应用OpenGL动态模拟波浪对结构物的绕射

应用高阶边界元法计算了波浪对任意三维结构物的绕射。通过选取合适的格林函数,避免了在广阔海域中积分,仅需要在物体表面积分。此外,应用OpenGL技术在计算机上动态显示波浪的绕射过程。显示程序可以调节视角、显示模式、背景颜色和光照等参数。最后,应用文中程序计算了波浪对单个圆柱、单个方箱以及工程实例中的Snorre平台的绕射,通过对计算结果的动态显示,直观地显示了波浪与结构物作用的结果。

Animation of wave diffraction from structure by OpenGL

Diffraction of waves from three-dimensional arbitrary structures are calculated by applying a high-order boundary element method in this paper.The integral in the whole sea area is avoided by choosing the proper Green function.Only the integral on the body surface is needed.In addition,the process of wave diffraction is displayed dynamically on the computer with OpenGL technology.The display program can adjust the angle of view,display mode,background color and illumination,etc.Finally,the diffraction of waves from a single column,a single box and Snorre platform with the program presented are calculated in this paper,and the wave diffraction from structures dynamically is directly displayed.
