couette flow

Hi Dear All,
Can any one have a code about couette flow using LBM.
Such help will be really appreciated. I try to write a code for the problem when the upper boundary is moving with constant velocity and the lower wall is stationary. But i find that my boundary conditions are not work good for such problems. If any one have a code for such problems it will be so nice.
Best wishes and bye for now.
Best Regards

Hello Khan

There is a nice simple MATLAB code where Couette flow is solved using D2Q9i model on the link below.

Hope it helps
