Equation: Magnetodynamic¶
In one sentence: Elmer equation for time-harmonic (AC) electromagnetic fields — computes magnetic field, eddy currents, and Joule heating.
Overview¶
Workbench: FEM
Menu: FEM → Solve → Elmer Equations → Magnetodynamic
Solves the time-harmonic (AC, frequency-domain) Maxwell equations for the magnetic vector potential A. Computes magnetic field, eddy currents, and Joule heating in conductors.
Required¶
- BCs: Magnetization or Current Density on source regions
- Material: Electrical conductivity, relative permeability
Use cases¶
Induction heating, transformer core analysis, eddy current braking, wireless power transfer.
