针对三维涡流问题，提出了一种不使用拉格朗日乘子的有限元迭代程序，该迭代程序基于从静磁问题的摄动问题导出的迭代程序。为了考虑励磁电流密度的连续性，还提出了一种校正方法。数值结果表明，双共轭梯度（BiCG）方法适用于迭代过程中产生的复杂对称线性系统，并且近似物理量是合适的。
An iterative procedure using finite element method without the Lagrange multiplier is proposed for three-dimensional eddy current problems, which is based on an iterative procedure derived from a perturbation problem of the magnetostatic problem. To consider the continuity of an excitation current density, a correction method is also proposed. Numerical results show that the BiConjugate Gradient (BiCG) method is applicable to the complex symmetric linear systems arising in the iterative procedure, and that approximate physical quantities are suitable.
