Ramses is an open source code to model astrophysical systems. It describes self-gravitating, magnetised, compressible, radiative fluid flows with Adaptive Mesh Refinement (AMR), and has been widely used for cosmological simulations of the Universe, isolated as well as cosmological resimulations of individual galaxies, simulations of molecular clouds, star formation, supernovae remnants, accretion disks around black holes and planets. Ramses was written by Romain Teyssier, and is now used and developed by a growing community of astrophysicists all around the world, with many groups in France, United Kingdom, Danemark, South Korea and the United States.
The goal of this website is to promote the activities of the Ramses community in France and internationally. It is edited by the RAMSES SNO (see this page for more details about this structure).

The Obelisk project is a radiation-hydrodynamical cosmological simulation following the assembly of a proto-cluster and its environment until z≃3 aiming to study the first 3 Gyr of evolution of the Universe, before the peak of cosmic star formation. Obelisk relies on state-of-the-art models to describe the physical processes necessary to simulate galaxies and their environment…
