本文介绍了九州大学应用力学研究所(RIAM)最近发展起来的两种新的数值计算方法，用于研究强非线性波体相互作用问题，如船舶在波涛汹涌的海浪中的运动以及由此产生的绿水对甲板的冲击。第一种方法是基于CIP的笛卡尔网格法，将自由表面流动处理为多相流，采用笛卡尔网格进行求解。第二种方法是MPS方法，这是一种所谓的质点方法，因此不使用网格。介绍了这些数值方法的特点和计算过程。文中还给出了一个新进行的溃坝试验的验证计算。
In this paper, two novel numerical computation methods are introduced which have been recently developed at Research Institute for Applied Mechanics ( RIAM ), Kyushu University, for strongly nonlinear wave-body interaction problems, such as ship motions in rough seas and resulting green-water impact on deck. The first method is the CIP-based Cartesian grid method, in which the free surface flow is treated as a multi-phase flow which is solved using a Cartesian grid. The second method is the MPS method, which is a so-called particle method and hence no grid is used. The features and calculation procedures of these numerical methods are described. One validation computation against a newly conducted experiment on a dam break problem, which is also described in this paper, is presented.
