Directory Breakdown

The AstroBEAR source code is organized into several subdirectories that each contain modules designed to handle a particular aspect of the code.

What is in each directory

• tree - Contains modules that define the AMR tree structures as well as various routines for manipulating the AMR tree.
• data - Contains modules that define the data structures associated with each grid or patch as well as operations for synchronizing the data, and for performing operations on the data.
• particle - Contains modules that define the data structures associated with Lagrangian particles, and routines for performing operations on particles.
• amr - Contains control routines for advancing the AMR dataset in time.
• distribution - Contains routines for distributing workloads over multiple processors.
• communication - Contains routines for performing communication needed to synchronize data across processors.
• hyperbolic - Contains routines for performing conservative hyperbolic advances.
• elliptic - Contains routines for solving linear systems of equations such as poisson's equation used by the self-gravity module.
• explicit - Contains routines for solving parabolic equations through explicit sub-cycling
• physics - Contains definitions and functions related to the particular equations being solved.
• io - Contains routines for writing and reading simulation data to disk.
• modules - Contains various routines for controlling initial and boundary conditions
• source - Contains various routines for applying source terms.
• processing - Contains routines for analyzing the data and producing various data products.
• layouts - Contains modules for mapping AMR datasets onto uniform subgrids.
• threads - Contains modules for handling threading of level advances.
