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
縱觀有限元分析技術的發展，目前大多集中在建立良好的用戶界面上的研究仍存在許多應用上的局限性，其中對任意剖面上可視化的研究仍處于方興未艾的階段。要實現任意剖面上可視化處理，必須先將得到的有限元計算結果進行再處理，因此在演算法上分為兩部分：求任意剖面上物理量值的演算法及二維等值線演算法。前一部分以彈性力學中「任意斜截面的應力」為理論基礎，利用線性插值方法得到截面與單元棱邊的交點坐標及交點物理量值；在此基礎上；根據已得到的單元及節點序號表、應力應變物理量表，總結出一種基於有限元剖分網格的快速生成二維等值線的演算法。 -
