I am trying to simulate a closing of ball valve which would require sliding mesh setup. I would like the flow to start from t = 0 until certain time (eg t = 5 s) then the valve will start to rotate (maybe in 4 seconds) then stop rotating and the simulation will still continue up to another 5 - 10 seconds. It will be something like this:
0 < t < 5, rad/s = 0;
5<= t <= 9, rad/s = 0.5
t > 9, rad/s = 0
Hope to get some advise here :).

You'd set the motion in the cell zone panel. I'd start here https://ansyshelp.ansys.com/account/Secured?returnurl=/Views/Secured/corp/v231/en/flu_ug/flu_ug_expressions.html for the syntax.
