Timm,
There is a product that I know of called Flux2D and Flux3D, which
are magnetic field and structure FEA packages.
I have actually used a program called ATILA, made by the same
company, which is a powerful piezoelectric analysis package,
much better than ANSYS in that respect.
To find out more you can look at the supplier/writers web page:
http://www.cedrat-grenoble.fr or email them on cedrat@cedrat-
grenoble.fr

I hope this helps
