Polyhedral meshes specific visualization

ParaView Support
1

Hi all,

I am wondering if it is possible to display “volume” of cells of a polyhedral mesh in ParaView.

Moreover, is there a filter to compute the cell squish index of a polyhedral cell. (is it hidden in the mesh quality filter that uses verdict library ?)

Least but not last, is there a way to color a polyhedral cell faces by their areas ?

Yes

Sounds like this require a specific computation, in a python filter.

ExtractSurface + CellSize ?

I am not sure you understood well the volume question.
What I want to display is the quantity volume of a polygonal cell not do a volumic rendering. Thus how do I compute the volume of a polygonal cell in ParaView ?

I am not sure that a python filter is efficient enough to compute dot product on triangulated faces

Indeed, I misunderstood.

CellSize should compute it.

Why not ?

Thanks for the reply anyway
