摘要：

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.
