  • Description: In the previous works, the authors have developed a mixed MPS (Moving Particle Semi-implicit) method -- modal superposition model for the highly non-linear hydroelasticity computation [1]. For the structure dynamic part, the rigid and flexible modes are coupled and their mutual effects are considered. The resultant governing equations for the structure part are highly non-linear. In order to further improve the time integration accuracy, the governing equations were first reformulated into ordinary differential equation systems, then the Precise Integration Method (PIM)[2, 3] was used to solve these equations. The dynamics of flexible wedge was simulated by the developed numerical scheme, which showed a better accuracy for long time simulation compared with normal schemes such as Newmark method.
