A 3d induction heating example

A 3d induction heating example

The main limitiations with this analysis type are 1) you can't have a
B-H curve in a harmonic analysis and 2)  BH curves are not temperature
dependent.  Given these limitations, the most accurate thing that can be
done is to define a series of effective constant permeabilities, and
assign elements different material set numbers based on their H value.  
Of course, this would be an iterative process.
