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.
