Abstract

Based on the Smoothed Particle Hydrodynamics (SPH) and Finite Element Method (FEM) model, we propose a method for realtime simulation of fluid with deformable bodies. The two-way coupling method for the fluid with deformable bodies is processed by the raytraced collision detection method instead of the ghost particles. Using the forward ray-tracing method for both velocity and position, different normal and tangential conditions can be realized even for the cloth-like thin solids. The coupling forces are calculated based on the conservation of momentum and kinetic energy. In order to take full advantage of the computational power in modern GPUs, we implement our method in NVIDIA CUDA and OptiX. The simulation results are analyzed and discussed to show the efficiency of our method.
