The gas distribution is shown for a from a cosmological formation simulation using the codes GADGET (bottom) and AREPO (top). The nested views show the similar large scale structure (left panel), but also reveal very different gas distributions around galaxies (right panel).

The Kelvin-Helmholtz instability is simulated using Gadget (left) and Arepo (right). The resolution in both cases is 240x240, with Gadget using N_ngb = 16.
