Geometry and Function Definition for Discrete Analysis and Its Relationship to the Design Data Base.
Abstract
The purpose of this paper is to discuss data requirements for structural analysis, in order to clarify its dependence on the design process as a whole. The model generation capabilities of a state-of-the-art structural analysis system (GIFTS 4), heavily oriented towards pre-and post-processing and computer graphics, is presented. The system is capable of generating points, curves, surfaces, and solids in a hierarchical manner. It recognizes that geometric definition is only a part, albeit a fundamental part, of the structural system definition. The geometric components are used as a reference geometry, upon which the user may define loading patterns, kinematic boundary conditions, material property variation and so on. It is in linking these items together with the geometry that a structural analysis becomes feasible. In presenting and discussing the data base requirements for a structural analysis in a consistent manner, the designer of a CAD system is presented with basic data requirements to be included in his data base design.
