Problem with imported BH curve

Hello everybody,
I'm pretty new to Comsol, but I think I already understand at least the basics ;)
I've got a working simulation file of a magnetic coil. The used material is not from the included library but modified using an external BH curve of the iron. Now I tried to modifie the material using other BH curves I found on the Internet. I didn't change anything on the geometry, I only deleted the old BH data and imported the new data. I got the new BH curves from www.femm.info/wiki/softmagneticmaterials.
Now I always get errors like:
"No solution found.
Divergence of linear iterations.
Solution does not converge." (Translated)
or
"No soluton found.
Maximum number of Newton-iterations reached.
Solution does not converge." (Translated)
Does anyone of you have an idea what could help solving my problem?
I'd appreciate any hint.
Greetings
JO

Hi,
If you have imported new data, you might want to revisit the boundary conditions. That might be causing the non-convergence.
