I3G VIRGO Interactive Graphics for Geometry Generation and Visual Interactive Rapid Grid Generation. User's Manual

Abstract

I3G/VIRGO uses interactive computer graphics to display the geometric model as it is being manipulated or built. The user views, picks, and manipulates geometries via mouse and keyboard inputs and is provided the flexibility to generate both the surface and field grids of complex configurations. Because the user visually sees what is being generated, errors are easier to detect, and fewer are made. Discussions were held with experienced analysis code users prior to the design of I3G and VIRGO, and continual inputs during development have assured an optimal human interface. The operation of I3G/VIRGO is intimately tied to its use of menu selecting and prompting to allow both the experienced and uninitiated user to input information easily. The program also contains an on-line help capability that can be requested by the user at any point during program operation. (KR)
