FIREBALL PHENOMENOLOGY AND CODE DEVELOPMENT. VOLUME 4. SPUTTER SUBROUTINES FOR RADIATION TRANSPORT IN PLANES
GENERAL DYNAMICS SAN DIEGO CA GENERAL ATOMIC DIV
The radiation-transport subroutines of the SPUTTER code for plane slab geometry were supplemented by alternative formulation based on integration along sampling ray paths through the slab. Angular integrations are performed by the Gaussian quadrature method which determines the ray angles. Options may be exercised to determine the number of angles and the nature of the radiation boundary condition at one boundary of the transport region. The characteristic ray code differs from the current integral method in performing problems having a large number of zones more rapidly and in having more general boundary conditions. For most applications a small number of angles give adequate accuracy. The numerical method used in the ray code is described. In addition, the organization of the code is discussed and subroutines are listed.
