FEMM

FEMM: Free Finite Element Analysis Software

FEMM is free finite element analysis software for low frequency electromagnetic simulations. It allows you to solve static, frequency domain, and time dependent problems in electromagnetics and magnetostatics.

What is FEMM?

FEMM is free, open source software for solving low frequency electromagnetic problems on two-dimensional planar and axisymmetric domains. It allows you to model static magnetic fields, steady-state magnetic fields and induced currents, frequency domain problems such as eddy current effects, and time-varying magnetic fields. Some key features of FEMM include:

• Intuitive graphical user interface for drawing geometry and assigning materials/excitations.
• Fast, high precision solvers for magnetics and electromagnetics problems.
• Support for user-defined nonlinear magnetic materials.
• Optimization tools for design problems.
• Integrated post-processing for flux lines, contour plots, etc.
• Python scripting interface.
• Cross platform - works on Windows, Mac, and Linux.

FEMM is useful for analyzing devices/systems such as transformers, actuators, sensors, and rotating machinery. It can account for effects such as hysteresis, eddy currents, and strand coupling losses. The software is actively developed by David Meeker and has an active user community supporting it.
