[Paraview] PV 3.6.2 and VisIt Plugin: crash when loading state with Tecplot files

[Richard GRENON]

Hello.

PV 3.6.2 crashes on Linux when loading a state file (*.pvsm) that 
references Tecplot files.


Here is my test:

-Starting PV 3.6.2 (Linux), I load the VisIt plugin.
-I open two 3D IJK ordered Tecplot files (*.tp). No problem (PV freezes 
while loading the files, but I can continue after the files are loaded).
-I extract the J=1 surface for each file, I group the two extracted 
surface and I color this new dataset with one variable.

-I save the state of my work in a *.pvsm file.
-I disconnect to clear all data.
-I try to load the saved pvsm file. PV freezes as it does while opening 
Tecplot files, then it crashes!
The same crash happens when I try to load the state file after 
restarting PV and reloading the VisIt plugin.


Has anyone an idea?

Best regards.

[Paraview] Info about installing ParaView 3.6.2 on RedHat Enterprise

[bassaidai]

Hi,
we installed ParaView 3.6.2 only on Linux Debian and, as explained here
http://paraview.org/Wiki/ParaView:Build_And_Install#Build_ParaView, we
installed the additional .deb packages required (mpi, qt4, python...).

But if we would install ParaView 3.6.2 on Linux RedHat Enterprise, should we
install any .rpm additional packages?

Thank you very much
Luis

[Paraview] PV 3.6.2 and VisIt Plugin: crash when loading state with Tecplot files

[Richard GRENON]

Hello.

I have made an additional test: grouping all tecplot files in a same 
dataset before any other operation allows to use the saved state file.


Test 1: the simple pipeline that cannot be used as saved state:
- open Tecplot File 1
   |
   extract subset 1
- open Tecplot File 2
   |
   extract subset 2
- group subset 1 and subset 2 in new dataset 1
- coloring the dataset 1

Saving state of this pipeline, loading the pvsm file crashes PV.

Test 2: the more complex pipeline that can be used as a saved state:
- Open Tecplot File 1
- Open Tecplot File 2
- group loaded Tecplot Files 1 and 2 in new dataset 1
  |
  extract block 1 from dataset 1 (content of Tecplot file 1)
  extract subset 1 from bloc 1
  |
  extract block 2 from dataset 1 (content of Tecplot file 2)
  extract subset 2 from block 2
- group subset 1 and subset 2 in dataset 2
- coloring the dataset 2

Saving state of this pipeline, the pvsm file can be used.
Note: After loading the pvsm file, you must go on the reader of each 
tecplot file, select the arrays (unselected by default), then click apply.


Of course, I can attach the two corresponding pvsm files if it may help.

Best regards

Hi Richard, please do. I will try running your steps with a debug build and
see if I can track down the crash.

Re: [Paraview] PV 3.6.2 and VisIt Plugin: crash when loading state with Tecplot files

[Richard GRENON]

Hi Dave.

I attached a tar gzipped file that contains the two pvsm files:
essaipv01.pvsm : state file of Test 1, crashes PV.
essaipv02.pvsm : state file of Test 2, OK.

I can't send my two formatted Tecplot files (too big) but I think you 
can easily rebuild them with any data from the headers below.

Each file is a formatted Tecplot file with name ending with ".tp"
There is only one zone (block) per file.
Each zone is a 3D IJK ordered grid with coordinates x,y,z and some other 
scalar arrays (pressure, temperature, etc...)
Following are the file headers where you will find the dimensions of the 
grids and the variables:


- File 1:
TITLE = "E_Fld0001_RAPRO2_F06_M020"
VARIABLES = "x" "y" "z" "vx" "vy" "vz" "M" "p" "Pi" "rok" "viscrapp" 
"ro" "tsta" "tgen"

ZONE T="Window(s) : Dom0001",  I=181,  J=9,  K=97, F=BLOCK

-File 2:
TITLE = "E_Fld0002_RAPRO2_F06_M020"
VARIABLES = "x" "y" "z" "vx" "vy" "vz" "M" "p" "Pi" "rok" "viscrapp" 
"ro" "tsta" "tgen"

ZONE T="Window(s) : Dom0002",  I=61,  J=9,  K=25, F=BLOCK

Best regards,

Richard

[Paraview] time evolution not working when using EnsightMaster

[Ricardo Reis]

 I've got a set of data partioned in ensight and I am using the 
EnsightMaster Server files.


 If I open just part of the set (one of the case files) I can march in 
time without any problem.


 If I launch pvserver as a mpi process the time marching is not working. 
It keeps the same data and time evolves from


 0.0 to 0. to 0. to 0. ...

 I also get this error in the xterm of the pvserver machine:

 Process id: 0 >> ERROR: In
/home/rreis/src/ParaView3/Servers/Filters/vtkPVEnSightMasterServerReader.cxx,

[Paraview] X Error: BadLength on OpenSUSE11.2

[Robert Sawko]

Dear All,

I was getting acquainted with ParaView features via tutorials but
suddenly my education was interrupted with a X Error. Whilst doing a
tutorial 2.8 from the 3.6 Version of The ParaView Tutorial and upon
clicking Volume Representation I am being propmpted with the following
message:

X Error: BadLength (poly request too large or internal Xlib length error) 16
  Extension:135 (Uknown extension)
  Minor opcode: 1 (Unknown request)
  Resource id:  0x5a002cc

And also:
paraview: xcb_io.c:176: process_responses: Assertion `!(req &&
current_request && !(((long) (req->sequence) - (long)
(current_request)) <= 0))' failed.
Aborted

Then ParaView crashes.

I am running  OpenSUSE 11.2 with KDE 4.3.1. My Qt library bears a
number 4.5.3. If anybody encountered similar issued I would earnestly
ask for some assistance.

Many thanks,
Robert

Re: [Paraview] vtkSMProxy::GetProperty gives segmentation fault

[Erik Rasmussen]

I wish I could have understood this issue.  I tested a variety of 
things, examined my executable with ldd, tried various cmake variable 
changes.  The problem persisted until I got rid of the ParaView 3.6.2 
distribution, downloaded it again, and built again.  That fixed the 
problem.  So I figured I would post this to the list in case any other 
unfortunate developer has the same problem.

I am working with a file-reading filter.  There are no error messages or
warnings when I compile.  After I build, I copy the filter .so files to the
bin/plugins location, where they are automatically detected by paraview.

When I choose the File, all goes well.  The usual RequestDataObject and
RequestInformation methods are executed.  All my debug output looks fine.

When I press the Apply button, I know that RequestData is messaged and it
seems to finish its work OK.

As an aside, my vtkDebugMacro output now only shows up in the gdb terminal
output; it stops going to the output messages window of Paraview.  I don't
know what that means, except that it seems to tell me that something is
going haywire near the start of RequestData, even though that method seems
to run fine.  (I suppose I'm not seeing it in the output messages window
because that window may be buffered?)

The actual crash seems to happen just about when ParaView would normally be
drawing an empty cube outline on the screen (the reader puts a rectilinear
grid into the pipeline).

In the traceback (below), it looks like ParaView is messaging vtkSMProxy
object that has not been instantiated... this=0x0

Has anyone seen this before?  Any suggestions on how to debug further?

Thanks,
Erik

Re: [Paraview] How to make movies using trajectory data of granular particles

[Moreland, Kenneth]

Hmm.  Sounds like there is something wrong with the format of your data or 
something is wrong with ParaView's reader or your data file is using some 
feature that ParaView's reader does not support.  At any rate, there is not 
enough information here to diagnose the problem.  It would help if you posted 
your data.  Hopefully someone on the list who knows more about the XYZ 
molecular data format can look into it.  (I have never used it.)

[Paraview] Peavip enables VTK filters and sources in ParaView

[Jérôme]

Dear all,

I launched a few months ago an initiative on github. This is called Peavip
and aims at
exposing VTK filters to the ParaView GUI.
The structure is as follow:
- each filter/source has its own XML description
(ServerManagerConfiguration)
  It allows for fast loading of particular filter, without having to build
something
- a CMakeLists gathers the XMLs in order to produce a cxx plugin
  The user can load all XMLized filters thanks to a single so/dll/dyn file.

This git repository is under development, and new features wil be added, I
hope, soon.
Coming next:
- Choice of exposed filters during the CMake setup
- Documentation!!
- Categorization of filters in the "Filters" menu from ParaView
- ... ideas from the community

You will find the Peavip git repository here:
http://github.com/jeromevelut/Peavip

Although this is a pre-alpha-Proof-of-concept-preliminar software,
I hope that it will be useful for people. Feel free to send feedbacks!

Best regards,
Jerome

Thanks. ssh wont work for me and using the proxy git fails at the same
large file than before.

Re: [Paraview] PV 3.6.2 and VisIt Plugin: crash when loading state with Tecplot files

[burlen]

Hi Richard and Dave,

I think that the way the VisIt plugin currently communicates information 
between client and server is not going to work with state.


The way it is now the plugin repeatedly sends variable length vectors of 
array,block,material ids,, etc one array for each mesh. Each of these 
might have a different size depending on the user's selections. In order 
to work around the fact that PV sm vector props don't support variable 
length vectors it also expects the array of mesh ids to be sent first, 
from this it sizes the other arrays to fit what will be incoming.


One solution would be to serialize the users selections in a single 
string, using sm string vector property to send server side. That would 
work with state. Otherwise I'm afraid your going to have to do some 
heavy sm programming.


I regret the way I did that, if it's helpful I'll volunteer to fix it.

Thanks for tracking this down!

Hello.

I have made an additional test: grouping all tecplot files in a
same dataset before any other operation allows to use the saved
state file.

Test 1: the simple pipeline that cannot be used as saved state:
- open Tecplot File 1
  |
  extract subset 1
- open Tecplot File 2
  |
  extract subset 2
- group subset 1 and subset 2 in new dataset 1
- coloring the dataset 1

Saving state of this pipeline, loading the pvsm file crashes PV.

Test 2: the more complex pipeline that can be used as a saved state:
- Open Tecplot File 1
- Open Tecplot File 2
- group loaded Tecplot Files 1 and 2 in new dataset 1
 |
 extract block 1 from dataset 1 (content of Tecplot file 1)
 extract subset 1 from bloc 1
 |
 extract block 2 from dataset 1 (content of Tecplot file 2)
 extract subset 2 from block 2
- group subset 1 and subset 2 in dataset 2
- coloring the dataset 2

Saving state of this pipeline, the pvsm file can be used.
Note: After loading the pvsm file, you must go on the reader of
each tecplot file, select the arrays (unselected by default), then
click apply.

Of course, I can attach the two corresponding pvsm files if it may
help.


Best regards

Re: [Paraview] Application using Paraview library in C++

[pat marion]

Hi,

You should include the exact error message you are getting so that people
can help.

I'm not very familiar with building custom apps using paraview so I won't be
able to answer your question exactly... but to change the representation to
volume you must create proxy objects for a lookup table and a piecewise
function, then assign them to the representation's proxy properties
LookupTable and ScalarOpacityFunction.

The best example I have is in python- a image-data source is created and the
representation is set to volume, the scalar value 37 is set to the color red
with an opacity value of 0, and scalar value 270 is set to the color blue
with opacity value 0.5:

Wavelet()
rep = Show()
rep.ColorArrayName = "RTData"
rep.Representation = "Volume"

lut = CreateLookupTable()
lut.RGBPoints = [37, 1, 0, 0, 270, 0, 0, 1]
rep.LookupTable = lut

func = CreatePiecewiseFunction()
func.Points = [37, 0, 270, 0.5]
rep.ScalarOpacityFunction = func

Render()


Goodluck!

Pat
