TRIDENT; 2-dimensional multigroup transport triangular mesh. [CDC7600; IBM360,370; FORTRAN IV (TRIDENT source and routines) and IBM360 Assembler (subroutines ABEND, DATE, SECOND, TIME, TRACER, CONVO, and CONVI)]

Technical Report ·
OSTI ID:6320121

TRIDENT solves the two-dimensional, multigroup transport equations in rectangular (x-y) and cylindrical (r-z) geometries using a regular triangular mesh. Regular and adjoint, inhomogeneous and homogeneous (keff and eigenvalue search) problems subject to vacuum, reflective, white, or source boundary conditions are solved. General anisotropic scattering is allowed and anisotropic distributed sources are permitted.CDC7600;IBM360,370; FORTRAN IV (TRIDENT source and routines) and IBM360 Assembler (subroutines ABEND, DATE, SECOND, TIME, TRACER, CONVO, and CONVI); OS/360 MVT (IBM360), SCOPE (CDC7600); A maximum of three interface file units open at one time and three system input-output units are required. One random disk unit is required if the automatic data overflow option is used. 730K bytes of memory are necessary to execute the sample problems on the IBM system. The amount of memory needed is problem-dependent. A LCM block of 131,064 words was needed to execute the sample problems on the CDC7600.
