Viscous CFD simulation for ships with large amplitude motions by dynamic overset grid method

研究船舶在波浪中的运动是船舶水动力学研究的重要内容之一，是实现水面船舶在真实的海况下安全航行的基础。计算流体动力学（CFD）软件已经开发，以解决不可压缩的粘性绕流船舶在波浪中运动。通过二维和三维物体非定常运动的计算结果与实验/参考数据之间的比较，证实了该代码的有效性。

Investigation of ship motions in waves would be one of the crucial issues in ship-hydrodynamics to achieve safety transportation of surface vessels in real sea state. Computational Fluid Dynamics(CFD) software has been developed in order to solve incompressible viscous flow around ships moving in waves. The validity of the code has been confirmed throughout comparisons between computational results and experimental/reference data of unsteady motions of 2D and 3D objects.
