A progressive mesh method for physical simulations using lattice Boltzmann method on single-node multi-gpu architectures

摘要

In this paper, a new progressive mesh algorithm is introduced in order toperform fast physical simulations by the use of a lattice Boltzmann method(LBM) on a single-node multi-GPU architecture. This algorithm is able to meshautomatically the simulation domain according to the propagation of fluids.This method can also be useful in order to perform various types of simulationson complex geometries. The use of this algorithm combined with the massiveparallelism of GPUs allows to obtain very good performance in comparison withthe static mesh method used in literature. Several simulations are shown inorder to evaluate the algorithm.
