| Popis: | preprint post-review; International audience; This paper shows the use of the Lattice Boltzmann Method for the simulation of the diffusion equation in heterogeneous media. The theoretical background of the method for both homogeneous and heterogeneous media is developed. A simple method of determination of the conditions of safe use of the LBM is proposed, accompanied by a practical example. The range of interest and condition of non-negativity of the equilibrium distributions are determined for a broad range of diffusive properties ratios. |
