RADHOT: A Radiation Hydrodynamics Code for Weapon Effects Calculation.

Abstract

RADHOT is a one - dimensional Lagrangian radiation-hydrodynamics computer code developed from a scheme described by John Zinn of LASL. The transport scheme described by John Zinn and Incorporated into RADHOT requires just two passes thru the mesh to determine fluxes and energy deposition rates. The scheme assumes local thermodynamic equilibrium for each cell, and also assumes that the thermal radiation flux contribution in a given direction at any point has one of two values depending upon whether a ray in that direction intersects the source region. The RADHOT code currently suffers from a lack of valid opacity data. The code as currently written is extremely slow and expensive to run. A user's guide and a listing the code are provided as a starting point for future work. (Author)
