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 RAMSES SNO is organizing a new user school for the RAMSES code, aimed at PhD students, postdocs, engineers and faculty with an interest in computational astrophysics and numerical simulations.

The Assembling Galaxies Of Resolved Anatomy (AGORA) project, introduced by Kim et al. (2014), aims to compare high-resolution galaxy formation simulations across different high-resolution numerical platforms. The numerical techniques and implementations used in this project include the smoothed particle hydrodynamics codes GADGET and GASOLINE, and the adaptive mesh refinement codes ART, ENZO, and RAMSES.
