Progressive Source and Reaction Fields for Magnetodynamic Model Refinement via a Finite Element Subproblem Method
Résumé
Magnetodynamic models are split into a sequence of progressive finite element subproblems. The source fields generated by the active conductors alone are calculated at first via either finite elements or the Biot-Savart law. The associated reaction fields for each added magnetic and/or conductingregion, and in return for the source regions themselves when massive, are then calculated with finite element models, possibly with initial perfect magnetic, conductor and/or impedance boundary conditions to be further corrected. The resulting subproblem method allows efficient solving of parameterized analyses thanks to a proper mesh for each subproblem and the reuse of previous solutions to be locally corrected. Accuracy improvements are obtained for local fields and global quantities, i.e. inductances, resistances, Joule losses and forces.
