an adaptive mesh, astrophysical radiation hydrodynamics simulation code
Castro
is an adaptive-mesh compressible radiation / MHD / hydrodynamics
code for astrophysical flows. Castro
supports a general equation of
state, full Poisson gravity, and reactive flows, and is parallelized
with MPI + OpenMP for CPUs and MPI + CUDA for GPUs.
More information on Castro can be found here:

The "Getting Started" section of the User's Guide walks you through running your first problem:
https://amrex-astro.github.io/Castro/docs/getting_started.html
This will have you clone Castro and its dependencies (AMReX and StarKiller Microphysics),
The User's Guide in written in re-structured text using Sphinx, with
the source in Castro/Docs/
, and is built automatically
via travis from the development
branch.
A doxygen-generated call graph for Castro
is available here:

Development generally follows the following ideas:
-
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).
If a change is critical, we can cherry-pick the commit from
development
tomaster
. -
Contributions are welcomed from anyone in the form of a pull request from your fork of Castro, targeting the
development
branch. (If you mistakenly targetmaster
, we can change it for you.)Please add a line to
CHANGES.md
summarizing your change if it is a bug fix or new feature. Reference the PR or issue as appropriate. Additionally, if your change fixes a bug (or if you find a bug but do not fix it), and there is no current issue describing the bug, please file a separate issue describing the bug, regardless of how significant the bug is. If possible, in both theCHANGES.md
file and the issue, please cite the pull request numbers or git commit hashes where the problem was introduced and fixed, respectively.We will squash commits upon merge to have a clean history. Please ensure that your PR title and and the PR summary field are descriptive, since these will be used for a squashed commit message.
-
On the first workday of each month, we perform a merge of
development
intomaster
, in coordination withAMReX
,Maestro
, andMicrophysics
. 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 intodevelopment
. Once the merge fromdevelopment
->master
is done, the merge window reopens.
People who make a number of substantive contributions will be named "core developers" of Castro. The criteria for becoming a core developer are flexible, but generally involve one of the following:
-
10 non-merge commits to
Castro/Source/
orCastro/sphinx_docs/
or one of the problems that is not your own science problem or -
addition of a new algorithm / module or
-
substantial input into the code design process or testing
Core developers will be recognized in the following ways:
-
invited to the group's slack team
-
listed in the User's Guide and website as a core developer
-
listed in the author list on the Zenodo DOI for the project (as given in the .zenodo.json file)
-
invited to co-author general code papers / proceedings describing Castro, its performance, etc. (Note: science papers will always be left to the science leads to determine authorship).
If a core developer is inactive for 3 years, we may reassess their status as a core developer.
