Hi, I'm using Ansys CFX for my final year project. I used FSI 2 way coupling method in this simulation and cosine wave forces was used to represent the piezo force.

But there is an error in fluid domain. It says it can not get the total mesh deformation from ansys. Some forum said it might because of the boundary conditions.

Can anyone help me and tell why this is happening?
Sorry for poor language >_<
