Please guide in this problem. I will be greatful to all of you if you will tell me the correct way to simulate this problem. Thanks in advance.

In gambit you define a geometry - is wise to work with structured mesh in this case. You are going to have some problems defining the boundary conditions. I recomend you the velocity inlet and pressure outlet. The initial water level can be patched to your geometry in fluent (chech the vof tutorial). The biggest problem your going to face is wave reflection at boundaries - the easiest way to avoid this is by makng a mesh really big so the wave amplitude is damped when it reaches the boundary. Also check the previous messages on the forum - im shure youll find something hope i helped regards MATEUS
