The GPRIME Approach to Geometric Modeling: Introduction to the Language Processor and Finite Element Applications.

摘要

The role of geometric modeling in the evolving field of automated analysis and design has shown the need for complete geometric representations of structures. The GPRIME geometric modeling system is at the fore-front of the interactive systems addressing this need. The GPRIME system consists of an interactive geometric modeler and for finite element data generators. GGEN is used to generate general finite elements, particularly two-dimensional elements. SOLIDGEN is used in three-dimensional solid modeling. Both GGEN and SOLIDGEN are dependent on the geometric model defined in GPRIME. This report summarizes both the development of geometric modeling in automated design and analysis and the GPRIME geometric modeling system. (Author)
