On the Definition of a Computational Fluid Dynamic Solver using Cellular Discrete-Event Simulation

Journal of Computational Science
2014

Abstract

The Discrete Event System Specification (DEVS) has rarely been applied to the physics of motion. To explore the formalism’s potential contribution to these applications, we need to investigate the definition of moving gases, liquids, rigid bodies, and deformable solids. Here, we show how to use Cell-DEVS to analyze the movement and interactions of fluids using computational fluid dynamics (CFD). We describe a set of rules that produce the same patterns as traditional CFD implementations. We present the inner workings of the CFD algorithm, the incorporation of solid barriers, and the adoption of variable time steps within the context of biomechanical simulations.

Systems Design & Simulation

While traditional programming practices have produced a wide range of relatively independent simulation methods, predictive models of extremely complex natural and artificial systems will require a more scalable, more collaborative approach to modeling. This project strives for software that will help researchers develop, debug, document, share, and integrate simulation code.
