An efficient mesh reconstruction method for optimizing the shapes of electromagnetic devices using finite element method

An efficient mesh reconstruction method is proposed for remeshing the parameterized computation domain when using finite element method to optimize the shapes of electromagnetic devices. The proposed method has the merits of conserving the original structure of the mesh with minimal mesh deformation. The proposed method has been applied to TEAM workshop problem No. 25 and a permanent magnetic (PM) DC motor parameter optimization study. The reported results are used to validate the efficiency and validity of the method.
