Electromagnetics
Solve problems that model electric and magnetic fields
Solve PDEs that model static electric and magnetic fields. A typical programmatic workflow for solving an electromagnetic problem includes the following 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 or current density within the geometry.
Specify voltage, magnetic potential, 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.
