Adaptive Mesh Refinement Resources

This page is a partial list of freely available structured adaptive mesh refinement codes, tools and other resources for using adaptive mesh refinement to solve PDEs.

Freely available general-purpose software for patch-based structured AMR

The codes in the list below were chosen because they meet most of the following criteria. For the most part, these codes

AMRClaw R. J. LeVeque (Univ. of Washington, Seattle, WA, USA) and M. Berger (New York University, USA)
BEARClaw S. Mitran (Univ. of North Carolina, Chapel HIll,NC, USA)
AMROC Ralf Deiterding, University of South Hampton (UK)
AMReX Lawrence Berkeley National Laboratory, Berkeley, CA (USA) (formerly BoxLib).
Chombo Applied Numerical Algorithms Group (ANAG), Lawrence Berkeley Laboratory, Berkeley, CA (USA)
PARAMESH NASA/Drexel University, Philadelphia, PA (USA) (For most recent versions of this code, see the FLASH code, below.).
SAMRAI Center for Applied Scientific Computing (CASC), Lawrence Livermore National Laboratory, Livermore, CA (USA).

If you know of a general-purpose AMR package I have left out (especially packages developed outside of the US), please contact me at donnacalhoun [at] boisestate [dot] edu.

The links below are to other codes which also may be of interest to researchers seeking information on structured AMR.

AMR AMR is a package of Fortran routines for the numerical solution of hyperbolic conservation laws in 2 and 3 space dimensions. Developed by Marsha Berger (New York University, USA) (website is likely very out of date).
Pluto A modular code for computational astrophysics. Computations may be carried out in either static or adaptive grids, the latter functionality being provided through Chombo (see above). Developed by Andrea Mignone, University of Torino (Italy).
