We present results of numerical simulations of the Frisch, Hasslacher, and Pomeau lattice gas model and of some of its variants. Equilibrium distributions and several linear and nonlinear hydrodynamics flows are presented. We show that interesting phenomena can be studied with this class of models, even for lattices of limited sizes.
