Two cosmological models were simulated in larger boxes (479 Mpc/h for LCDM and 321 Mpc/h for tCDM) than those of the Virgo simulations, while keeping higher mass resolution. We find many clusters in the box, which are still well resolved and thus suitable for re-simulation. The main projects associated with these simulations are:

Shown in the left panels are projected mass distibutions in a sliced region in the simulation box. Low-density regions which look like "voids" are dark, while blue (and light-green) parts are high-density regions. The pictures were created using an adaptive smoothing scheme which assigns to each particle an individual smoothing length. Thus, high density regions are not smoothed at all whereas low density regions are smoothed.
