The stochastic generation of microstructures and their characterization were performed with the goal of comparing with experiments. The generated microstructures are composed of three domains, resolved at the micrometer scale: pores, NMC, and CBD. It should be noted that in this model, the pores domain does not account for 100 % of the porosity, since part of it is included in the CBD, but not explicitly described due to its nanometric scale. Periodic boundary conditions were applied along the x and y dimensions, for both generation and characterization.
