A simulation snapshot from He, Ricotti & Geen, 2019 that demonstrates the Adaptive Mesh Refinement technique of the RAMSES code. A large part of my research relies on running supercomputer simulations using RAMSES-RT, a radiation-magneto-hydrodynamic code for general purpose simulations of self-gravitating fluid dynamics. RAMSES-RT is one of few radiation-MHD codes available that is suitable for star formation simulations. The utilization of the Adaptive Mesh Refinement strategy enables the grid-based hydro solver to deal with extremely high dynamic range.
