Model BH-curves with remanent flux density at H=0

Hello,
I make some studies to determine the magnetic properties of metals and have to take in account a small remanent magntic flux density B.
I defined a sample material with a known BH-curve and at H=0 I set a small value for B.
But I always get the error no solution found even with minimum step size.

Is there a other possibilits to simulate nonlinear materials with a small remanent flux density.

Thanks for your advices.
