Re: [Paraview] Help :Texture coordinates

[David E DeMarle]

Adding the list back into the discussion so everyone can contribute to and
benefit from the discussion.

To the best of my knowledge we don't have anything that will do that type
of modelling yet. Presumably you could write a programmable filter that
would iterate over all of the cells, and use the cells orientation to make
up texture coordinates, duplicating point coordinates as needed. That will
be tricky.

You will likely have more success by exporting the model from ParaView into
a dedicated modelling/graphics package, generating the textures you want
there, and then reimporting the result back into ParaView.

The three Filters->Texture Map To ... filters programmatically create

Re: [Paraview] Help with ProgrammableFilter and PATH problem in 5.4.1

[Martin Weinberg]

An easy fix is adding:

export PYTHONUSERBASE=/dev/null

to my bash script that sets the LD_LIBRARY_PATH and PYTHONPATH and
"wraps" the paraview invocation.   I also tried setting PYTHONNOUSERSITE
but that did not help.

Thanks, Shawn for the discussion and may this help someone else down the
line.

Re: [Paraview] Help with ProgrammableFilter and PATH problem in 5.4.1

[Martin Weinberg]

Okay . . . I figured out the problem but not the fix.

The problem is: I installed some packages with pip, and python is
prepending ~/.local/lib/python2.7/site-packages paths to PYTHONPATH even
when I rewrite the that path in the shell.

So if I temporarily rename ~/.local/lib/python2.7/site-packages to
something else, the programmable filter works as expected.

Any idea how to best handle this?

Re: [Paraview] Help with ProgrammableFilter and PATH problem in 5.4.1

[Shawn Waldon]

Hi Martin,

My first guess would be that your state file is trying to load data that
isn't there.  Then when you run your programmable filter inputs[0] is None
and you get this error message.  I can't think of anything else that could
be going wrong with that script, especially since it works on one of your
machines.

HTH,
Shawn

[Paraview] Help with ProgrammableFilter and PATH problem in 5.4.1

[Martin Weinberg]

I have two nearly identical machine running Ubuntu 17.10.  The both have
the latest stable Paraview 5.4.1 from the download page installed in /opt.

I wrote a wrapper script like this:



#!/bin/bash

# PVHOME=/opt/ParaView-5.4.1-822-g597adef-Qt5-MPI-Linux-64bit
PVHOME=/opt/ParaView-5.4.1-Qt5-OpenGL2-MPI-Linux-64bit

export PATH=$PVHOME/bin
export LD_LIBRARY_PATH=$PVHOME/lib/
export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:$PVHOME/lib/paraview-5.4/
export PYTHONPATH=$PVHOME/lib/python2.7/bin/
export PYTHONPATH=$PYTHONPATH:$PVHOME/lib/python2.7/site-packages/
export PYTHONPATH=$PYTHONPATH:$PVHOME/lib/python2.7/site-packages/vtk/
export PYTHONPATH=$PYTHONPATH:$PVHOME/lib/python2.7/site-packages/paraview/

$PVHOME/bin/paraview


On each machine I start paraview and load a state that has a
programmable filter with the line:

d0 = inputs[0].PointSet['d']

One one machine, this works just fine.  On the other machine, I get the
following message in the Output:



Traceback (most recent call last): File "", line 24, in File "", line 2,
in RequestData TypeError: 'NoneType' object has no attribute '__getitem__'

BTW, this is just a test; obviously, my real filter does something.

I assume that some module is not being loaded here, but I've tried
_everything_ I could think of and I'm not making progress.  Any ideas??

Re: [Paraview] Help

[Moreland, Kenneth]

Mohammed,

The answer to your question depends on a lot of things.

Depending on your simulation, it might be easiest if the simulation itself 
detected when a particle exits the pipe. It is, after all, the thing tracking 
the particles to begin with. From there it could output its count in a csv 
file. You could load that up and plot in in ParaView, although a typical 
spreadsheet program can do that as well.

Assuming it is not feasible to have your simulation do the count, getting 
ParaView to do it depends on a lot of things. First, it depends on whether 
particles “die” in your simulation. It is pretty common in simulation code to 
have particles leave the defined domain (or otherwise become invalid) and then 
get removed from the list of particles that get written out. If particles never 
die, then your job in ParaView is easier. You can just count how many particles 
are past the out end of the pipe and count that.

If particles are born or die in your simulation, then the problem becomes much 
more difficult.
