Hello,
I am trying to model a magnetic core in high frequency in flux, and when defining the material, I found the linera isotropic complex magnetic property.

There, I introduce the real and complex permeability curves, that depend on frequency, with of the lamination of material and resistivity.
In the resistivity of the material, I introduce the same resistivity value.
However, when defining the face region, I don´t know if I should declare it as a solid conductor, or declare it as a magnetic non-conducting region.
Does someone have any idea of what it the correct way of doing it?
Thank you in advance
Yerai
