摘要
针对开域空间磁场计算问题，提出了求解二维开域电磁场问题的一种新解法。这种解法可以将开域磁场的场域缩小到包含所有铁磁媒质和电流区域的最小圆形范围，而问题的结果可以覆盖整个开域空间。计算分析表明，这种方法实现简单，只需求解圆形区域的有限元方程和边界方程，所需计算内存和ＣＰＵ时间都很小。
New approach to solving D electromagnetic field in open space is presented in thispaper, which restricts calculation region into a small round area and gets solutions of whole space. The method is implemented simply by solving FE equations and boundary equations in circular area. Its storage and CPU time are very small. Calculation shows its validity.
