Hi,

How do I set time dependent translation velocity on my fluid region. For example, I need to set [0,0,1] m/s for first 0.01s then [0,0,-1] for the next 0.01s and so on periodically. Anyone have any idea?

Thank you.

Set your velocity definition to components and make a field function that's a sine wave with the appropriate properties based on the velocity function you want to use. Then apply that field function as the definition of the component in the z direction.
