Welcome to AMReX’s documentation¶
AMReX is a software framework containing all the functionality to write massively parallel, block-structured adaptive mesh refinement (AMR) applications. AMReX is freely available on Github.
AMReX is developed at LBNL, NREL, and ANL as part of the Block-Structured AMR Co-Design Center in DOE’s Exascale Computing Project.
All of AMReX’s development is done in the github repository under the development branch; anyone can see the latest updates. A monthly release is tagged at the beginning of each month.
We are always happy to have users contribute to the AMReX source code. To contribute, issue a pull request against the development branch (details here). Any level of changes are welcomed: documentation, bug fixes, new test problems, new solvers, etc. To obtain help, simply post a discussion or an issue on the AMReX GitHub webpage.
There are small stand-alone example codes that demonstrate how to use different parts of the AMReX functionality; there is extensive documentation for these tutorial codes at AMReX Tutorials
Besides this documentation, there is API documentation generated by Doxygen.
Documentation on migration from BoxLib is available in the AMReX repository at Docs/Migration.
