基于AutoCAD平台的有限元后处理系统开发

摘要

有限元后处理是开展有限元分析的重要步骤，同时也是衡量一个有限元软件是否成功的重要因素。基于AutoCAD平台的DXF格式，对有限元后处理程序开发中的关键技术问题展开了研究，构建了基于AutoCAD平台的有限元后处理系统，并且结合面板堆石坝给出了应用实例。研究表明，基于AutoCAD平台的有限元后处理系统能直接与计算程序相连接，生成的DXF格式后处理文件可直接在AutoCAD平台下编辑，不需要额外编写程序代码来执行图形处理操作，可满足使用者个性化的显示要求，可为有限元计算分析提供便捷高效的后处理平台。%The finite element post-processing is a key step for finite element analysis and also an important factor to judge performance of finite element software. Based on the DXF file format of AutoCAD Platform, the key issues for the program devel-opment of finite element post-processing are studied, and a system for finite element post-processing is established and applied to a face rockfill dam calculation. The study shows that the post-processing of finite element method based on AutoCAD Platform can be directly linked with calculation program, and the post-processing DXF file format generated by the system can be directly edited in the AutoCAD Platform. It is unnecessary to write additional programming codes to perform graphics processing opera-tions and fulfill the personalized requirements of graphic display, which provides a convenient pos-processing platform for finite element analysis.
