【摘要】 文章在现有的有限元本体程序和产品数据交换国际标准STEP的基础上,提出一种通用的有限元数据交换模型。以集成资源STEP/AR104为基础构建一个能满足有限元后处理需要的数据核,来实现有限元分析本体程序和后处理系统之间的数据交换,并用OpenGL对其数据进行可视化。利用STEP中性文件机制,可以实现后处理系统与多个有限元分析本体程序之间的连接。更多还原

【Abstract】 This paper presents an exchange model of Finite Element data on the base of the Finite Element Analy sis program and an International Standard of product data exchange-STEP.In ord er to carry out data exchange needs be-tween the Finite Element Analysis prog ram and postprocessing systems of Finite Element Analysis,it designs a data s tructure on the base of the integrated application resource STEP/AR104,whic h can meet the needs of dealing with postprocessing systems of Finite Element Analysis,and then visualize these data using OpenGL.Using STEP neutral mechani sm,the authors can connect a postprocessing system of FEA with some Finite Ele ment Analysis programs.更多还原
