H-B curve in comsol

Dear colleagues,
I'm currently learning COMSOL, and my first model is a Terfenol model in COMSOL 5.5, for this purpose I'm using the Solid Mechanics (solid) module and the Magnetic Fileds (mf) module. To take into account the H-B curve of Terfenol, in mf I'm using the "Amper's law" node with "constitutive Relation B-H" as "B-H curve", but since Terfenol is a nonlinear magnetostrictive material I want to take into account its H-B curve instead of B-H curve.
I looked up in the COMSOL gallery and I found that is possible to use the H-B curve, but I cannot find how to activate this option in the mf module.
I also found that by using "Soft Iron (without losses)" I can obtain the nonlinear H-B curve, but when I'm using this material the "constitutive Relation B-H" in the "Amper's law" node is kept as "B-H curve".
Can you please give me some advice on how to resolve this issue?
Best regards.
