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。这图是我在进行Solve with FLOTRAN.Command(s): SOLVE
GUI: Main Menu> Solution> Run FLOTRAN 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!
