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.
