The program comes with no warranty or support. However, there is an independent FEMM user's group at http://tech.groups.yahoo.com/group/femm/ and many frequently asked questions are addressed in the FAQ.

Old Versions

The FEMM 4.2 distribution includes toolboxes for interacting with FEMM from Octave/Matlab, Scilab, and Mathematica.

Octave/Matlab

Recommended distributions of Gnu Octave that run on Windows are:

• Gnu Octave 3.6.2 Distribution.
• Gnu Octave 3.6.1 Distribution.
• Gnu Octave 3.2.0 Distribution.
• Gnu Octave 3.0.3 Distribution.
• QtOctave 0.7.2 Distribution.

FEMM needs the Octave-Forge "Windows" package to efficiently communicate with Octave. In recent versions of Octave, Octave-Forge must manually be select during install:



After installation, you'll need to add FEMM's mfiles directory to Octave's search path:



For Matlab, add the mfiles directory with the interactive pathtool command.

Scilab

Scilab can be obtained from http://www.scilab.org/. The SciFEMM interface is automatically included in every installation. 64-bit FEMM requires 64-bit Scilab for the the two programs to successfully communicate (and 32-bit FEMM requires 32-bit Scilab).

Mathematica

The MathFEMM interface to Mathematica has been tested on Mathematica 4.2, 7, and 9, though it may work on other versions. The package works with either the 32 or 64 bit versions of Mathematica. Mathematica must be installed prior to FEMM installation. Otherwise, FEMM will not prompt for the installation of Mathematica support during installation.
