Electromagnetics

Analyze solutions of static and time-harmonic electromagnetic problems

Perform electrostatic, magnetostatic, DC conduction, or harmonic analysis for the design of electrical and electronic components. For details about partial differential equations for electromagnetics, see:

The solver returns one of the results objects containing the solution values, such as electric or magnetic potentials, fields, and flux densities, at mesh nodes. After solving the problem, you can interpolate returned results to arbitrary spatial locations instead of mesh nodes.
