Hey all,

I remember that we fixed the issue with the missing 0.5*h*F some years
ago. For a flat bounce-back wall aligned with the lattice axis, the
actual hydrodynamic no-slip wall is positioned in the middle between the
last fluid node and the first wall node.

There is still a viscosity dependent slip velocity, cf. Eq. (20) in [He et al. (1997), J. Stat. Phys. 87, 115].

Cheers,
Ulf
