Hi guys,

I want to add kind of disturbance to my simulation.

At Timestep1: My Velocity is defined as (1 0 0)
AT Timestep 10: It should be (1+amplitude*sin(2*pi*t))
until Timestep 20

And then it should return to (1 0 0).

How can i implement this kind of time depending Boundary Condition?

Thanks for help

I did something similar a time ago. The easiest way is to use swak4foam, it is quite straightforward.
