考虑碰撞的流固耦合问题

lich_615

主题：一个金属水箱，里边有纵、横隔板，里边装80％水，考虑碰撞的流固耦合。
问题：
      1，水箱是SHELL单元，建模时需要模型简化，模型简化需要注意什么？
      2，我听到有人说要提取中面，什么是“提取中面”，为什么要提取中面，如何提取？
      3，shell单元法线方向需要设置什么？为什么要设置？
俺的问题可能是多了一点，有做过这方面研究的高手，还请您指教一二，本人不胜感激！！！

You can get examples from the LSDYNA panel in simwe, there are a lot of eamples by the the friends in this panel. so find it by your self.
In essence, you donot need to compile your own model, download one from this site and can change the download sample to your own sample to solve your own problem.
