An energy-based error criterion for transient electrodynamical applications
Résumé
A quadratic energy-based error criterion is derived from a thermodynamic description of electromagnetism. Attention is first paid on the analytical derivation of the criterion in a general sense, i.e. without any assumption about the potential formulation and including possible body motion. Some validations are given on actuator and induction heating process within the FEM: The conservation of the electromagnetic power is assessed locally and, as expected, the ill-checked elements in the skin depth are highlighted.
