GEOCES: A Gaussian Elimination Out-of-Core Equation Solver,

Abstract

In the finite element approach to structural analysis the solution of the equation KU = P is basic. K is usually a banded matrix which is symmetric and positive definite. However in certain areas such as fluid-structures interaction problems K may be a non-symmetric banded matrix. Further the order of K is often so large that, even when the banded structure of K is taken into account, the storage of K in the core memory of a computer may not be feasible or even possible. GEOCES is a Gaussian elimination out-of-core equation solver for non-symmetric banded systems of linear equations. GEOCES should be regarded as experimental rather than as a production program. GEOCES is written in FORTRAN Extended for the CDC 6000 series of computers with respect to the SCOPE 3.4 operating system and assumes the availability of random access scratch files. (Author)
