Fluid simulation with rigid body triangle accuracy collision using an heterogeneous GPU/CPU hardware system

Abstract

Fluid simulation is very important for the study of natural phenomena. Most of these phenomena could not be simulated computationally some years ago and for its study the research only had available the manual calculation of its govern equation or a small physical simulation of the phenomena to be studied. With the technology advance, most of these phenomena could be simulate even in real time coming out a new research field called Computational Fluid Dynamic (DFC) only to deal with it. Many researches in DFC use Graphics Processor Unity (GPU) to simulate fluids, forgiving the existence of the CPU, which became idle most time during the simulation. Due the presented fact, we propose a method for using GPU and CPU together during the fluid simulation. Fluid simulation in this work is based on Smoothed Particle Hydrodynamics (SPH), a mesh free Newtonian method for fluid simulation. Also, the rigid body and fluid interaction is dealt at triangle level, archiving more precise results.
