摘  要:结合近年来的科研工作,讨论了若干棱边有限元法在工程涡流分析中的应用问题,如棱单元矢量插值函数的统一导出方法、树规范问题、大型稀疏方程组迭代解法以及电磁场直接求解方法的研究,并比较了棱边有限元法与传统的节点有限元法各自的优劣。最后给出了待解决的问题。Based on the research work done by the authors in recent years, some applications of edge element method in the numericalcomputation of power eddy current problems are introduced, such as the unified derivation of interpolating functions, gauging problems, the iterative algorithm for the large sparse equations, and the direct method in the numerical analysis of electromagnetic field. The evaluation of edge element method is given and it's pointed out that the edge element method and traditional nodal element method have their own advantages and disadvantages respectively. At last, the further work to be solved is presented.
