fluid solid interaction

fluid solid interaction

fluid solid interaction

(OP)
hi,
i'v a truncated thick-walled ellipsoidal model, which is completely filled with fluid such that the solid model totally encloses the fluid. the fluid has no initial velocity, and should have a constant volume.
the solid model will be first be deformed (through applying displacements) at the bottom end(i.e z=constant1) at one instant, and the fluid pressure will rise, thus causing further deformations at the other parts of the solid model. then deformation will be applied at the middle deformed part(i.e z=constant2)(new deformed geometry from last step) of the solid model, and this loop will go on until the last displacement is applied to the top end of the model. The stress/strain at the walls , and the pressure rise of the fluid at each step is desired.

can i use the fsi command in ansys 6.1 to do this, if so which fluid elements should i use
and what are the steps to be taken
or should i use sequential coupling of solid elements and static fluid element (fluid80)

thanks very much
