二维自适应笛卡尔网格方法及其波浪水池应用
A two-dimensional adaptive Cartesian grid method and its application in a numerical wave tank
摘要
Abstract
To enhance the computational accuracy and efficiency of nonlinear wave simulations,a high-efficiency and low-storage adaptive grid method was developed,and its effectiveness was proven by numerically building a nonlinear time-domain wave tank based on the harmonic polynomial cell method and the volume of fluid method.Subsequently,an adaptive grid method based on a quadtree and a hash table was implemented for automatic,real-time refinement of the free surface.Numerical results demonstrated that the proposed method achieved high grid reconstruction efficiency and linear growth rate in dynamic memory usage.When implemented in the wave tank,it enabled a stable and high-efficiency simulation of both nonlinear regular waves and freak waves.This method is suitable for the numerical simulation of complex waves in ocean engineering applications.关键词
