Abstract
Computational fluid dynamics (CFD)-based optimization of a surface combatant was discussed. The objectives of surface combatant were development of a high-performance optimization module for a Reynolds averaged Navier-Stokes (RANS) solver for with-free-surface condition; and demonstration of the capability of the optimization method for flow-and wave-field optimization of the Model 5415 hull form. The optimization module was based on extension of successive quadratic programming (SQP) for higher-performance optimization method by introduction of parallel computing architecture. It was observed that parallel SQP module was nearly m (=2k+1; k was number of design parameters) times faster than conventional succesive quadratic programming(SQP).
