Pointwise Mesh Generation to COMSOL

lbarkett · November 12, 2013, 20:08

Has anyone ever tried to create a 3D mesh in Pointwise and import it into COMSOL? Sometimes COMSOL complains about importing geometry, so I was wondering if mesh importation was any different. Is it painless or full of pain?

Laura:

We have successfully transferred meshes from Pointwise to Comsol by exporting them as NASTRAN bulk data files. One gotcha currently is that Pointwise exports pyramids as collapsed prisms while Comsol expects them as CPYRAM elements. We are working on an option in Pointwise to export pyramids either way: as collapsed prisms or a CPYRAMs.

All the other element types import just fine.

Hope this helps,
Rick
