Finite Element Method Magnetics
A Windows finite element solver for 2D and axisymmetric magnetic, electrostatic, heat flow, and current flow problems with graphical pre- and post-processors.
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
There is a new build New Build
page. The New Build version may contain additional features and bug fixes but has not yet been extensively tested.
Old versions of FEMM, Bela, and Mirage are also still available on the OldVersions
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
Recommended distributions of Gnu Octave that run on Windows are:
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:
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).
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.
