Hi,

you can apply a magnetic potential to the boundaries of the model. In case of mfnc this would be the scalar potential Vm = 1[A/m]z for a field of 1 A/m in z-direction. In case of mf it is Ar = 0, Aphi = 0.5[T]r and Az = 0 for a field of 1 T in z-direction.

Of course any magnetization inside the model will distort this field.

Cheers Edgar
