Typical fluid-structure interaction model

Hi
I am new and struggling to start a simple model.
I have been playing with blood vessel model from the model library.
I would like to look at the vascular behavior when blood vessel is impacted by a piston.
It is going to be dynamic analysis and I want control the velocity of piston and depth of impact.
My question is that how I can make piston move with certain velocity and control the displacement of piston.
And also how can I solve the problem with dynamic analysis?
Any help will be appreciated.
Thanks

Hi
but arent velocity and displacement linked ?
for me s=s0+v0*t where s0 is the initial position and v0 the (assumed here constant) velocity
so try to define an imposed displacement as
s0[m]+v0[m/s]*t
with i.e s0 and v0 defined as parameters

Good luck

The piston moves 1mm of displacement with 7m/s of velocity.
