Abstract: In this paper, a new method for mesh refinement in Surface Current Method (SCM) based on combination of uniform and automated mesh refinement is proposed. This method is a fast and accurate method related to the usual SCM mesh refinement method. In this refinement method the ferromagnetic boundaries are divided in to the two sub-boundaries which are called outside and inside boundaries. The outside and inside boundaries are refined by uniform and automated mesh refinement respectively. Therefore the total number of meshes which obtained in this method will be lower than classical SCM refinement. Verification of simulation results is done using Finite Element Method (FEM).
