3D magnetic+mechanic

I need to study a problem with a coil moving inside a magnetic field. Giving V0 my 3D study works well in stationary, but when I load the coil with linper(V0) for the Frequency-Domain, Perturbation an error occurs with "NaN or Inf found when solving linear system using SOR".

I compared the settings of my model with the built-in loudspeaker driver, my application is different, without acoustic, but magnetic+mechanic behaviour is similar.

Could anyone help me figure out what may cause the error?

Hello.

Have you managed to solve your problem? I have a similiar one and it's proving to be quite a difficult task to get it working.
