关于流固耦合在ANSYS建模中的实现!
例子 Example Fluid-Structural Analysis Using Physics Environments The example in this section illustrates a steady-state fluid-structure interaction problem. This problem demonstrates the use of nonlinear large-deflection structural coupling for a fluid domain as well as the use of the "null" element type in a physics environment setting. It also demonstrates mesh morphing.问题描述：A channel containing a rubber gasket is subjected to water flowing with an inlet velocity of 0.35 m/sec. (See Figure 5.8 below) The object of the problem is to determine the pressure drop and gasket deflection under steady-state conditions. The problem is completely described by the input listing provided at the end of this section.
在操作过程中，感觉网格划分处出了问题，但是找不出问题，附图。http://forum.vibunion.com/forum.php?mod=image&aid=62590&size=300x300&key=32abe8a86c3cb5686c75c73065b8f6e0&nocache=yes&type=fixnonehttp://forum.vibunion.com/forum.php?mod=image&aid=62590&size=300x300&key=32abe8a86c3cb5686c75c73065b8f6e0&nocache=yes&type=fixnone这图是我在进行Solve with FLOTRAN.Command(s): SOLVE
GUI: Main Menu> Solution> RunFLOTRAN 这步操作后出现的，前面划分网格是好像也跳出了一个警告。这个例子里面，我搞不懂"null"element type的用法，希望有高人给我一一指教，小弟感激不尽。谢谢！http://forum.vibunion.com/forum.php?mod=image&aid=62592&size=300x300&key=5cad024be263d6faa575c94394ee2596&nocache=yes&type=fixnone
怎么没人参与呀！我在划分gasket的网格时碰到第一个问题，出现了一个警告。如图http://forum.vibunion.com/forum.php?mod=image&aid=62594&size=300x300&key=53923adf820a169a5ac8cf83cbe5c2a1&nocache=yes&type=fixnone
