a 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:

To use Maestro you need a copy of the BoxLib library, available on github at:

https://github.com/BoxLib-Codes/BoxLib.git

A Getting Started guide is provided in the Maestro User's Guide. To build the User's Guide, cd into Docs/, and type make, or download the PDF here:

New features are committed to the development branch. Nightly regression testing is used to ensure that no answers change (or if they do, that the changes were expected). No changes should ever be pushed directly into master.

On the first workday of each month, we perform a merge of development into master, in coordination with BoxLib, Castro, and Microphysics. For this merge to take place, we need to be passing the regression tests. To accommodate this need, we close the merge window into development a few days before the merge day. While the merge window is closed, only bug fixes should be pushed into development. Once the merge from development -> master is done, the merge window reopens.
