中文摘要：

基于粘流理论、流固耦合理论和自由液面追踪技术———VOF（Volume of Fluid）法，以不可压缩流体的连续方程和N－S方程及结构动力学方程为基本控制方程，利用商用软件ANSYS Workbench 的二次开发功能，建立了粘性数值波浪水池，数值模拟了完全非线性波的生成，计算分析了二维浮式结构物遭遇波浪的完全非线性现象，得到了甲板上浪水位高度和结构物的纵摇、垂荡、横摇等运动响应。结果表明：文中的方法可以用于波浪与浮式结构物相互作用的完全非线性数值模拟。

英文摘要：

Taking continuity equation of incompressible fluid , N-S equation and structural dynamics equation as the governing equations and using fully nonlinear free surface conditions and structural boundary conditions , we establish the viscous numerical wave tank based on viscous flow theory , fluid-solid coupling theory and free surface tracking technique -VOF （Volume of Fluid） method.Wave running up along the bow , wave deforming and wave breaking are recorded in these simulations .The wave height on deck and motion response such as pitch, heave and sway are obtained .The results indicate that the present numerical scheme and method can be used to simulate the fully nonlinear wave interaction with the floating structures .
