[FEMM] BH curves, intrinsic?

["Jean-Michel Le Cléac'h" <jean-michel.le_cleach@xxxxxxxx>]

Hello,

I want to enter a new ferromagnetic metal in my "material library".

I have the intrinsic BH curve of the metal.

After editing all the BH curves for ferromagnetic metals in the actual FEMM
library, I can see that the BH curves are not the "intrinsic curves" but
that a term in ( 10^6 . H ) is added (probably to enter the "total" B at a
given H).

This is specially important for high H values because if I enter the
intrinsic curve, saturation can occur. When using as the B value the
(intrinsic B + 10^6 . H ) value, the curve has an asymptot.

Is there any document dealing with the way a BH curve has to be entered in
the library.

Any help will be appreciated.
