A parallel implementation of a mixed multiscale domain decomposition method applied to the magnetostatic simulation of 2D electrical machines

Abstract

This article introduces a mixed domain decomposition method (DDM) designed to meet the requirements of advanced numerical optimization in electrical machines. The primary objective is to adapt the multiscale LATIN method, primarily used for mechanical studies, to the magnetostatic context. The proposed method offers an effective iterative scheme that relies on a mixed formulation of the equations on the domain interfaces, considering both primal and dual fields. A parallel computation strategy for the algorithm is implemented. Computational experiments performed demonstrate the scalability and efficiency of the algorithm.
