Dear Vadims, 

The inductor case does not work if you combine nonlinearity and frequency domain. 
The nonlinear bh-curve should be adapted, you need an effective nonlinear magnetic curve. 

This can be done by applying an effective energy or average effective energy method. 
Have a look, e.g. at:
Gerhard Paoli, Oszkár Biró, and Gerhard Buchgraber. “Complex representation in nonlinear time harmonic eddy current problems,” Magnetics, IEEE Transactions, vol. 34.5, pp. 2625-2628, 1998.

This feature is not yet available in GetDP. It is still in our TODO list. 

Best regards,
