The program comes with no warranty or support. However, there is an independent FEMM user's group at and many frequently asked questions are addressed in the FAQ.

Development Builds

Any available development builds or "works in progress" will appear on the NewBuild page.

Old Versions

Old versions of FEMM, Bela, and Mirage are also still available on the OldVersions page.


FEMM uses Triangle 1.3 for mesh generation, but alternate versions of Triangle are avalable on the Triangle page.

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


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


Recommended distributions of Gnu Octave that run on Windows are:

FEMM needs the Octave-Forge "Windows" package to efficiently communicate with Octave. In 3.6.X versions of Octave, Octave-Forge must manually be select during install:

Select OctaveForge during the install of Octave

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

Add FEMM mfiles directory to Octave search path


Scilab can be obtained from 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).


The MathFEMM interface to Mathematica has been tested on Mathematica 7, 9, and 10 though it may work on other versions. The package works with either the 32 or 64 bit versions of Mathematica.
