Abstract

GRAFFIC is a three-dimensional graphics computer package which provides interpretation and display facilities for numerical predictions of phenomena involving fluid-flow and heat/mass transfer. It is designed for use as a pre- and post-processor for solution methods of the finite-domain or finite-difference type. GRAFFIC operates interactively, using a storage-type graphics terminal, with associated hard-copy units if required. Communication with the user is via a series of meaningful prompts, designed to make the operation self explanatory.

Facilities provided by GRAFFIC include representation of the flow geometry and solution mesh, contour maps and surfaces of scalar fields, and vector fields represented either by vector maps on selected planes or vector lines or streamlines. For two-phase flow computations, GRAFFIC provides separate representation of the velocities and other properties of each phase.

A range of view options are provided including: perspective from a specified viewpoint; oblique views; two-dimensional side, top and end views; and a stereoscopic effect provided by two perspective views at a small displacement.

The paper provides a description of the structure and organisation of GRAFFIC and illustrates its use by showing applications to results obtained from the PHOENICS program.
