A grid generation system for multi-disciplinary design optimization

Abstract

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 ASCH 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 a complex HSCT configuration including horizontal and vertical tails, engine nacelles and pylons, and canard surfaces.
