一个一维对流扩散问题的数值计算 ，对流项采用UDS或CDS差分格式，扩散项采用CDS差分格式-This program solves the one-dimensional convection-diffusion equation with Dirichlet boundary conditionson both ends. The exact solution is compared with solutions obtained using FD method and either U

运用LBM解得一个浓度方程的小程序，非常有用！解对流扩散方程，可以直接带入自己的！-Use LBM of or concentration of a small program, very useful!Convection diffusion equation, the solution can be directly into your own!
