Abstract
The basic physical equations as well as a computer code for the simulation of one-dimensional radiation hydrodynamics are described. The hydrodynamic equations are combined with a multigroup method for the radiation transport. The code, written in standard FORTRAN-77, is characterized by one-dimensional planar geometry with multilayer structure. A time-splitting schema has been adopted with implicit finite-differencing formulation (including the hydrodynamics), and Lagrangian coordinates. Tabulated equations of state and opacities are used.
