SUBPROBLEM FORMULATIONS BASED ON MAGNETIC FIELD AND SCALAR POTENTIAL VECTORS FOR CORRECTING THIN SHELL MODELS

Abstract

The propose of this paper is based on subproblem formulations with a magnetic field and scalar potentials to compute and simulate the distribution of fields (magnetic fields, magnetic scalar potentials, eddy currents and Joule power losses) appearing from thin shell models, where it is somewhat difficult to use directly finite element method formulations. The scenario of the method is to couple subproblems in two steps: A subproblem consisting of the stranded inductor and thin shell model is first considered. The following subproblem with actual volumes (including one or two conductive regions) is added to improve errors near edges and corners of the thin shell models. All the steps are independently performed with different meshes and domains, which facilitates meshing and reduces computation time for each sequence.
