<small>Hi,<br>
<br>
First of all, this concerns ParaFOAM edition and I am not sure if
this is the right place to seek support. I am trying to use saved
python state and code samples from paraview wiki to create a
script that would read results, create two filters, set display
properties and generate animation. The script works fine with
"DataRepresentation1.Opacity" set to "1" (line 110 - the script
attached below), but throws segmentation fault when I decrease it.
Unfortunately, I need it at 0.1 to show the outline of the
container during filling, so this is a serious problem. I do not
get this error, regardless of opacity setting, when no images are
saved (i.e. last line: "AnimateReader(results_OpenFOAM)").<br>
<br>
This error should be easy to reproduce using the results of the
"Dam Break" OpenFOAM tutorial. I did this by entering the tutorial
directory, creating script.py and starting the post-processing
with command "paraFoam --script=script.py" (with opacity set to
less than 1).<br>
<br>
As I am a beginner, any help would be appreciated.<br>
<br>
Best regards,<br>
Yarek<br>
<br>
P.S. I have one question regarding the scripting itself: could
someone explain to me how to set the image resolution and number
of frames per time step for an animation which is defined like it
is defined in my script?<br>
<br>
<br>
