To model FEM heater efficiency we could add an FEM plugin to gdsfactory

what do you think?

For both FEM and semiconductor TCAD, the first step would be to have suitable meshing of the components (3D), or components cross-sections (2D)

I know we already have Trimesh for visualization, but having the option for adaptive meshing would be very helpful. Gmsh (has a Python interface, and used in the Freecad pipeline linked above) does this, see http://web4.cs.ucl.ac.uk/research/vis/toast/demo_meshgen3/demo_meshgen3.html

Another thing is that once we have a mesh in one format we can easily convert to any other format with meshio

Then any finite element solver would be good. Examples:

• DEVSIM (can implement arbitrary models, not just semiconductor)
• Freecad (above)
• MOOSE
• FeNics
  etc.
