I have a CFD dataset consisting of hex and polyhedral cells. When I try to apply vtkCutter using a plane on the dataset, VTK crashes for some polyhedral cells.
I then found that it was crashing when I tried to cut through a polyhedron which has more than 512 vertices.
I found a similar issue reported on Paraview : https://www.paraview.org/pipermail/paraview/2017-January/038874.html
I have a simple script which generates a polyhedron as shown below
In the script, I increase the number of the quadrilateral faces on the visible side in the image to increase the total number of vertices of the polyhedron.
I apply a vtkCutter on the polyhedron and my python VTK script crashes only when I have more than 512 vertices.
I am attaching a polyhedron cell with 514 vertices .
This polyhedron can be loaded in Paraview 5.4 and applying a slice filter on it crashes Paraview as well.
I am creating a simple polyhedron cell with all planar faces and bounds of the polyhedron are big enough (0,254,0,5,0,5)polyhedron_514verts.vtu (19.6 KB)
