Momentum transfer of a Boltzmann-lattice flluid with boundaries Phys. Fluids 13, 3452-3459

The Bouzidi boundary condition is a common choice for curved or off-lattice boundaries. It is a variant of the half-way bounce-back scheme, with extension from no-slip to a general Dirichlet boundary by addition of momentum, and an adaptation of the exact boundary location by use of interpolations.
