Abstract: Smoothed particle hydrodynamics (SPH）is a non-grid fluid simulation method, while the simulation of solid-liquid interaction problem is a great challenge in SPH. This paper proposes an intensive single layer particles method which garding the boundary as the solid particles and assuming that these solid particles have a certain density, and it is different from the traditional virtual particle method which simply put the boundary as the stationary fluid particles. This method can significantly reduce the number of fluid particles cross the solid boundary during the simulation.
