| Abstract: | An iterative method is proposed for a finite element approximation of three-dimensional eddy current problems. The method is based on an iterative method derived from a perturbation problem of magnetostatic problems. The TEAM model and a transformer model are considered as numerical examples. In both examples, BiConjugate Gradient (BiCG) method is applicable for the complex symmetric linear system arising in each step of the iterative procedure for a rather wide range of the perturbation parameter, and the present results seem to be suitable. |
