MAESTROeX is part of the AMReX suite of astrophysical hydrodynamics codes that collectively provide the simulation capabilities to model explosive astrophysical phenomena. MAESTROeX specializes in low Mach number stratified flows, such as convection in stars and atmospheres, where nuclear burning can be an important heat source.
MAESTROeX solves the equations of low Mach number hydrodynamics on an adaptive grid, with support for a general equation of state, and nuclear reaction networks. The low Mach number approach allows for large timesteps to efficiently model subsonic flows.learn more
MAESTROeX is built on the AMReX adaptive mesh refinement library, and uses an advance MPI + tiled OpenMP approach to parallelism to get great performance on modern architectures. It scales from 1 to 10,000s of cores, and is run at most national supercomputing facilities.learn more
MAESTROeX (and its predecessor MAESTRO) has been used for scientific explorations of Type Ia supernovae (the Chandra and sub-Chandra scenarios), X-ray bursts, and convection in stellar evolution.learn more
