摘　　要：提出了一种基于物理的流体运动模拟方法,同传统的模拟技术相比,基于物理的模拟更能表现真实感运动。选用的物理模型是完整的Navier-Stokes方程组,针对完整的Navier-Stokes方程组,利用破开算子法将模型分解成外力、对流、扩散和投影项分别进行计算。因为每一步都稳定,所以整个求解过程也稳定。因此可以用大时间步长来模拟流体运动。Navier-Stokes方程组保证了真实感,而此求解方法保证了效率。A physically based algorithm for fluid movement simulation was proposed. Compared with the traditional simulation technique, physically based simulation can represent realistic movement better. The full Navier-Stokes equa- tions are used 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 in the fluid movement simulation.
