Overview of Electromagnetics-Fluid Interaction Interfaces
The Model Wizard and the Add Physics window contain a number of multiphysics interfaces for modeling fluid interaction with magnetic and electromagnetic fields, all available under the Electromagnetics and Fluids branch () within the AC/DC branch (). This section gives an overview introduction to these multiphysics interfaces. The multiphysics interfaces for electromagnetics-fluid interaction are described in the subsequent sections:
•
The Magnetohydrodynamics Interface (): Combines the Magnetic and Electric Fields and Laminar Flow to model the interaction of magnetic fields and conducting fluids in 3D. The magnetic fields are solved with the Magnetic and Electric Fields interface, which includes the solving of a current conservation equation.
•
The Magnetohydrodynamics, In-Plane Currents interface (): Available in 2D and 2D axisymmetric, it has the same settings as The Magnetohydrodynamics Interface.
•
The Magnetohydrodynamics, Out-of-Plane Currents interface (): Available in 2D and 2D axisymmetric, it shares most of the settings with The Magnetohydrodynamics Interface. The difference is that the magnetic field is computed with the Magnetic Fields interface, which does not solve a current conservation equation. This interface is used here since it is computationally cheaper than the Magnetic and Electric Fields interface.
