摘要：

A modification method of finite element meshes based on the adaptive meshing for optimization of electric machines is proposed. In the optimization process of the machine, the proposed method generates the mesh for the new shape from the previous mesh with minor modification. The locations of the nodes for the new shape are decided by solving the Laplace's equation, whose unknowns are displacements of the nodes. The advantages are clarified by the application to the shape optimization of an IPM motor.
