RSIC CODE PACKAGE PSR-251


1. NAME AND TITLE

DSNQUAD: Calculates Angular Quadrature Weights and Cosines.

2. CONTRIBUTOR

Battelle Columbus Laboratories, Columbus, Ohio.

3. CODING LANGUAGE AND COMPUTER

Fortran 77; IBM PC and compatibles.

4. NATURE OF PROBLEM SOLVED

DSNQUAD calculates the angular quadrature weights and cosines for use in CCC-254/ANISN-ORNL. The subroutines in DSNQUAD were lifted from the XSDRN-PM code, which is supplied with the CCC-475/ SCALIAS-77 package.

5. METHOD OF SOLUTION

DSNQUAD runs interactively. The user is prompted for the geometry type (either slab, cylinder or sphere) and the degree of quadrature. The program then writes a file called DSNQUAD.OUT which is to be input to CCC-254/ANISN-ORNL.

6. RESTRICTIONS OR LIMITATIONS

None noted.

7. TYPICAL RUNNING TIME

Average running time for DSNQUAD takes a few seconds on the IBM PC/XT.

8. COMPUTER HARDWARE REQUIREMENTS

The code runs on an IBM PC or compatible, with or without a math co-processor.

9. COMPUTER SOFTWARE REQUIREMENTS

MICROSOFT Fortran 77 Version 4.01 was used to test the program. Alternatively, the IBM Professional Fortran compiler may be used.

10. REFERENCE

R. W. Tayloe, "DSNQUAD.DOC," Informal notes (September 1987).

11. CONTENTS OF CODE PACKAGE

Included are the referenced document and one (360 K) DOS diskette which contains the source and executable files, documentation and sample output.

12. DATE OF ABSTRACT

September 1989.
