Interactive 3D Fluid Simulation: Steering the Simulation in Progress Using Lattice Boltzmann Method

Abstract

This paper describes a work in progress about software and hardware architecture to steer and control an ongoing fluid simulation in a context of a serious game application. We propose to use the Lattice Boltzmann Method as the simulation approach considering that it can provide fully parallel algorithms to reach interactive time and because it's easier to change parameters while the simulation is in progress remaining physically relevant than more classical simulation approaches. We describe which parameters we can modify and how we solve technical issues of interactive steering and we finally show an application of our interactive fluid simulation approach of water dam phenomena.

Interactive simulation for easy decision-making in fluid dynamics

“…To be able to integrate any simulation tools daily used by experts, and to ensure the quality of the simulation results, we have developed an API called CFDriver [13] embedding a network protocol to perform the data communication between the simulation tool and visualization one. As a cross-platform API, it works with different programming languages and on different operating systems.…”
