INTRODUCING THE LABORATORY FOR COMPUTATIONAL ASTROPHYSICS The LCA is a joint venture between the NSF, the National Center for Supercomputing Applications, and the Department of Astronomy at the University of Illinois, Urbana-Champaign. Its purpose is to develop and disseminate numerical algorithms and community codes for CFD, primarily for astrophysics. The LCA currently provides the following packages: * ZEUS-2D: a one- or two-dimensional (moving) Eulerian grid code for radiation magnetohydrodynamics. * ZEUS-3D: a one-, two- or three-dimensional explicit (moving) Eulerian grid code for magnetohydrodynamics. * TITAN: a one-dimensional implicit adaptive mesh code for radiation hydrodynamics. * 4D2: an interactive tool for visualizing and animating 3D data (array, particle) on Silicon Graphics workstations. The community application codes (ZEUS-2D, ZEUS-3D, TITAN) are available to academic researchers via a royalty-free license agreement. Some LCA tools (4D2) are in the public domain and available via anonymous ftp.
