<br class="">
I am using paraview to visualise my data. I generate my data using
a combination of the 2 following types (<a class="m_-1893844449759964379moz-txt-link-freetext" href="http://www.vtk.org/doc/nightly/html/vtkCellType_8h_source.html" target="_blank"></a><a class="m_-1893844449759964379moz-txt-link-freetext" href="http://www.vtk.org/doc/nightly/html/vtkCellType_8h_source.html" target="_blank">http://www.vtk.org/doc/<wbr class="">nightly/html/vtkCellType_8h_<wbr class="">source.html</a>)<br class="">

</span>I can visualize that data with parview without a problem. But,
because I ended up having a segfault without any error message
when slicing (Z=0) the data. I decomposed my data in separate
files for each <span style="font-family:monospace,fixed;font-size:13px;font-style:normal;font-variant-ligatures:normal;font-variant-caps:normal;font-weight:normal;letter-spacing:normal;text-align:start;text-transform:none;white-space:pre-wrap;word-spacing:0px;background-color:rgb(251,252,253);display:inline!important;float:none" class="">VTK_POLYHEDRON </span></font>in
order to investigate the problem.<br class="">
<br class="">
I found out that only the polyhedrons with the largest size were
having the problem. The limit is somewhere between the 2 files:<br class="">
- poly-F1000-2395.vtu : working: 466 points, 928 faces <br class="">
- poly-F1000-2987.vtu : segfault when slicing: 546 points, 1088
faces <br class="">
<br class="">
So my guess is that there is a limit for the number of points or
the number of faces that can have the polyhedron (1024 ?) if I
want to be able to use the slice function.<br class="">
<br class="">
My questions are : <br class="">
1) Is there actually a limitation in Paraview (VTK?) regarding the
number of faces or the number of the point that the slice function
can handle for a polyhedron ?<br class="">
2) If there is this limitation, is there an option to remove it in
Paraview ? (specific version, compilation option, etc) <br class="">
3) If there is this limitation, is there any work around that
exist so I am able to slice my data ? For example a different
format ?<br class="">
<br class="">
<br class="">
I attached the data to be able to back up my statement:<br class="">
<br class="">
poly-F1000-*.vtu : files describing a polyhedron each: <br class="">
poly-F1000.pvd : load all those files<br class="">
<br class="">
Biggest file for which the slicing works (size, name):<br class="">
34K poly-F1000-2395.vtu<br class="">
<br class="">
The 8 biggest files triggering the crash when doing a slice:
(size, name)<br class="">
38K poly-F1000-2987.vtu<br class="">
39K poly-F1000-2983.vtu<br class="">
39K poly-F1000-2935.vtu<br class="">
39K poly-F1000-2988.vtu<br class="">
39K poly-F1000-2931.vtu<br class="">
40K poly-F1000-2937.vtu<br class="">
40K poly-F1000-2981.vtu<br class="">
40K poly-F1000-2930.vtu<br class="">
fail.pvd: load those 8 files<br class="">
<br class="">
the other files can be sliced without any issues<br class="">
<br class="">
<br class="">
