Challenges for modern cosmology include determining the influence the small-scale structure has in the universe on its large-scale dynamics and observations. With numerical relativity tools, finding and exploring cosmological models which are exact solutions to the Einstein equations will resolve all the non-linearities so that give us hints on quantifying the influence. In this talk, I will introduce Black-Hole Lattice models, which are subsets of relativistic discrete cosmological models. In particular, I will start from constructing those spacetimes and show what we can learn from exploring their properties.
