Abstract

A subproblem method with a finite element magnetodynamic formulations are developed for correcting the inaccuracies near edges and corners arising from using thin shell models that replace thin volume regions by surfaces. The surface-to-volume correction problem is defined as one of the multiple subproblems (SPs) applied to a complete problem, considering sucessive additions of inductors and magnetic or conducting regions, some of these being thin regions. Each SP is solved on its own separate domain and mesh, which facilitates meshing and solving while controlling the importance and usefulness of each correction.
