I get the error shown in the title of that post with my simulation. I'm trying to simulate an electromagnet in 3D with Comsol 4.0. I succeeded in 2D, but I need it in 3D for future work.

I succeeded to simulate the magnet alone, but when I use that model and close the magnetic path with iron around it, Comsol never converge.

I tried refining and enlarging the mesh, but without success. I wondered if you would have any idea.

Thank you very much,
