摘要
有限元法和无网格法在电磁场数值计算中已经得到了广泛的应用,然而有限元法存在前处理网格剖分问题,无网格法存在计算时间长、边界条件和不连续面难处理等问题。针对以上问题,本文提出了利用自然单元法求解电磁场的方法,该方法根据场域中的离散点的信息构造自然邻点插值函数,最后算出场值。通过算例证明了该方法在电磁场计算中的可行性。
Finite element method and nomesh method in the numerical calculation of electromagnetic fields has been widely used, however, there are problems of pre - processing finite element method, mesh generation, long time grid computing , boundary conditions and discontinuities refractory issues. To solve the above problem, this paper presents the natural element method used to solve electromagnetic field method in the Field of discrete points according to the information structure of natural neighbor interpolation function, the value of the final count appeared. A numerical example verifies the feasibility of electromagnetic field calculation method.
