In the paper, ways for defining the boundary conditions of the multiparticle lattice-gas FHP-MP model are discussed. Particular attention is paid to the unsteady boundary conditions. A method for moving walls in the model is suggested. It allows using obstacles which are walking while the simulation is run. Computer experiments with a piston movement in the cylinder were carried out. They showed that the simulated process corresponds qualitatively to the physical laws.
