GPRIME/GGEN Interactive Finite Element Data Generator.
Abstract
The GPRIME/GGEN interactive general finite element data generator is a computer software system which generates finite-element models from GPRIME geometric descriptions of structures. GGEN permits interactive generation of two-dimensional elements with uniform or non-uniform meshes, with user options on node and element numbering. The user may create these data in large quantity with a single keyboard command, or in smaller groups or singly either by keyboard command or graphic control. Nodes and elements may be changed or deleted with either keyboard commands or cursor controls. Display features include scaling, translations, and rotations as well as selection of items to be displayed. The output file consists of grid point data coordinates and element connection data. Error messages are designed to enable the user to recover from errors and to continue the GGEN process. The GGEN data generator is designed as an applications program using the GPRIME geometric language and language processor. GPRIME features available at any time during the GGEN modeling process include GPRIME processing of changes, print options, HELP messages, new geometry, access to existing geometry, viewing options, and restart capability.
