Three-dimensional magnetostatics with high-permeability materials and permanent magnets.

Description | More information | Demos | Pricing | Sectors | Platforms

Magnum is a complete tool for 3D finite-element magnetostatic calculations. The program achieves unprecendented accuracy and speed at a moderate price. Magnum can perform three types of calculations: 1) free-space fields in unbounded volumes for given applied currents, 2) bounded fields in the presence of coils, permanent magents and linear-isotropic ferromagnetic materials and 3) pulsed fields in regions with ideal conductors. The package includes two additional programs: CPrep (a preprocessor for definition of drive coils) and MagView (a postprocessor for 2D/3D plots and analyses). Magnum has extensive applications to the design of magnets (with and without iron) and permanent magnet assemblies. (Available for Windows and Linux. MetaMesh required.)
