内容記述 | Modeling ocean wave propagation using particle method faces difficulty due to its high computational cost, especially when it is computed in large domains. By coupling a cheap model in the large deep sea region and a precise model near the shoreline, we can reduce this difficulty. There had been already proposed models coupling Navier-Stokes equations with a Boussinesq model. Herein we propose to couple a finite difference Shallow Water Equation (SWE) model for the deep sea with a Smoothed Particle Hydrodynamics Navier-Stokes Equation (NSE) model close to the shoreline where the waves break and overturn. The cheap SWE model represents the large com-putational domain whereas the NSE model is necessary to deal with the complex behavior of the free-surface at the shoreline. We present results of simulations of water waves for a flat bottom and an inclined bottom as a representation of coastal area. | |||||
