Abstract:

In the finite element approach to static structural analysis, the solution of the equation KU P a positive definite system of simultaneous linear equations is basic. However, the order of K is often so large that, when advantage is taken of Ks symmetry and banded structure, it is not feasible or sometimes even possible to store K in the core memory of a computer. SOLVEDG is an out-of-core system solver for KU P suggested by Cantins IBM 360 program SOLVE. SETUP is a preprocessor program for SOLVEDG which stores the matrices K and P in Random Access Files. SOLVEDG and SETUP are written in FORTRAN Extended for the CDC 6700 64006600. The report also contains an original proof justifying the basic algorithm of SOLVEDG. Author
