A T, Φ−Φ Multiscale Finite Element Formulation for Eddy Current Problems in Open Magnetic Circuits

Abstract

The multiscale finite element method has shown its high potential for the simulation of the eddy current problem in closed magnetic circuits with laminated cores. This work presents a new approach developed to extend the multiscale finite element method to open magnetic circuits. To this end, a three dimensional eddy current problem with the novel T,F- F multiscale formulation and linear material relations has been studied. Numerical results demonstrate the high accuracy of the presented method.
