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.
