RSICC CODE PACKAGE CCC-817

 

1. NAME AND TITLE

OPTIM: Minimization of Band-Width of Finite Elements Problems.

 

2. CONTRIBUTOR

AEE Winfrith, Dorchester, Dorset, United Kingdom through the OECD Nuclear Energy Agency Data Bank, Issy-les-Moulineaux, France.

3. CODING LANGUAGE AND COMPUTER

Fortran IV; IBM 370 Series (C00817I037000).

 

4. NATURE OF PROBLEM SOLVED

OPTIM minimizes the band-width of finite element problems.

 

5. METHOD OF SOLUTION

A surface is constructed from the x-y-coordinates of each node using its node number as z-value. This surface consists of triangles. Nodes are renumbered in such a way as to minimize the surface area.

 

6. RESTRICTIONS OR LIMITATIONS

This program is applicable to 2-D problems. It is dimensioned for a maximum of 1000 elements.

 

7. TYPICAL RUNNING TIME

Not provided.

 

8. COMPUTER HARDWARE REQUIREMENTS

IBM 370 Series.

 

9. COMPUTER SOFTWARE REQUIREMENTS

Standard IBM OS MVT.
