The conference was organised around a number of parallel symposia, regular sessions, and keynote lectures focused on surrogate-based optimization in aerodynamic design, adjoint methods for steady & unsteady optimization, multi-disciplinary design optimization, holistic optimization in marine design, game strategies combined with evolutionary.

Dual time‐stepping schemes are recommended for the simulation of unsteady flow. In order to realize the potential benefits of CFD, it is essential to move beyond simulation to aerodynamic (and ultimately multidisciplinary) optimization. The article concludes with a discussion of aerodynamic shape optimization via control theory.

In case an implicit or discrete adjoint formulation is chosen to solve a problem, one can chose two linear solvers. I had this situation long ago with the 2nd-order Roe scheme for the viscous or inviscid flow around a wing, wing-body or airfoils using the Fluent.

It should be appreciated that the complex aerodynamics of a wing and body combination might result in an ac location which is not at the quarter chord point.
