Split complex variable in real and imaginary parts and iterative solver configuration

i'm tring to simulate an indutcor that produce some joule heating on a thin slab. This slab is a non linear material and has a HB curve. I work with 30kHz and i'm using a frequency solver with an iterative solver (GMRES). In order to increase the stability of the solver i activate the "split complex variable in real and imaginary parts" in the compile equation submenu. when i run my simulation i get the following error:
Undefined value found.
- Detail: NaN or Inf found when solving linear system using SOR.
I'm using a multigrid preconditioner.
Can someone help me.
Cheers
Nicola

I am experiencing a similar problem: I am trying to do an analysis in frequency domain, for a SAW.
The physics is piezoelectric devices.
The error message I get is:
"Undefined value found.
- Detail: NaN or Inf found when solving linear system using SOR."
Anyone knows where the problem might come from and which is the solution?
Best regards,
