Two ways to get it right:
1) For velocity conditions (for ideal incompressible flow), the ANALYTIC velocity profile can be obtained, and that should be used at the entrance.
2) For pressure conditions (for compressible flow), please see the following paper:
F. Verhaeghe, L.-S. Luo, and B. Blanpain.
Lattice Boltzmann modeling of microchannel flow in slip flow regime.
