提出了一种计算退磁场的有限元-边界积分混合法。对于在磁区中具有N个节点的三维（3-D）网格，该方法需要存储O（N/sup 4/3/），并且不需要考虑磁区之外的节点。该方法适用于非线性计算，可以适应于处理弯曲的边界，特别是当磁性区域由几个部分，其相对位置是可变的方便。<>
A hybrid finite-element-boundary integral method is proposed for computing demagnetizing field. For a three-dimensional (3-D) mesh with N nodes in the magnetic region, the method requires storage O(N/sup 4/3/), and no nodes outside the magnetic region need to be considered. The method is suitable for nonlinear calculations, can be adapted to handle curved boundaries, and is especially convenient when the magnetic region consists of several parts whose relative positions are variable.<>
