First approach of a mixed domain decomposition method for magnetostatic simulation of rotating machines

In this work, a mixed domain decomposition method (LATIN) is proposed to improve the efficiency of magnetostatic simulation of rotating machines. This strategy relies on a decomposed formulation of the problem considering both primal and dual fields on the interfaces. From this formulation, the LATIN solver method gives a powerful iterative scheme to build a solution. A first implementation using the magnetic vector potential formulation in 2D is developed and is illustrated on two test cases: a ferromagnetic 2D bar and a switched reluctance motor.
