Electromagnetic Fields with PERMAS
PERMAS-EMS - Electro- and Magnetostatics
This module allows for steady-state electromagnetic analysis. Magnetic analyses may be based on a previously performed calculation of the steady-state current distribution. The analysis uses a scalar potential for the electric field and a vector potential for the magnetic field.
Various load types are supported.
The determination and handling of singularities is analoguous to a static analysis.
Heat induced by an electrical field can be used for a subsequent thermal analysis.
From that thermal stresses can be derived performing a subsequent static analysis.
Forces induced by a magnetic field can be used in a subsequent static analysis.
PERMAS-EMD - Electrodynamics
A solution of Maxwell's equations is available for different problem cases:
- eddy currents
- induction problems
- resonant cavities
- wave propagation
- general electrodynamics
All kinds of loading may be applied in dynamics (like prescribed potential). The specification is made by static loading cases and appropriate time functions like in structural dynamics.
