Challenging structural-flow model

In theory the steps of this simulation are fairly simple, I suspect an experienced user could spot and fix the problems. I attatched my .mph file, and would love counsel.
I am trying to study the effect a structure has on water flow in a two step stationary study:Step 1:a soft mechanical structure (6 beams) deforms when pressed against a hard surface.Step 2:laminar flow above the surface- being affected by the deformed structure.
At the moment step 1 is successful, but the flow analysis in step 2 is solving forthe initial mesh(before the structure deforms, i.e before step 1). I set the initial condition for step 2 to begin at the end of step 1, but haven't had success. Also I attempted to use a moving mesh, but had no success either. For the file size I removed the mesh, but used a physics-controlled 'Normal' mesh so far.
Help would be much appreciated!
note: I added an auxiliary sweep to help the stationary computation of the soft structure's deformation. This is a simplified structure, later I will add a structure with many more beams.

mapped mesh will be helpful in this issue i think so , not sure about it because cant able to open the file . i am using 5.4 .
