Is there a way in fasthenry to specifiy the permeability used in the calculations? Also can one set a different mu for different objects? For example can inductance be modeled when ferromagnetic materials are near by?
Current version of FastHenry2 does not manage permeability of material. You can specify sigma, the conductivity, or rho, the resistivity of a conductor, to model skin/proximity effects, but you cannot at present model ferromagnetic materials.
