First Approach on a Mixed Domain Decomposition Method for 2-D Magnetostatic Simulation of Electrical Machines

A mixed domain decomposition method (DDM) is presented in this article. This method falls within the needs of advanced numerical optimization of electrical machines. Thus, we aim to adapt the LATIN method to the magnetostatic equations, as it has been so far mainly used for mechanical studies. The method provides a powerful iterative scheme that relies on mixed writing of the equations on the domain interfaces, including both primal and dual fields. The method is presented in detail in this article, and its performances are evaluated on a first implementation for the simulation of Team Problem No. 24.
