BUCKY and ZEUS-2D are two radiation hydrodynamics codes under development at the University of Wisconsin for the simulation of the behavior of high energy density plasmas found in ICF targets and target chambers. The ZEUS-2D code was originally developed at the National Center for Supercomputer Applications. BUCKY is a 1-D Lagrangian code which models many physical phenomena. Verification of these models in BUCKY with experiments is in progress. ZEUS-2D is a 2-D Eulerian radiation magnetohydrodynamics code written for astrophysical applications. It contains relatively simple radiation physics models which are being enhanced by implementing models from the BUCKY code.
