| Mission |
The mission of the Applied Numerical Algorithms Group (ANAG) is the development of advanced numerical algorithms and software for partial differential equations integrated with the application of the software to problems of independent scientific and engineering interest. The primary focus of our work is in the development of high-resolution and adaptive finite difference methods for partial differential equations in complex geometries, with applications to internal combustion engines and other industrial problems.

Chombo: Adaptive Mesh Refinement Library
The Chombo package provides a set of tools for implementing finite difference methods for the solution of partial differential equations on block-structured adaptively refined rectangular grids. Both elliptic and time-dependent modules are included. Support for parallel platforms and standardized self-describing file formats are included. A reference manual is available online as well. See the Chombo page for details.
STATUS: Chombo version 2.0 released May 7, 2007.
STATUS: Chombo version 1.4 released October 6, 2003.
STATUS: Chombo version 1.2 released April 4, 2002.
STATUS: Chombo version 1.0 released October 12, 2000.
VisIt has superseded ChomboVis as the visualization and analysis tool of choice to Chombo (AMR) HDF5 datasets. ChomboVis is no longer being maintained or developed. Chombo users are strongly encouraged to download, install, and use VisIt. Development of VisIt for Chombo AMR datasets is ongoing and future releases of VisIt should provide addition functionality for Chombo AMR datasets.
The development of VisIt for Chombo datasets is being done by VACET (Visualization and Analytics Center for Enabling Technologies).
STATUS: No longer being maintained or developed (see above).
EBChombo is a collection of C++ classes for the construction of numerical PDE algorithms in complex geometries using the embedded boundary method. EBChombo also includes extensions to BoxLib, a library for the construction of numerical PDE algorithms on rectangular grids, developed by CCSE.
STATUS: EBChombo is in its development phase. The design document for EBChombo is available now, as is a reference manual.
