圆柱体内静电场有限元分析与计算

Analyses and Calculations of Static Electricity Field in Cylinder by FEM

重点讨论了电磁场三维等参数有限元算法的基本原理及实现过程．利用ＷＩＮＤＯＷＳ强大的内存管理功能，使程序可进行大型的运算，剖分的单元、节点可达上百万个．在整个三维空间进行单元网格自动剖分，解决了人工剖分工作量大且易出错的问题，使这一工作具有很强的实用意义．文中所讨论的工作还利用了当前先进的ＷＩＮＤＯＷＳ编程技术，使得人机界面非常友好，可直接应用于圆柱体内电磁场的三维优化设计、电缆性能分析、设计及其它相近的场合．

This paper discusses the fundamental of 3D FEM algorithm.Taking advantage of memory management functions of WINDOWS operating system,a large scale program can be run.The number of cells can be as many as several millions or more,and the cells are segmented automatically,which solves the problems of manual work and makes the works be of practical significant.By means of Windows's programming technology,friendly appearance is made.The results of this paper can be applied to electric magnetic field design on three dimensions and analysis of cable performance as well as other applications.
