magnetostatic analysis software, dc magnetics analysis, direct current magnetostatics simulation, dc magnetic modelling package

The DC magnetic (magnetostatic) module may be used for analysis of problems, which require calculation of static magnetic fields caused by combination of local and/or distributed direct currents, permanent magnets and also external fields defined by boundary conditions. DC magnetics is similar to AC magnetics in the where the current frequency is low enough for the problem to be considered static. But unlike AC Magnetic, DC Magnetic module allows inclusion into the field model any number of non-linear magnetic materials and permanent magnets with known coercive force.
The DC magnetic module is used for design and analysis of devices such as solenoids, electric motors, magnetic shields, permanent magnets, disk drives, and so forth.
