Hi CFDians,
I have doubt regarding boundary conditions used in Star CCM+ for wave and forward speed simulations. Which boundary condition has to be used for Side walls,Top and bottom boundaries..? A velocity inlet or a slip wall..? and why..?
Of course in tutorials, they have used velocity inlets...

Hi, Dronzer.
You can follow the numerical wave tank part in the tutorial of Marine resistance prediction: KCS Hull with Rudder.
Side: symmetry, top: velocity inlet; bottom: wall.

The reference you said to follow
I am following this tutorial and in the tutorial the BC are-
Inlet,Top,Bottom=inlet
outlet=pressure outlet
side,symmetry=symmetry plane.

My Question is how tank top can be inlet?
any physical explanation?
