摘要：

The derivation of adjoint CFD codes through automatic differentiation is discussed with focus on the verification of the resulting code. Two alternative time-stepping formulations are discussed and compared, and the inclusion of multi-grid acceleration in the AD-derived code is shown. The adjoint code is embedded in a one-shot design loop and results for an inverse design case are presented. (C) 2011 Elsevier Ltd. All rights reserved.
