The accuracy of the DLR structured and unstructured computational fluid dynamic (CFD) codes in predicting aircraft forces and moments on a wing-body configuration at transonic speeds is investigated. The computations form the contribution of the DLR and Airbus Deutschland to the AIAA CFD Drag Prediction Workshop in June 2001. Using a combination of a high quality grid, low levels of artificial dissipation and an advanced turbulence model, the structured code (FLOWer) was able to both qualitatively and quantitativele predict the experimentally measured drag, lift and pitching moments. In its current implementation the unstructured code (TAU) was found to be less accurate in predicting forces and moments, although qualitatively the results were good.
