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.

It passes the Lorentz force from the Magnetic Fields interface to the Solid Mechanics interface and, passes the induced electric field from the Solid Mechanics interface to the Magnetic Fields interface. The Lorentz force effect on a moving structure is similar to that of the Rayleigh alpha-damping, where the damping coefficient is proportional to the background magnetic field and the material electric conductivity.
