Development of a Coupled Method of Finite Volume and Particle Methods Based on Peer-to-Peer File Exchange

To assess the survivability of damaged ships, a numerical method is developed to simulate the motion of a floating body with partially filled tanks. The present method couples the moving particle simulation (MPS) with the finite volume method (FVM) by using peer-to-peer file exchange to retain the advantages of each discretization technique. In this study, the motion of a floating body with partially filled tanks in incident regular waves is analyzed. The MPS is applied for the water in the tanks, and the FVM is applied for the floating body interaction with the waves. Calculated results show good agreement with the data measured, and the relationship between the hydrodynamic forces exerted by the water in the tanks and the wave is revealed.
