请问：这个问题中，Fluid-structure interaction BCD 2 and 1 are connected，怎么解决？FSI边界条件分成1、2、3、4是为了和结构部分对应。
Connected fluid-fluid interface BCD 6 and 5 are not allowed这个错误又要怎样才能解决呢？
请高手指点！

回复 1# 的帖子

网格问题很大~~

yumingkun 发表于 2008-3-6 21:32:49

回复 3# 的帖子

这个是网格问题是还是边界条件问题呢？提示得失边界条件相连啊～～～
针对这个问题，版主觉得怎么样改进可以做出来呢 ？
