I want to simulate an unsteady flow with non uniform inlet velocity. The velocity components at a number of points along the inlet boundary is known to vary as a function of time. In short i want interpolation to get the profile and it needs to change with timestep. Is there a way to do it using user defined field functions rather than using a Table (xyz, time). Appreciate some lead..

How can i make it transient?

Thanks for your reply. I did it using the vector field function form
[a-b*$$position[1] + c*sin($Time),d-e*$$position[1] + f*sin($Time + phi),0]
inside velocity inlet components definition
