A Grid Generation System for Multi-disciplinary Design Optimization

A general multi-block three-dimensional volume grid generator is presented which is suitable for Multi-disciplinary Design Optimization. The code is timely, robust, highly automated, and written in ANSI "C" for platform independence. Algebraic techniques are used to generate and/or modify block face and volume grids to reflect geometric changes resulting from design optimization. Volume grids are generated/modified in a batch environment and controlled via an ASCII user input deck. This allows the code to be incorporated directly into the design loop. Generated volume grids are presented for a High Speed Civil Transport (HSCT) Wing/Body geometry as well as a complex HSCT configuration including horizontal and veritcal tails, engine nacelles and pylons, and canard surfaces.
