1) How can I change the velocities at every time step. Say x1 m/s for 0.02s, x2 for 0.04s etc?

2) does fluent have an option of angular velocity input?

Urgent help please...Thanks a lot!

Providing you all with some more details to understand the problem.
The model is a closed domain. There is no inlet or outlet. I am just providing the initial velocities. I wana change this velocity at every time step say x1 for 0.02s and x2 for 0.04s etc
