Physically Based Simulation of Fluid Movement

A physically based algorithm for fluid movement simulation is proposed. Compared with the traditional simulation technique, physically based simulation can represent realistic movement better. The Navier-Stokes equations are adopted as the model, and the operator splitting method is employed to split the model into external force term, advection term, diffusion term and projection term. Every step is stable, so the whole process is also stable. Thus, the large timestep can be taken to ensure the simulation speed in the fluid movement simulation.
