Depiction of pseudo-RVE and doubly periodic region which was modeled by finite elements. The characteristic dimension of the outer boundary is 1.5 times larger than the pseudo-RVE on which calculations were made for effective conductivity. Periodic boundary conditions were prescribed on the outer boundary.
