RE: [femm] Re: Skin effect at nonsinusiodal current

Just one correction: you can use the below mentioned superposition
method only in case of linear system. In case of nonlinear effect such
as ferromagnetic material near the "wires and cables" the accuracy of
the calculation will not be sufficient.

A common approximation is to compute SE and PE for each (significant)
frequency component of the input waveform then add the power loss for
each component.
