本文提出了一种基于离散电磁场的非结构网格上的准静电场有限元计算方法。所提出的配方考虑了介电效应以及非线性导电效应。该实现是基于非结构化的3-D网格上的离散微分形式。数值模拟的三维线性和非线性材料组成的高压避雷器的结果示出。将代数多重网格方法引入非标准投影预处理共轭梯度线性方程组求解器
A finite-element formulation based on a discrete electromagnetism is developed to simulate electro-quasistatic fields on unstructured meshes. The presented formulation takes dielectric effects into account as well as nonlinear conductive effects. The implementation is based on discrete differential forms on an unstructured 3-D mesh. Numerical results of the simulation of a three dimensional high-voltage surge arrester consisting of linear and nonlinear materials are shown. An algebraic multigrid method is introduced as a preconditioner to nonstandard projected preconditioned conjugate-gradient linear system solver
