Abstract: The modeling of eddy currents in conductors is split into a sequence
of progressive finite element subproblems. The source fields generated by the
inductors alone are calculated at first via either the Biot-Savart law or
finite elements. The associated reaction fields for each added conductive
region, and in return for the source regions themselves when massive, are then
calculated with finite element models, possibly with initial perfect 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.
