Request for Shan-Chen based Multi-component code simulating Poiseuille flow with correct boundary conditions

Hy Dear All.

I am very Glad to write on this Page. I am trying to develop Shan-Chen based multi-component code to simulate Poiseuille flow. However, boundary conditions are causing serious problems. I am trying mixture velocity inlet and Neumann Boundary condition at outlet. Does anyone can share the code that can simulate poiseuille flow with correct boundary conditions?
