摘要
提出一种计算三维线性涡流场的三分量边界元算法。该算法采用在导体表面上虚设的磁荷和电流密度为求解变量，仅需求解３个分量：虚设磁荷标量和电流密度矢量的２个分量。相对于一般的四分量法（即采用１个标量和１个三分量矢量为求解变量的算法），该三分量法可以节省约４０％的计算机内存和５０％的计算时间。
A three component boundary element algorithm for the calculation of 3 d linear eddy currents is presented,which employs an imaginary magnetic charge scalar and an imaginary current density vector with two components,distributed over the interfaces of different regions,as unknowns.This reduction of one component can save about 40% computer memory and 50% computer time in the solution relative to ordinary four component algorithms.
