提出了一种用于移动设备的有限元模型的新技术。使用拉格朗日乘子将独立网格与合适的接口（例如常规电机的气隙）耦合在一起。该方法允许有限元网格相对于相邻网格移动，而无需重新划分网格。在不同的位置，只有在界面处将网格耦合在一起的项被改变。虽然只有在不同的时刻产生许多不同的静磁解决方案或“快照”的转子的问题在这里得到解决，作者预计，处理速度感应涡流在时间瞬变的情况下，应该是可能的，通过扩展相同的基本技术。>
A novel technique for use in finite-element models of devices which move is proposed. Independence meshes are coupled together with a suitable interface, such as the air gap of a conventional electrical machine, using Lagrange multipliers. The proposed approach allows a finite-element mesh to move with respect to an adjacent mesh without any need for remeshing. At different positions, only the terms which couple the meshes together at the interface are altered. While only the problem of producing many different magnetostatic solutions or 'snapshots' of the rotor at different instants in time is addressed here, the authors expect that treating velocity-induced eddy currents in a time-transient situation should be possible by extending the same basic techniques. >
