方腔流动的lbm代码，模型是D2Q9.本人自己写的-Cavity flow of lbm code

对初学者LBM有一定的帮助，这是方腔流动的模拟，采用的D2Q9模型，效果很好。-which will have help for the freshman of LBM,this is the simulation of cavity lid driven flow,apply the D2Q9 model

用LBM模拟方腔流，C++语言，运用曲线边界条件。-LBM simulation with cavity flow, the use of curve boundary conditions.
