Free surface boundary types
I am quite new to openfoam and cfd however I have been trying to simulate two phase flow around a block using interfoam (air and water, block half in half).

I can get the mesh generated and the fluids fields set etc however when I solve my liquid seems to drain out the bottom of the domain even though it is a wall.

Could someone tell me the boundary types that I should be using for inlet, outlet and the walls for files such as alpha, p and u? The idea being that I can visualise the wave pattern and calculate the resistance force on the block before moving onto more complex geometries.

I am using openfoam 1.6

Thanks in advance

Give use some more details on your work.
Are you doing 2D or 3D simulations?
Tell us which boundary conditions you have used so far.
