Eddy Current Solver

The eddy current (AC magnetics) field simulator computes electromagnetic fields in the frequency domain in 2D or 3D. The sources of the electromagnetic field can be

AC currents in conductors.
Time-harmonic external magnetic fields represented by boundary conditions.

The quantity for which the eddy current field simulator solves is the magnetic field, H. The magnetic flux density, B, is automatically calculated from the H-field.

Optionally, the eddy current solver can incorporate displacement currents into the solution even in non-conducting domains, thereby allowing the solution of the full system of Maxwell's equations and the recovery of the electric field E everywhere including the non-conducting regions. Derived quantities such as forces, torques, energy, losses, and impedances may be calculated from these basic field quantities at the solution frequencies.

In 2D, only the A-F formulation is available. However, in 3D, both T-W and A-F formulations are available and can be selected from the Solver Type window:
