摘要

Abstract

Submarine landslide is a complex geological phenomenon. Simulating sliding body flowing along slope more realistically has been a popular research focus in recent years. In this paper we present a PCISPH numerical simulation model to simulate submarine landslide like fluid

allowing for better incompressible constraints. With respect to fluid-solid interaction between particles and complex boundaries

we integrate speculative contacts method to solve jittering effect. We use classical marching cubes algorithm to render discrete particles into high-quality consecutive surface meshes. All aspects of our implementation are entirely paralleled on the GPU by using CUDA. The experiment results show our method can simulate landslide process vividly with high-efficiency.
