Brad:
You are definitely right to contact an ansoft AE. However, it could also be
nice to have another source of data.
Hope people doing similar stuff can share their material library.

Neo

hi Neo,
your best bet is to contact your local Ansys apps engineer
Of course, Q3D is a DC RLC extractor so not certain how much frequency
dependent material properties is going to buy you :-)
Any Q3D "extraction frequency" is to define the skin loss approximation
applied for so-called AC results that are actually provided from a
magnetostatic (i.e. DC) solver which uses surface currents.
