Diffusional transport through an array of fixed obstacles. The 2D periodic simulation box is bounded in the third dimension by two reservoirs with fixed densities ρ = ρ0 and ρ = 0 between which a stationary diffusion current develops. This current depends on the number and size of the fixed spherical obstacles (grey) and on their interaction with the small mobile particles (red). For more details see text.
