Population-based Search, Shape Optimisation and Computational Expense

Abstract

Shape optimisation has been very much in evidence from the early days of evolutionary design (e.g., Klockgether J., Schweffel H-P., 1970; Pinebrook E., Dalton C., 1983). Examples include topological and dimensional variation to satisfy deflection, stress and/or weight criteria or to minimise losses/maximise lift upon a body placed in fluid flow. These, amongst others, are reviewed in the following section. During the final stages of detailed design, however, such shape variation invariably involves the utilisation of complex analysis software as a means of assessing solution fitness. Both CFD and FEA techniques play a major role.
