an adaptive mesh, astrophysical radiation hydrodynamics simulation code

Castro is an adaptive-mesh compressible radiation hydrodynamics code for astrophysical flows. Castro supports a general equation of state, full Poisson gravity, and reactive flows, and is parallelized with MPI + OpenMP.

More information on Castro can be found here:

To build Castro, you need a copy of the BoxLib library:

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

There is a User's Guide in Castro/Docs/ (type make to build from LaTeX source) that will guide you through running your first problem. A PDF of the User's Guide can be found at

A doxygen-generated call graph for Castro is available 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, Maestro, 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.
