摘要
提出了有限元数值求解三维涡流场的一种新的迭代解法,该解法将传统的涡流场数值求解过程分成磁场计算与涡流计算两步,并进行迭代直至收敛。由于该解法所形成的系数矩阵是阶数较低的实矩阵,而且在迭代过程中只需进行一次消元或分解,从而显著降低了计算机内存和计算时间。实例计算表明该解法对大型工程涡流问题具有较高的计算效率。
This paper presents a new iteration method for solving three dimensional eddy current fields. The method features that the numerical calculation of fields can be divided into two steps: magnetic field and eddy current calculations, in which an iteration procedure is used to obtain field solutions. Because the stiffness matrices containing relatively few variables formed in the method are real and eliminated only one time in the iteration procedure, the computer resource can be saved. It has been shown by the examined examples that the presented method is of high calculation efficiency for the large-scale eddy current problems in engineering.
