| 摘 要： | 采用数化仪直接输入有限元结构分析的网格图数据有很大的优越性,它避免了采用一般的间接输入方式时可能出现的差错。 本文论述了利用数化仪输入图形的基本概念,并介绍了笔者开发的数化仪前处理程序GNDGTZ的主要功能。着重讨论了几个关键问题,即第3座标的输入、结点的生成、结点的即时显示、单元的数化、空间模型的单元输入和单元的生成。

| Abstract: | It is very advantageous to input the mesh data for a FEM structural analysis through a digitizer directly. Some mistakes which may occur when input by the conventional indirect methods can be avcied.In this paper, the basic concept of graphic input through a digitizer is described and the chief functions of a digitizer pre-processor program GN-DGTZ developed by the author are introduced. Among them are some key problems, such as inpnt of the third coordinate, generation of nodes, instant: display of nodes, digitizing of elements, input of element in the 3D mode and generation of elements. |
