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**?
Mick

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
