Do you want a faster mesher or a faster fea solver?
Do you want a faster mesher or a faster fea solver?
(OP)
If you had to pick one, would you pick a faster mesher (faster cad defeauturing, midsurface extraction, volume and surface mesher, etc) or would you pick a faster solver (Ansys, Abaqus, MSC Nastran, etc)?

There is an awful lot of manual midplaning and editing with a fabrictaed assembly of hundred and hundreds of parts plus one needs to judge how these parts are connected to determine relatsic load transfer and stiffness. the FEA systems in the CAD programs are very primitive and despite vendors claiming they can help us they have not convinced us except for quick and dirty analysis of single casting part.

but i agree with FEA in CAD programs ... it's best avoided, it's very limited, very "canned", quite open to making pretty pictures.

I thought every mesh had to be "drawn" across the (outside) surface approximating all of the solid part, then developed through the cross section of each region of the part so all of the physical geometry is "filled" and every analysis cube touches its neighbor so the diff. equations "match" at every touching surface; and the mesh has to be cubic/near-cubic in shape everywhere - not a mix of triangles and cubes, with different number of cubes in different regions.

no, that is not a sign of a good mesh, in fact a durability engineer will often refine the mesh at hot spots while leaving the bulk of the mesh undisturbed.
