Hello

I have a problem with my model. I'm trying to simulate an disk-rotor linear induction motor in 3D (Imported from autocad), seeing as devising a 2D model is out of the question. Instead of Soft Iron without losses, I chose a different material (somaloy), modeling it based on said soft iron, changing the b/h curves.

In stationary, using the magnetic fields physics, everything works more or less okay and I obtain the values of the B-field easily. However, when I try simulating it in the frequency domain, using the same physics package, it never seems to converge.

I then thought it might have something to do with the fact that I would have moving parts (rotor) so I opted for the Rotating machinery package. Seeing as the coils do not have a circular or linear shape, I chose them as numeric. This means that I'd have to use a cylinder (surface) to define the way the currents trasverse the coil. However,whenever I choose form assembly (to define continuities and id-pairs), it's not possible for me to choose the cylinder surface as an indicator for the current orientation.

Does anybody know how I can solve this issue?

Thank you,
Papo
