How to model the static pressure buid-up in FSI
 
Hi

I modeled a solid hollow cube which is filled with water, but the steady state average of the fluid pressure is almost zero when the structure deforms.
Is there any option in CFX to model pressure change when the volume of a fluid-filled cavity changes?
I used Ansys/CFX and a two-way FSI approach. the structure deforms significantly in response to the imposed load without any error. the Fuid does also perfectly follow the structure boundary.

I would really appreciate if somebody can help me.
