摘要

本文介绍了自由分布软件FreeFem++应用有限元法求解电动力学内边值问题的结果。为了建立图形模型，建议使用免费分发的3d编辑器Blender。利用FreeFem++开发了具有复杂边界面的周期性结构的电动力学特性自动计算脚本。基于实验数据对特征频率计算的精度进行了估计，并与商业程序Ansys HFSS进行了比较，结果表明自由软件具有较高的精度和效率。

Use of a Free Software to Solve Internal Boundary Problems of Electrodynamics with a Method of Finite Elements

The results of the application of freely distributed software FreeFem++ for solving internal boundary value problems of electrodynamics by the finite element method are presented. To build graphical models, it is proposed to use the freely distributed 3D-editor Blender. Scripts have been developed to automate the calculation of electrodynamics characteristics of periodic structures with complex boundary surfaces using FreeFem++. The estimation of the accuracy of the eigenfrequency calculation based on the experimental data and in comparison with the commercial program Ansys HFSS showed high accuracy and efficiency of free software.
