Abstract

The A-φmethod by means of finite element approximation has been applied far and wide in the quasi-magnetostatic eddy current computation in the last two decades.However, the literature on the error estimates of this method can not be found so far yet.This provides a convergence analysis of A-φmethod for 3D eddy-current problems based on ungauged potentials by means of finite element approximation.Error estimates of the proposed method are given under the appropriate regular conditions.
