BOUNDARY ELEMENT ANALYSIS FOR THE 3-DIMENSIONAL EDDY-CURRENT PROBLEM

The numerical implementation of the boundary element method formulated for the three-dimensional eddy current problems is presented. In particular, the algorithm for solving this problems together with the formulation for the magnetic vector potential A and the electric potential Φusing the Lorentz's gauge are discussed in detai1. Next due to accurate calculations of the numerical solution at interior points in the neighborhood of the boundary, the revised integration method [1] is expanded to this three-dimensional magnetic field analysis for steady-state. It is indicated that our method is available in the eddy current analysis. © 1990, IEEE. All rights reserved.
