...-DOF model to analysis the motion of the ship, the single phase level set method was applied to capture free surface flow around ship, the overset grid technique to simplify the rudder angle and ship rotating motion under the force of the rudder and a prescribed body-force propeller model is adopted...

.... The simulation is achieved by the method which involves higher-order upwind scheme, a blended k– ω / k–? two-equation turbulence model, free surface tracking approach, structured overset grid and 6 degrees of freedom motion method. The resulting roll period is 1.74% shorter than the experimental data...

... is an in-house developed code. RANS equations are solved by finite difference method and PISO arithmetic. Level-set method is used to simulate the free surface. Computations were performed for the standard DARPA SUBOFF model. The structured dynamic overset grid is applied to the numerical simulation of submarine...
