parthanitr is on a distinguished road
I want to change constant inlet velocity to sinusoidal
(asinwt) velocity which will vary with time. Can anybody send the udf file for the same for which I shall be obliged to you.

vasava will become famous soon enough
Try this one:

DEFINE_PROFILE(unsteady_velocity, thread, position)
face_t f;
begin_f_loop(f, thread)
real t = RP_Get_Real("flow-time");
F_PROFILE(f,thread,position)= 2000.+ 100*t;
