Effect of shape anisotropy on transport in a two-dimensional computational model: numerical simulations showing experimental features observed in biomembranes

We propose a 2-d computational model system comprising a mixture of spheres and the objects of some other shapes, interacting via the Lennard–Jones potential. We propose a reliable and efficient numerical algorithm to obtain void statistics. The void distribution, in turn, determines the selective permeability across the system and bears a remarkable similarity with features reported in certain biological experiments.
