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

Please login with a confirmed email address before reporting spam

Hi,

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

Hello,

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,

Catalin B.
