A Progressive Mesh Method for Physical Simulations Using Lattice Boltzmann Method on Single-Node Multi-GPU

摘要

In this paper, a new progressive mesh algorithm is introduced in order to perform fast physical simulationsby the use of a lattice Boltzmann method (LBM) on a single-node multi-GPU architecture. This algorithm isable to mesh automatically the simulation domain according to the propagation of fluids. This method canalso be useful in order to perform several types of physical simulations. In this paper, we associate thisalgorithm with a multiphase and multicomponent lattice Boltzmann model (MPMC–LBM) because it isable to perform various types of simulations on complex geometries. The use of this algorithm combinedwith the massive parallelism of GPUs[5] allows to obtain very good performance in comparison with thestaticmesh method used in literature. Several simulations are shown in order to evaluate the algorithm.
