Dear Elmer
The problem of injection of a fluid from a piston to a cavity is quite routine as used in the tutorial "Blood ejection from a ventricle into aorta" . Now I want to ask about the inverse problem, i.e, the suction of the fluid from a cavity to a piston as a result of piston's opposite end displacement. Is it possible to solve such a problem by Elmer?

Re: Modeling suction process of a piston
Hi Hamed
There is no reason why. If you do not want to code a model for the piston yourself, you could perhaps use a effectively 1D elasticity equation for the piston and do normal FSI computation. In this case you would need some artificial compressiblity to mimic the piston in order to make the internal flow simulation for the N-S more easy to solve.
