I have a pipe. In the interior region named 'water domain', water is flowing and the annular region named 'pipe' is made up of aluminum. For water, there is an inlet and an outlet from the other end. The outermost surface of 'pipe' is named - 'finally_outerWall'.

If that's the wall next to the solid at the very outside of the domain there's nothing to add momentum too. What are you trying to mimic?

I wanted to give a sinusoidal vibration f(time) = sin(200*t/1[s]) to the external wall at the outermost surface. Trying to compare the flow variables for the vibrating wall and the static wall. Is there any other way?

[Rob]

The vibration won't transmit though the solid zone, you could lose the solid and put the boundary on the wet wall. As it's an adiabatic wall where is the heat going?

Very Initially I was working on an adiabatic case, but now it's not the same and I didn't bother renaming that. And thanks a ton for your help, I'll go check it out. Thank you.
