• FEMM 4.2 Executable (02Nov2009)
• FEMM 4.2 Source (Builds with MSVC++ 6.0 or later)

The FEMM 4.2 distribution includes toolboxes for interacting with FEMM from Octave/Matlab and Mathematica. Recommended distributions of Gnu Octave that run on Windows are:

• QtOctave 0.7.2 Distribution. Gnu Octave 3.0.0 with a nice front end.
• Gnu Octave 3.2.0 Distribution. (Make sure that Octave-Forge is selected for installation)
• Gnu Octave 3.0.3 Distribution. (You may also need the VC++ 2008 Redistributable Package)

These distributions are recommended because they come with the Octave-Forge "Windows" package. This package speeds up the communication between Octave and FEMM.

Old versions of FEMM are also still available. FEMM is licensed under the terms of the Aladdin Free Public License. The Triangle mesh generator and the Lua scripting language, which are included in the distribution, each have their own licensing terms. These programs come 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.
