英文摘要：

Lattice Boltzmann Method is a relatively new method in computational fluid dynamics. It possesses some intrinsic advantages over traditional methods, for example, inherent capability for parallel computing and great convenience in treating complex boundaries. With the increase of the importance for supercomputing, lattice Boltzmatm method will play a more and more important role. The calculation model has been relatively mature. Considering the effect of complex geometric boundary, a large number of scholars put forward various boundary treatment in lattice Boltzmarm method. The influence of boundary treatment for computing mainly lies in three aspects： accuracy, stability and parallelism. In this paper, we will give a brief review for the recent progress of lattice Boltzmann method for treating complex boundary conditions. We make a comparison about the advantages and disadvantages of other kinds of boundary treatments, through some calculations of some typical examples.
