Moving wall and slip velocity

I’m trying to do a manual coupling between fluid and structure (using PDE).
I have got the fluid loading on the structure by applying the fluid total stress (pressure and viscous stress) as a load on the structure. [ no problem with one way coupling]
[Coupling the structure effect on the fluid]
To achieve this coupling, I used the slip velocity BC (with no slipping, [u_wall (x,y)= u2t and v2t] which are the time derivatives of the structure displacements) to simulate the velocity transmission to the fluid.
This worked fine for me, but I want to know why is not working when I use the moving wall BC because I want to use this boundary to couple the interior wall.
I would be very pleasant and appreciated if anyone can explain or help me with this issue.
My best wishes,
Yousef
