Hi Kpamsar,

I am also new in COMSOL and I think this message is because of your 3D model. As far as I know you can import 2D slice in DXF format. Although there may be a way to import a 3D model in a series of 2D slices, I am not familiar with that and I am looking for it right now. Try with one 2D slice and see what happens.

Good luck,
saeid
