Hi @GLuek , this seems like amazing work!
I’m also interested in automatically generating simulations, but starting from a GDS layout + descriptions of the layers. We can already generate relatively complex CADs that I then mesh using GMSH constructive geometry. See a relatively simple 2D example here: Troubleshooting a faulty mesh? (we have done much crazier stuff for our FEM solvers)
How mature is your toolchain? I’m wondering it I can apply it, because my geometry parser can already generate 3D models. If I initially have physicals tagged (3D volumes and 2D interfaces/contacts), can we apply your fix to the mesh, and easily retag the physicals?
