An analytical method for the generation of model porous structures (lattice structures) exhibiting a given nonuniform void fraction distribution and a given two-point (pore-pore) correlation function is presented, The method proposed for the generation of correlated and nonhomogeneous porous models is based on the application of a nonlinear filter to a stochastic correlated process. This process originates from the linear superposition of a suitable set of stochastic processes possessing Gaussian decay in the second-order correlation function.
