CST EM STUDIO® (CST EMS) offers customers to select from an electrostatics, a magnetostatics, a stationary current flow,
and low frequency frequency and time domain solvers. CST EMS solvers can be included in a multi-physics design flow via CST MPHYSICS STUDIO® (CST MPS). Results can be transferred from one solver to another in order to simulate coupled problems.

The Electrostatics Field Solver is useful for a wide range of static or quasistatic applications like high voltage devices, or capacitors of any kind.

The Magnetostatics Field Solver is a very fast alternative to the low frequency solver.
It is mostly used when eddy currents are not important or when materials have a non linear characteristic. Additionally an automated impedance calculation is available.

The Stationary Current Field Solver is mainly used to compute current distributions in lossy materials. In a second step these field distributions can be used for a magnetostatics computation.

The low frequency domain Solver can be best applied to problems with non negligible losses. Eddy currents, loss densities and energy densities can be calculated in addition to electric and magnetic fields. Moreover it contains an option to consider wave propagation in a device (this means that the displacement current is considered)

The strength of the low frequency time domain solver is the inclusion of non linear effects in low freqeuncy simulations.
