An Energy Based Approach of Electromagnetism Applied to Adaptive Meshing and Error Criteria

In order to improve the finite-element modeling of macroscopic eddy currents (associated with motion and/or a time-varying electrical excitation), an original error criterion for adaptive meshing, based on a local power conservation, is proposed. Then, the importance of the order element in the error computation is investigated. Finally, the criterion is coupled to a ldquobubblerdquo mesh generator, and an adaptive meshing of a 2D induction heating case is performed.
