Hello to all, 

I need to model the flow in an FSI valve. I would like to know if it is possible with Ansys to model the evolution of the fluid flow as contact is established. A simplified example of my study is attached

Have a look at the incylinder tutorials/videos in the Help system.n

nI tried to search a little, the tuto you advised me for the similar case I can't find it, can you put me a link please? I have seen other simulations on ? Simulating Fluid-Structure Interaction in a Ball Check Valve ? and they proposed not to represent total contact, to always leave a small gap in contact, do you think it's better to do it that way?n

[Rob]

The gap is to avoid changing topology which isn't recommended. It looks like the old IC tutorial has been superseded, there are the two videos in Help, Fluent:Dynamic Mesh Problem for a Piston and Reed Valve - Part I which should get you going. n
