摘      要：The coupled level-set and volume of fluid(CLSVOF)method is an advanced interface-capturing method that has been extended to handle overset grid ***,artificial uneven interface may be observed across block boundaries of different sizes and *** present an improved inter-grid VOF interpolation and mass correction scheme to address the *** demonstrate the capability of the improved CLSVOF method,it is applied to the simulation of a container ship in pitch and heave motions under both head sea and following sea irregular wave *** simulation proves that the improved CLSVOF method is capable of revealing detailed physics difficult to see with other *** phenomena simulated in our work include the extensive greenwater propagation on the ship deck,the breakup of overtopping waves into small droplets,and the formation and collapse of air pockets in sudden bow and stern slamming which cause strong and highly localized impacts on the ship bow,stern,and rudder.
