<div class="moz-text-html" lang="x-unicode"> Hi,<br>
<br>
I am using paraview to visualise my data. I generate my data using
a combination of the 2 following types (<a

<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-indent: -53px; text-transform: none; white-space: pre-wrap; word-spacing: 0px; background-color: rgb(251, 252, 253); display: inline ! important; float: none;">VTK_POLYHEDRON = 42
</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-indent: -53px; text-transform: none; white-space: pre-wrap; word-spacing: 0px; background-color: rgb(251, 252, 253); display: inline ! important; float: none;">VTK_POLYHEDRON </span></font>in
order to investigate the problem.<br>
<br>
I found out that only the polyhedrons with the largest size were
having the problem. The limit is somewhere between the 2 files:<br>
- poly-F1000-2395.vtu : working: 466 points, 928 faces <br>
- poly-F1000-2987.vtu : segfault when slicing: 546 points, 1088
faces <br>
<br>
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>
<br>
My questions are : <br>
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>
2) If there is this limitation, is there an option to remove it in
Paraview ? (specific version, compilation option, etc) <br>
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>
<br>
<br>
I attached the data to be able to back up my statement:<br>
<br>
poly-F1000-*.vtu : files describing a polyhedron each: <br>
poly-F1000.pvd : load all those files<br>
<br>
Biggest file for which the slicing works (size, name):<br>
34K poly-F1000-2395.vtu<br>
<br>
The 8 biggest files triggering the crash when doing a slice:
(size, name)<br>
38K poly-F1000-2987.vtu<br>
39K poly-F1000-2983.vtu<br>
39K poly-F1000-2935.vtu<br>
39K poly-F1000-2988.vtu<br>
39K poly-F1000-2931.vtu<br>
40K poly-F1000-2937.vtu<br>
40K poly-F1000-2981.vtu<br>
40K poly-F1000-2930.vtu<br>
fail.pvd: load those 8 files<br>
<br>
the other files can be sliced without any issues<br>
<br>
<br>
Thanks, <br>
