Dynamic Particle Coupling for GPU-based Fluid Simulations

The main research approaches in computational fluid dynamics (CFD) are grid-based or particle-based. For interactive fluid simulations, grid-based techniques for the use of Graphics Processing Units (GPUs) have been developed in order to speed up the simulation.

This paper describes an approach for setting up a particle-based fluid simulation on the GPU. This builds upon earlier results on simulation of uncoupled particles. The major contribution of this work is a new approach for modeling dynamic particle coupling solely based on individual particle contributions. This technique does not need global sorting or an explicite solution of the n-nearest neighbor problem.
