I have a domain that I’m exporting from CFD results (exporter written by me). This domain has mixed cell types, mostly polyhedra & hexahedra.
When I clip the domain, without crinkle cut, I receive the following warning
Generic Warning: In vtkPolyhedron.cxx, line 1801
A cell with a non-manifold triangulation has been encountered. This cell cannot be contoured.
When I crinkle-clip the clip, the error is gone.
Can someone:
a) what is causing the different behaviour when clipping with crinkle vs without
b) explain how I can find the troublesome edges to check if it’s my export process causing this.
I’m not sure if the following is related, but when opening my files in paraview 5.11 the hexahedra cells look “broken” without crinkle clip.
Without crinkle:
With crinkle:
5.13 does not exhibit this issue, but I’m wondering if this is related to the non-manifold issue.
