Multiple materials and Mesh

Hi FEM users, i try a simple example with two cylinders (see attachment freecad_cylinder screenshot) center cylinder is in copper with potential of 1V and external cylinder is in glass. The external surface is at the potential of 0V. Inspired by https://github.com/FreeCAD/FreeCAD/tree/master/src/Mod...

Re: Gmsh Error

What is really important, what are your FreeCAD infos? See 2nd link in the red banner, point 4. Without that, it is pure guessing into the blue. This is also the reason, why nobody (can) gives an answer. Ok i notice this. I continue my fem test with freecad and elmer. thanks for all reader. regards
