a C++/F90 low Mach number stellar hydrodynamics code
Maestro solves the equations of low Mach number hydrodynamics for stratified atmospheres/stars with a general equation of state. It includes reactions and thermal diffusion and can be used on anything from a single core to 100,000s of processor cores with MPI + OpenMP.
A description of the algorithm and links to the algorithm papers can be found here:
