MathFEMM
MathFEMM is a Mathematica package for commanding and exchanging data with FEMM from inside a Mathematica notebook. The commands mirror the functionality of FEMM's Lua scripting language interface.
Here is an example PDF print-out of a Mathematica notebook using MathFEMM.
As of FEMM 4.2, the MathFEMM (and OctaveFEMM) are included in the standard FEMM distribution. The MathFEMM package is located at
C:\PROGRA~1\femm42\mathfemm\mathfemm.m in the standard installation.
