Abstract :
[en] A procedure is proposed to deal with magnetic vector potential finite element magnetodynamic formulations and the definition of their associated circuit relations, involving voltages and currents, especially for massive inductors. It consists in solving two successive problems thanks to the use of edge elements, the first problem releasing the second one, which is especially useful for efficient nonlinear time stepping analyses
