This paper presents a numerical method for aerodynamic shape optimization problems. It is based on simultaneous pseudotime-stepping in which the optimality is reached simultaneously with the state and costate feasibility. An optimization-based multigrid strategy results in efficient convergence of the method. The total effort of optimization is less than two forward simulation runs. (© 2008 WILEY-VCH Verlag GmbH & Co.
