I am trying to simulate something which is like a double acting reciprocating cylinder. in this case if the pressurised fluid is admitted into the cylinder using inlet valve, the impact due to the pressure on the disc/piston inside the cylinder should be able to move inside the cylinder.
Is It possible with this software??
You can use Sim CFD to analyse flow driven motion, which is your solid piston being moved by the working fluid, though it will require some extra input if you have friction and opposing forces.
