Kelvin-Helmholtz instability

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 Credit: Paul Torrey, Harvard University Center for Astrophysics Institute for Theory and Computation Reference: “Moving Mesh Cosmology: Properties of Gas Disks“ Paul Torrey, Mark Vogelsberger, Debora Sijacki, Volker Springel, Lars Hernquist (2011)
