我们提出了一个最近发展的多重网格计算方案耦合磁力机械系统。该方案允许三维（3-D）的动态刚性运动以及变形的磁性和铁磁材料在磁场中的有效计算。因此，三维力学问题用节点单元离散，三维磁问题用棱边单元离散。两个有限元网格都可以独立地选择，因此可以分别适应机械场和磁场的物理要求。快速多重网格求解技术可以在很短的CPU时间内解决大规模的三维问题。三个例子证明了该方案的有效性。
We present a recently developed multigrid calculation scheme for coupled magnetomechanical systems. The scheme allows the efficient calculation of three-dimensional (3-D) dynamic rigid motions as well as deformations of nonmagnetic and ferromagnetic materials in a magnetic field. Thereby, the 3-D mechanical problem is discretized with nodal elements and the 3-D magnetic problem with edge elements. Both finite element meshes may be chosen independently and thus can be separately adapted to the physical requirements of the mechanical and magnetic fields. Fast multigrid solution techniques can solve large scaled 3-D problems within very short CPU times. Three examples demonstrate the efficiency of the developed scheme.
