The Aero Grid and Paneling System (AGPS) is an interactive, three-dimensional, parametric, surface modeling programming language. It features superior geometry creation, modification, analysis, computational pre-processing and graphic post-processing capabilities necessary for effective and rapid engineering use. AGPS includes extensive curve, surface, and volume generation options, curve and surface intersection algorithms, raster imaging, structured/unstructured grid extraction, several supported input formats, and a flexible output capability for interfacing with any engineering analysis codes.
