Interactive generation of unstructured grids for three dimensional problems

The present interactive grid-generation capability for unstructured grids substantially bases itself on the performance available in the most advanced workstations, in order to obviate much of the input, error-checking, and output process burden associated with the generation of grids in three dimensions. The illustrative examples presented encompass the B-747 wing-fuselage configuration, a generic wing-fuselage-tail pathfinder configuration in a wind tunnel, and a generic train configuration in which surface data are not required to have very high accuracy, but many configurations must be analyzed rapidly.
