The grid velocity is obtained by using both of so - called laplace and velocity relaxation methods , and rezone is automatically done . the remap of state variables is calculated with both of donor cell and linear interpolation method 采用laplace反演方法和速度松弛法計(jì)算網(wǎng)格速度,實(shí)現(xiàn)了網(wǎng)格的自動重分,采用貢獻(xiàn)網(wǎng)格法和線性插值完成輸運(yùn)計(jì)算。
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(shù)的發(fā)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(yīng)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(shí)現(xiàn)任意剖面上可視化處理,必須先將得到的有限元計(jì)算結(jié)果進(jìn)行再處理,因此在算法上分為兩部分:求任意剖面上物理量值的算法及二維等值線算法。前一部分以彈性力學(xué)中“任意斜截面的應(yīng)力”為理論基礎(chǔ),利用線性插值方法得到截面與單元棱邊的交點(diǎn)坐標(biāo)及交點(diǎn)物理量值;在此基礎(chǔ)上;根據(jù)已得到的單元及節(jié)點(diǎn)序號表、應(yīng)力應(yīng)變物理量表,總結(jié)出一種基于有限元剖分網(wǎng)格的快速生成二維等值線的算法。
3d linear interpolation method was used to transform displacement and force data between fluid and solid structure meshes in an indirect fluid - solid interaction simulation . by computing an axial - flow compressor blade , results show that 3d linear interpolation method is an effective method and indirect fluid - solid interaction suit for engine blade simulation . software integration is feasible method for coupling 提出一種對發(fā)動機(jī)葉片及通道進(jìn)行氣動、結(jié)構(gòu)的間接流固耦合交替計(jì)算方法,并采用三維線性插值方法對ansys和fluent中的網(wǎng)格數(shù)據(jù)進(jìn)行變換,并對不同材料和不同轉(zhuǎn)速葉片的模型進(jìn)行流固耦合計(jì)算,結(jié)果表明三維線性插值方法是一種簡單、計(jì)算量小、可行的數(shù)據(jù)交換方法。
