  The block number is the index in a 
pre-order traversal of the tree of blocks in the dataset.  The root is element 
0, its first child is 1, that block's first child (or if none, the root's 
second child) is 2 and so on.  Your blocks with data are likely two levels down 
since your index has that offset (and your code backs this up since you are 
asking for the metadata of a child of the root's block 0).
HTH,
Shawn

All,

Okay, maybe not the clearest email I’ve ever written!

See the attached image:  Here I have loaded a single block out of a multi-block 
dataset.

It is the 24th block in the dataset.
It was assigned the block_ID 101 at creation (we separate different blocks into 
different number ranges)
So, it is shown in the Spreadsheet view as Block Number 25 (24+1)

However, I need the Block_Name of this block.   The block name is stored under:
Input.GetBlock(0).GetMetaData(23).Get(vtk.vtkCompositeDataSet.NAME())
   (23=24-1)

In order to retrieve the name, I need to find the Block Number 25 (and subtract 
2 from it).

I have been unable to find this block_number.I can’t count blocks to find 
out the block_number, because my Programmable filter only has this 1 block in 
it.

So, does anyone know where this “Block Number” is stored?I’m wishing at 
this point that the Exodus reader had stored the block names in a dictionary 
with BlockID (ObjectID) as the key – then I could find  the name.

Any clues on how to determine the Block Number?

Thanks
Dennis
