swimming pool water surface motion due to wind

Problem: swimming pool water surface motion simulation

How to model swimming pool is filled with water and above the water surface, there will be a boundary layer type wind.

I'm considering 2D simulation. How can I define one surface with water and the other surface with air as the initial condition?

Use VOF and patch regions appropriately.

Thank you, Jack.

Re: swimming pool water surface motion due to wind

Well, this is a classic Fluid Dynamics Problem - you can do an estimate using hand calculations. Refer to Fluid Dynamics by White.

The solution for the fluid direction vector as a function of depth ends up being a spiral (as seen from the top), if I remember correctly. So if you do a 2D simulation, this will be a shear driver flow only - which I suspect will not give the correct answer.
