Abstract

This paper presents a new algorithm based on the indirect boundary integral equation method (BIEM) to analyse electromagnetic systems with moving conductors. The proposed algorithm yields relatively stable and accurate solutions because a fundamental Green´s function of diffusion type is used which is valid for any value of the Peclet number. In addition, computer memory and computing time for 3D computation can be saved considerably by using the boundary integral equations of minimum order and the singular property of the Green´s function. In order to prove this, numerical results obtained by the proposed algorithm and the upwind finite element method are compared with their analytic solutions
