This is a repost from "Maxwell 3D question", anyone know how to do
this?.....

Thanks for the reply. Actually I have a decent understanding of diff.
equations and Maxwell's. My question was a software question for
Ansoft's "Mawell 3D" FEA software. I have a coil that I modeled as a
large toroid (with square CS). The J density function is, for my case,
using cartesian coordinates:
Jx=Jmag*(z/sqrt(x*x+z*z))
Jx=Jmag*(x/sqrt(x*x+z*z))
Jy=0
The problem I'm having is defining the above equations in the
Boundary/
Source Manager under Model -> Function. The functions I'm trying to
define "Maxwell 3D" calls "Functions of Position" in there help files.
I can't find any examples on the web.
Maybe someone knows how to do this, or better yet has a Maxwell 3D
project on hand that I can learn from.

Thanks
