摘要
本文导出了具有各向异性媒质时三维涡流问题的矢量磁位—标量电位法有限元离散化格式,讨论了消去标量电位的条件。通过实际算例研究了忽略标量电位所引起的误差,用解析解答验证了三维数值解的正确性。
In this paper, the FE discretized equations of magnetic vector potential and electric scalar potential in 3D-eddy current problems of anisotropic medium are derived. The conditions under which the electric scalar potential can be eliminated are discussed. The errors resulting from the neglecting the electric scalar potential are analysed using numerical models. The 3D-numerical solution is verified by the analytic solution.
