Creating Multiphase waves that do not damp.

Hello all,

I am attempting to generate open-channel waves in the VOF model that will not damp across the domain. I have an velocity inlet with 2 m/s flow velocity. The wave has a length of 6 m and amplitude of 0.5 m.

In past simulations, the first wave is correct, but then begins to damp until completely flat. Does anyone know how to prevent this damping?
Thanks in advance.
