@@@@Shake of rocker panel was achieved by using of technology of dynamic mesh. Free surface of ship numerical wave tank was simulated through incompressible viscous fluid Navier-Stokes equation and vol-ume of fraction (VOF) method, adding to source term method in the momentum equation in order to wave damping. By using of CFD business software Fluent and its secondary development function, three-dimen-sional numerical wave tank model of regular wave based on physics wave-generating imitating method was established through turbulence model standard k-ε. The result shows that wave generated through physics wave-generating imitating method has the feature of high quality and stability.
