I guess to split off the Future of FEM to a separate topic??
I think it's an interesting topic too!

all gmsh is done in Python whereas all Netgen needs to be done in C++. My knowledge of Python is just much better than my knowledge of Netgen (at the time of writing gmsh object the knowledge difference was even bigger than it is nowadays).

Python 3 should also close to the top...
but that one have its own topic :P
These are related. Newer Netgen has Python bindings, but requires PY3. @bernd these Netgen Python bindings are available in the Conda based Win builds.

Has any progress been made to support Hex meshes in FreeCAD for FEM
It seemed possible from this tread ?
https://forum.freecadweb.org/viewtopic. ... 40#p215380

Good Hex mesh for would Increase usability of FreeCAD with complex geometries I run into bad elements often with Tet meshes

My 10cents worth

AFAIK, hextreme is joined now into gmsh master (experimental for testing)

https://www.hextreme.eu/

Here is a short reply from Christophe Geuzaine about usage

But to be honest, I just can't get to work :oops:
