The Electromagnetics Interfaces
For simulating electromagnetic fields, COMSOL Multiphysics has three physics interfaces.
•
Electrostatics
•
Electric Currents
•
Magnetic Fields
With the first two, you can perform static simulations to solve for electric properties in all space dimensions.
For 2D axisymmetric and 2D geometries, you can use the Magnetic Fields interface to perform magnetostatic simulations. The 3D Magnetic Fields interface is available in the optional AC/DC Module.
This section begins with a brief introduction to electromagnetics and a definition of the electromagnetic quantities. Then it describes each of the physics interfaces in detail.
The optional AC/DC Module contains specialized and extended interfaces for electromagnetic simulations, for example, for computations of inductors and capacitors. The optional RF Module includes interfaces for simulating electromagnetic wave propagation that are especially useful in microwave engineering and photonics.
