Reply To: Density setting in ADE lattice
That is an LBM discretization of the Boussinesq model euqation https://en.wikipedia.org/wiki/Boussinesq_approximation_(buoyancy). One lattice for mass and momentum and one for the temperature. So it is almost incompressible, gas density (in mass and momentum euqation) -> const. for h->0. You can set the inlet and outlet condition for the mass and momentum equation as in the Navier-Stokes cases and further you have to set another condition for the temperatre in the ADE lattice.
