Free-Surface Ship Flow - Boundary Conditions
 

I've been using CFX-10 to model the free-surface flow around a ship hull form and just wanted to check which are the best boundary conditions to use on the port and starboard far-field boundaries? Will the use of walls or symmetry planes cause reflected waves if they are not placed far enough away from the hull and hence encroach on the Kelvin wave system? Would some kind of outlet or non-reflecting boundary condition be better suited?

Ship On Free Surface
 

I am Sony, from Indonesia

now i am doing my MAster thesis project by using CFD ansys 13 version. i intend to generate free surface simulation to predict ship resistance. the boundary condition in tutorial in term "free surface over bump" does not show good result. the simulation is always not finish. any body can help for explaining boundary condition used in free surface ship simulation in CFX? and may be also showing physical model that can be adopt?

Thank you
