【摘要】 基于物理过程的建模方式能够真实地模拟流体的运动状态,表现出很好的模拟效果,但对不同的流体形态以及同一种流体的不同细节状况,所涉及到的细节属性参数也不同,通常存在着较大的建模差异。首先对流体动力学的流体模拟原理进行了分析,在此基础上对水体倒入4种不同形状容器的流体动力学平滑粒子模型进行了研究,提出一种基于分块的邻居粒子搜索方法,以提高在空间均匀网格上对邻居粒子的搜索速度,给出了流体与器皿碰撞的判断与响应方法。最后通过水体注入不同器皿的仿真试验验证了所建立模型的有效性。更多还原

【Abstract】 Modeling approach based on physical processes can simulate the real state of fluid movement,obtain good simulation results.However,different forms of fluid and same fluid of different details,involved in the different details of the property parameters usually have large differences in modeling.This article first analyzed the principle of dyna-mics fluid simulation,and then based on smoothed particle hydrodynamics model,studied four different shapes water poured into containers,proposed a neighborhood particle search method based on the blocks to improve the neighborhood particle search speed on uniform grid space,gave fluids and containers collision response determine methods.Finally,the simulation tests of water into the different containers verify the effectiveness of the established model.更多还原
