Dear sir/mam,
currently I am working with AC/DC module of comsol 4.3a. I have to solve the model for my nonlinear BH data. In solver >> stationary solver>>linearity we have an option to change nonlinearity. But it did not change the result. what we have to do to solve the model for nonlinaer BH curve.

Hi

You need to define a new Linear material for the non linear Iron, then use your BH curve for the B to H link (or the H to B depends how you have set up your model, check the doc)

There should be a good model library example in there somewhere ;)

Good luck
