This paper proposes a coupled finite element analysis of magnetic and thermal fields using object-oriented and adaptive single-mesh methods. A fine mesh is built for both magnetic and thermal analysis to avoid errors of data transfer and mesh reconstruction. An adaptive meshing method based on master-slave definition is employed to simplify the origin mesh into magnetic and thermal mesh according to their field characteristics. Object-oriented method is used for a flexible customization in programming architecture. A permanent magnet machine is introduced to test the proposed coupled analysis method.
