1 hellend112 你定义的结构与流场的单元不匹配，可能是两种网格尺寸差距太大，调剂网格 2010/4/24 02:08
2 hellyeah88g0 首先感谢楼上，我做的过程中，两种网格划分是完整一样的阿 2010/4/24 16:48
3 longbn 可能是耦合盘算时，节点自己运动，偏离FSI接触面，我曾遇到这样的问题 2010/4/25 07:27

5 steven 我已经解决了，在MESHING-CREATEPOINT那里输入流固接触点的点号，在MESHING-ALE MESH CONSTRAINTS-FIX MESH 看你所选中的点是否被固定 这样 在重新画网格就可以了！ 2010/4/26 12:46

7 nxd11g23 因为流体和结构的交互面处的网格不对齐。中间有空隙。处理措施：1.查找空隙的处所，细化网格，或者采用同样的划分方法，避免涌现。2.重新构建此处的流固耦合面。必需要匹配3.如果留空隙，就无法算出结构
