Generic Error

Hello everyone,

I am using the COMSOL 4.4 AC/DC Module to reach the saturation of an electrical steel block with the help of (two) current coils. Therefore I implemented a HB-curve in the materials data for the steel block and created two coils (type: "numeric") with a certain amount of current.
When I start to "compute" my simulation I immediately recieve a error message and the calculation stops:

"Interner Fehler im Auxiliary space Maxwell Löser.
- Detail: Generic error."

Does anybody have experience with this error massage or know the reasons why it appears?

Thank you very much.

Regards,
Richard
