Abstract
A parallel variable-complexity modeling approach, permitting the
efficient use of emerging parallel computing in multidisciplinary
optimization (MDO) technology, is presented for the particular instance
of High Speed Civil Transport (HSCT) design. Simple analyses are used
to limit the approximation domain in the design space. Points are
selected within the approximation domain by a genetic algorithm based on the
D-optimality criterion. At the selected points, a refined analysis is
performed. The optimization code is composed of a sequence of analysis
cycles between aerodynamic and structural calculations. A coarse
grained parallelization of the aerodynamic code is presented.
