The AstroBEAR Code

AstroBEAR is an Adaptive Mesh Refinement (AMR) distributed-memory parallel Eulerian code written in FORTRAN 90 which supports hydro- or magnetohydrodynamics in two or three dimensions. AstroBEAR is derived from the ​BEARCLAW AMR package written by Sorin Mitran. Users write their own project modules in AstroBEAR by specifying initial conditions and any continual processes, such as an inflow condition. There exists a variety of modules already built; users are encouraged to use these as a starting point for their own module(s).

Once a module has been written and the executable is ready to be run, users specify simulation parameters—-such as the resolution, how many levels of AMR are desired, source term physics such as radiative cooling, and so forth—-in the data files. The code is most commonly run on Beowulf-type computing clusters, though it has been successfully ported to the BlueGene/P architecture.
