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
