Abstract

� 2016 IEEE. For three-dimensional (3-D) large-scale problems, iterative solver is preferable due to a huge amount of memories are needed if the direct linear solver is adopted. In this paper, a novel Coulomb-gauged formulation for magnetostatic problems using edge element is first proposed. For the proposed formulation, the resultant linear system is symmetric and well-conditioned. It can be solved by iterative solver efficiently. A numerical example is presented to showcase the efficiency of the proposed method for practical engineering computation.
