1. NAME AND TITLE
ADO: Aerojet Discrete Ordinates Calculational System.
Included within ADO are the One- and Two-Dimensional Codes ANISN, DOTT III, FAMORSE; with Auxiliary Routines DASH, MONDRIAN, and TAPEMAKER.
Aerojet Nuclear Systems Company, Sacramento, California.
3. CODING LANGUAGE AND COMPUTER
FORTRAN IV; UNIVAC 1108 (A) and IBM 360/370 (B).
4. NATURE OF PROBLEM SOLVED
ADO is a radiation analysis computer code collection developed in support of the NERVA nuclear rocket program. It includes the discrete ordinates/Monte Carlo coupling capability.
All of the three-dimensional point kernel and Monte Carlo codes have a common geometry routine which allows the user to prepare a single model with options for sophisticated or simple analyses at any time after the model is once checked out for errors.
5. METHOD OF SOLUTION
Monte Carlo is among the methods employed in the ADO system.
6. RESTRICTIONS OR LIMITATIONS
7. TYPICAL RUNNING TIME
The time required for ADO to execute depends entirely on the problem and the number of ADO routines called.
8. COMPUTER HARDWARE REQUIREMENTS
ADO is operable on the UNIVAC 1108 or the IBM 360/370 computers.
9. COMPUTER SOFTWARE REQUIREMENTS
A FORTRAN IV compiler is required.
