Can someone please help me with this expression. I am trying to write the below expression in ansys fluent,
v(t) = IF(flow-time < 1,
30,
IF(flow-time < 5.5,
30 + 30 * SIN(PI/2 * (flow-time - 1) / 4.5)^2,
IF(flow-time <= 8,
60,
60)))
2) Also how do I extract the time of the simulation? I am not sure how I can constraint the values I have attached the respective image.

Would really appreciate if someone can help
