有限要素法による三次元渦電流解析

Finite element method using edge element have been developed and utilized for practical eddy current analysis. In this paper, a finite element analysis using an edge element which is based on linear functions is described. Two programs were developed for eddy current analysis. One uses the reduced magnetic vector potential technique for taking account of a source current density. Another uses the current segment as source. The programs were applied to a benchmark problem, which was proposed by TEAM (Testing Electromagnetic Analysis Methods) workshop. The validity and the advantage of the developed programs are discussed
