Thanks Rob, 

Where do I define the free surface ? My domain is a square box of height 100m. I want my watersurface at 50m. I have placed my body at an intial roll displacement of 5 degrees. Since I am not using open channel flow or waves, in which boundary condition can I set the water free surface?
