Overview of Multiphysics Couplings
The AC/DC Module contains a number of Multiphysics Coupling features that can couple electromagnetic domains to heat-transfer media, structures, and charged particles to model a variety of multiphysics problems. Several of the coupling features are used in predefined multiphysics interfaces but can also be added manually. Except for the coupling features between AC/DC interfaces, most of the coupling features require additional licenses of other modules such as the Structural Mechanics Module.
