有限单元法数据生成器

本文介绍有限单元法数据生成器采用字符标识的输入数据系统和等参元插值函数的概念,人工准自动或全自动生成实际工程问题二维或三维有限元分析所需要的基本数据,如单元节点号、材料参数、节点坐标、边界条件和荷载信息等等。这个数据生成器以统一的程序和相同的输入方式来处理规则网格、不规则网格,以及它们的任意组合和各种类型的单元,便于用户的使用。

FEM Data Generator

The FEM data generator presented in this paper is used to generate quasi-automatically or automatically the basic data for 3-d or 2-d finite element analysis of engineering projects, such as element nodal connections, material parameters, nodal coordinates, restrained boundary conditions, and the information of applied load. With the symbol-identified input data system and the concept of interpolation function of isoperimetric element, this data generator deals with regular meshes, irregular meshes, and their arbitrary combination in unified routine and the same way to input data, which is available to any kind of elements and convenient to users. The work principle of this data generator and the features of corresponding computer routines are described in detail.
