DTF4; one-dimensional, multigroup discrete ordinate program. [IBM360; CDC6600; GE625; FORTRAN IV (CDC6600), FORTRAN IV and MAP (GE625), FORTRAN IV and BAL (IBM360)]
The linear, time-independent, Boltzmann equation for particle transport is solved for the energy space, and angular dependence of the particle distribution in one-dimensional slabs, cylinders, and spheres. Independent source or eigenvalue (multiplication, time-absorption, element concentration, zone thickness or system dimension) problems are solved subject to vacuum, reflective, or periodic boundary conditions. A complete energy-transfer scattering matrix is allowed for each Legendre component of the scattering cross section matrices.IBM360;CDC6600;GE625; FORTRAN IV (CDC6600), FORTRAN IV and MAP (GE625), FORTRAN IV and BAL (IBM360); OS/360 (IBM360), and SCOPE (CDC6600); No disks or tapes are used. A clock is used but, by removing a few program statements, this requirement can be eliminated.
