Anisotropic BH

Hi guys,
I have a material with anisotropic BH and am trying to apply this property to Comsol. Does anyone know how this can be done?
With a linear BH relationship, I have been able to do this by applying anisotropic permeability in the Magnetic Fields/Ampere's Law section under Constitutive Relation: Relative Permeability, User Defined, Anisotropic. However, with the non-linear BH relationship, this permeability is no longer constant.
Does anyone have an idea of how this can be done?
Many Thanks,
Laura

Hi,
the question how your anisotropic BH-model looks like. Do you have functions like
Hx=f1(B,x,By,Bz)
Hy=f2(B,x,By,Bz)
Hy=f3(B,x,By,Bz)?
One way of solving your problem is going to the equation view
and override the default definition of the magnetic field with these
function. Not easy to get everything right and to converge but possible.
