Examples
- Pst denotes optical system capability of suppressing stray light , and brdf represents material surface scatter and reflectance property . these two physical values are the base of stray light analysis and calculation
表示光学系统杂光抑制能力的点源透过率pst和材料表面散射特性的双向反射分布系数brdf ，这两个物理概念是光学系统杂光分析与计算的基础。 - Perfect pre - processing and post - processing function is one of the main factors to evaluate the vitality and market value of the finite element analysis system surveying today development of finite element analysis technology , most of which concentrate on establishing fine user interface , also has some limitation on application , and especially , the research on the visualization of arbitrary cut - plane is always in ascendants to realize the visual processing on cut - plane needs reprocessing the results of finite element analysis which have get , so the algorithm is two parts : seeking the physical value of cut - plane and drawing 2d contours , , the former , based on the theory of stress on " arbitrary inclined plane " in physical mechanics , use the method of linear interpolation method to get the coordination and physical value of intersection between cut - plane and element arris ; the latter , based on the tables on elements , nodes , stress and strain , summarize a rapid algorithm of generating 2d contours based on the grid . this thesis synthesizes there two parts and get a visual processing program under fortran
纵观有限元分析技术的发展，目前大多集中在建立良好的用户界面上的研究仍存在许多应用上的局限性，其中对任意剖面上可视化的研究仍处于方兴未艾的阶段。要实现任意剖面上可视化处理，必须先将得到的有限元计算结果进行再处理，因此在算法上分为两部分：求任意剖面上物理量值的算法及二维等值线算法。前一部分以弹性力学中“任意斜截面的应力”为理论基础，利用线性插值方法得到截面与单元棱边的交点坐标及交点物理量值；在此基础上；根据已得到的单元及节点序号表、应力应变物理量表，总结出一种基于有限元剖分网格的快速生成二维等值线的算法。
