Abstract: 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.

Key words: fluid simulation, smoothed particle hydrodynamics, boundary correction
