Analytical modeling options

(OP)
Folks,

I'm just looking for a few opinions (as I believe endorsements are not appropriate here)for some modeling software.  My problem is designing an A.C. inductive coil sensor that gets loaded by nearby metals.  I'd like to model the complex impedance response and determine magnetic shielding for the coil sensor.  I'm interested in both ferromagnetic materials and conductive materials.  Options under consideration are closed form packages that require the governing differential equations, and FEA based packages.  Software prices are all over the map from what I can tell.  I think most of my needs can be met with an axisymetric 2-D package.  What do you all think?

RE: Analytical modeling options

if all you need is axisymmetric 2-d package, FEMM is pretty good. It's free and has a good user forum on yahoo groups.  Has a good interface with Matlab.

This probably would get more responses in the magnetic forum.

Thank you.  Also, when you mean "more responses in the magnetic forum"  the one we are in now was the only one I found on this site.  Are you referring to another site, perhaps Yahoo?

RE: Analytical modeling options

No, I had several tabs open at the same time... forgot what forum I was in.  spineyes
