FEMM

The Finite Element Method Magnetics (FEMM) project aims to provide you with easy to use tools for solving electromagnetic problems with minimum effort. It includes a set of programs that allows you to specify the problem parameters, analyze them and provide a viable solution.

The Finite Element Method is a mathematical approach to solving various problems by using several equations to approximate a complex equation that provides a stable solution. This program allows you to implement the method for magnetics and electrostatics.

In order to solve your problem you need to specify the parameters in a CAD-like application and use one of the available solvers to find the solution. FEMM is the name of the main tool from the package which allows you to create the problem design and access the solvers.

Its interface is easy to use and allows you to add objects, symbols and materials to define your problem. You can also import the layout from DXF or extended metadata files. The application supports Lua scripting which allows you to automate certain actions and process multiple problems with minimal user interaction.

After the problem has been configured you can call one of the solvers from the Analysis menu which also displays the results after the solving is finished. You also have the option to generate a plot of integrate the solution.

If you are using the program for the first time, you should read the included manual before creating problems or starting to analyze them. The package also includes samples that can help you understand and test the main features.

The FEMM tool pack can help researchers and students save time when they need to solve low frequency electromagnetic problems.
