摘要：

We formulate an extension of the lattice Boltzmann equation to irregular lattices. It is demonstrated that the recovery of isothermal Navier-Stokes equations is possible by a construction of the local equilibrium subject to an extended list of moment constraints which take into account the lattice geometry. A particular version of the local equilibrium is discussed in some detail.
