| Research Abstract |
The purpose of this study is to develop a numerical method which is able to accurately simulate large amplitude ship motion in rough seas and impact force acting on ship’s hull using a particle method. To accomplish this purpose, a new ship motion model and an open boundary condition were developed using a particle method. Moreover, a zooming technique was developed for a particle method to simulate fluid behavior around ship in high spatial resolution at low computational cost.
