Abstract
LBM can conveniently deal with the interaction between fluid and solid. Thus, it is widely used in numerical simulation of multi-physics applications. Based on the domestic processor FT-2000, the numerical simulation of Rayleigh-Bnard convection is carried out. Through performance tests, it is found that the function call overhead of the numerical simulation process occupies nearly of the execution time. By expanding the function call process and reorganizing the data structure, the simulation time for 104 simulation timestep declines from 9236s to 2754s, and the simulation performance of Rayleigh-Bnard convection has improved about .
