The observed Cosmic Microwave Background radiation tells us that the Universe was almost homogeneous some 13.8 billion years ago. At present, we observe structures on all scales from the tiny dwarf galaxies with masses below 10^8 solar masses up to the most massive structures in the universe, the super-clusters with masses around 10^16 solar masses. All these structures have been formed from small density fluctuations at the beginning of cosmic history. One of the most demanding challenges for cosmologists is to understand how observed structures form across eight orders of magnitude of scale.Within the CosmoSim database project (www.cosmosim.org) we have performed a series of simulations with 3840^3 or 4096^3 particles in boxes of 4000 Mpc/h, 2500Mpc/h, 1000 Mpc/h and 400 Mpc/h. Now we intend to extend the CosmoSim database with two new simulation boxes of smaller size, 160 Mpc/h and 64 Mpc/h, to study strucutre formation on very small scales. As for the previous simulations all halo catalogues will be made available at the CosmoSim database.
