Acceleration of air flow simulation using lattice Boltzmann method

Onodera, Naoyuki ; Idomura, Yasuhiro

Since diffusion simulations of pollutants attract high social concern, high-precision and real-time analysis is required. We developed a CFD code based on LBM (Lattice Boltzmann Method) with AMR (Adaptive Mesh Refinement). In this presentation, we propose optimum data structure and calculation algorithm for real-time LBM analysis.
