1. NAME AND TITLE

MRSPAK: A Code System To Generate a Text File Containing Combinatorial Geometry Data Corresponding to PADL2 Geometry.

2. CONTRIBUTOR

Sandia National Laboratories, Albuquerque, New Mexico.

3. CODING LANGUAGE AND COMPUTER

FLEX; VAX 11.

4. NATURE OF PROBLEM SOLVED

MRSPAK is a suite of subroutines which generates a text file containing combinatorial geometry for use with the PADL2 system.

5. METHOD OF SOLUTION

MRSPAK generates a text file containing combinatorial geometry data corresponding to PADL2 geometry. This allows users of MORSE, ACCEPT, and other radiation transport analysis packages based on combinatorial geometry, to create geometry using the PADL2 system and then automatically generate the combinatorial geometry data from the PADL2 representation. This is desirable since creating geometry data in the combinatorial geometry format is tedious and error-prone.

6. RESTRICTIONS OR LIMITATIONS

The package is designed for the VAX family of computers and runs under VMS. The PADL2 package, a proprietary software from the University of Rochester, Rochester, New York, must also be available.

7. TYPICAL RUNNING TIME

No study has been made by RSIC of typical running time for MRSPAK.

8. COMPUTER HARDWARE REQUIREMENTS

The code was designed to run on the VAX under VMS.

9. COMPUTER SOFTWARE REQUIREMENTS

MRSPAK is written in FLEX, a Fortran pre-processor, which is distributed as part of PADL2 by the University of Rochester.

11. CONTENTS OF CODE PACKAGE

Included are the referenced document and one (1.2MB) DOS diskette which contains the source codes.
