摘要
使用光滑粒子流体动力学方法进行流体仿真,并提出一种边界校正方法。使用快速泊松盘采样算法对容器边界进行采样,生成边界粒子,对边界粒子质量进行差值估算,计算边界粒子对流体粒子的作用力,以此来仿真流体与边界的相互作用。该方法可避免穿刺、滞留等现象的发生。通过实验验证了该算法的正确性。
This article presents a boundary correction method in fluid simulation based on smoothed particle hydrodynamics. We sample boundaries as boundary particles with fast Poisson disk algorithm, interpolate mass of boundary particles, and calculate force between fluid particles and boundary particles as simulation of fluid-boundary interaction. The presented method can also avoid penetration and holdup. Experiments demonstrated conduct experiments to prove the validity of our method.
