Abstract
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.
