Finite Element Implementation of the Iterative Scalar Potential Method for the Computation of Eddy Currents

Finite Element Implementation of the Iterative Scalar Potential Method for the Computation of Eddy Currents

Eddy currents are computed by iteratively solving for scalar potentials describing the magnetic and electric fields. The necessary vector potentials in the conducting domain are constructed in a cheap way from the fields obtained in the previous iteration. Convergence without relaxation is achieved...

Zusammenfassung:Eddy currents are computed by iteratively solving for scalar potentials describing the magnetic and electric fields. The necessary vector potentials in the conducting domain are constructed in a cheap way from the fields obtained in the previous iteration. Convergence without relaxation is achieved for low frequencies, while for higher frequencies, under-relaxation is used.
