The lattice Boltzmann method (LBM) is a relatively new method for fluid flow simulations, and is recently gaining popularity due to its simple algorithm and parallel scalability Instead of solving the Navier-Stokes equations, the discrete Boltzmann equation is solved to simulate the flow of a Newtonian fluid with collision models such as Bhatnagar-Gross-Krook (BGK) . Lattice-Boltzmann model The basic theory of the Lattice-Boltzmann method has been described in numerous publications (see e distmesh_3d_test divdif , a MATLAB code which uses divided differences to compute the polynomial interpolant to a given set of data .
