Simulate a ship in free surface area
 

Hi, I am student from Indonesia. Now, I am doing a research about CFD Investigation of Resistance of Pentamaran Hull Ship. In this research I am using Ansys Fluent to simulate the multiphase flow in free surface region. I am trying to divide the region, but the result doesnt show the correct region. Please give me advice in define the boundary and patching the region.
inlet as velocity inlet, outlet as pressure outlet, wall as wall and ship as statical body.
