Interactive Nonlinear Structural Analysis: Enhancement.

Abstract

GIST is a system for performing Nonlinear Finite-Element Structural Analysis in an Interactive, Graphics-Oriented computational environment. The system constitutes a network of integrated software processors, i.e., independently executable computer programs, collectively referred to as the GIFTS/STAGS Software Assembly, or more concisely as GIST. This network is analogous to a computer operating system, which enables the user to perform a wide variety of operations accessible through a common 'command' (or 'control') language. Many of these operations are actually performed by independent processors which are linked through a 'global database' to behave as an integrated system. Thus, GIST may be regarded as a special-purpose (or 'virtual') operating system for structural analysis, where instead of text editors, compilers and file handlers, GIST employs model editors, structural analyzers and solution post-processors as basic components. Furthermore, the user addresses the GIST 'operating system' in a Problem-Oriented Command Language, and is free (by virtue of the global database) to exercise the system in a 'reasonably' arbitrary fashion, with frequent stops and restarts.
