Solve PDEs that model static and time-harmonic electric and magnetic fields. A typical programmatic workflow for solving an electromagnetic problem includes these steps:
Create a special electromagnetic model container for an electrostatic, magnetostatic, or harmonic analysis.
Define a geometry and mesh it.
Assign electromagnetic properties of the material, such as relative permittivity, relative permeability, and conductivity.
Specify charge density, current density, and magnetization within the geometry.
Specify voltage, magnetic potential, surface current density, and an electric or magnetic field on the boundaries.
Specify absorbing boundary conditions.
Solve and plot results, such as the resulting electric or magnetic potentials, fields, and flux densities.
