摘要
本文在优化区域边界的二维电磁场逆问题中,应用高阶有限元,增大了可变动节点的变化范围。消去中中间变量,采用分块矩阵,使优化变量对应的雅可比矩阵阶数大为降低,节省了计算机内存和计算时间。本文方法曾用于凸极电机磁极形状优化设计。
For two dimensional inverse electromagnetic field problems,the range of movable points is extended by use of high order finite elements. The order of the Jacobian matrix is much reduced by eliminating median variables. By using the technique of partitioning of matrices,the calculation is simplified.As a result, the computer storage and compution time are saved. The presented method has been used to optimaze pole shape of a salient-pole synchronous generator.
