(a) Schematic representation of cells within a tissue organized in a periodic lattice, based on the assumption that cells are dilute, noninteracting, and spherical in shape. (b) Finite-element mesh showing boundary conditions and three symmetry planes. In the multiscale formulation, each Gauss point in every element is associated with a unique representative volume element (RVE) comprised of a random, interconnected network.
