ANSYS流固耦合模态分析的问题

bobxia

模型是一块厚0.1mm的半径为6mm的膜（用shell181单元）单元与其下面的厚0.3mm的半径为6mm的水（用fluid30或者fluid220单元）进行耦合

自己根据网上的实例做了一个流固耦合的模态分析例子，但是运行不下去，出现下面的警告，求高手帮忙解答啊！
** WARNING **                         CP =      11.045   TIME= 19:12:21 Both solid model and finite element model boundary conditions have been applied to this model.  As solid loads are transferred to the nodes or elements, they can overwrite directly applied loads.
** WARNING **                         CP =      11.591   TIME= 19:12:23 Coefficient ratio exceeds 1.0e8 - Check results.
