transient acoustic source simulation help

Dear All,

I try to simulate a transient motion of one solid cylinder in the water as my acoustic source.
I use ALE (Moving Mesh) to have the displacement of the cylinder.
Here is my question. I want to use this movement as my transient acoustic source.
Pressure = Displacement*(some other parameters).
I set this pressure as one of the boundary source in acoustic module.
I try to call the results from my solution1(ale.dxz- surface displacement), but it looks to me I can not get anything.
I tried to use the parametric sweep and stationary study, but my pressure is always zero...
Is this the coupling issue?

Any suggestions and considerations is appreciated.

Thanks
Xu
