| 摘 要： | 求解表述各类边值问题的偏微分方程,有限元法定一种较有效的数值解法。文章描述了三维有限元计算常用的两种有限元——三棱柱单元和六面体等参元的自动生成原理,建立了相应的数据前处理软件。该软件采用了适当的图形处理方法,克服了应用有限元法的困难,只需直观地输入较少量的数据,就可形成有限元分析所需的各类信息,并能对剖分结果进行多种形式的二维和三维图形显示。

| Abstract: | Basic theory of mesh automatic generation of two kinds of element: triangle prism and hexahedron is given in the paper.And also associated software for the data pre-processor. A proper graphic treatment method has been used, thus the inconvenient of huge input data prepared is avoided in the finite element method.Now a few data is to form the mesh data which includes all necessary relevant informations and also three dimensional graphic can be seen on screen or hard copy.And mesh data are stored in an appreciate data file. |

| Keywords: | Finite element analysis Automatic mesh generation Isoparametric coordinate transformation Graphic display |
