A second international AIAA Drag Prediction Workshop (DPW-II) was organized and held in Orlando, Florida on June 21-22, 2003. The primary purpose was to investigate the code-to-code uncertainty. address the sensitivity of the drag prediction to grid size and quantify the uncertainty in predicting nacelle/pylon drag increments at a transonic cruise condition. This paper presents an in-depth analysis of the DPW-II computational results from three state-of-the-art unstructured grid Navier-Stokes flow solvers exercised on similar families of tetrahedral grids. The flow solvers are USM3D--a tetrahedral cell-centered upwind solver, FUN3D--a tetrahedral node-centered upwind solver, and NSU3D--a general element node-centered central-differenced solver. For the wing/body, the total drag predicted for a constant-lift transonic cruise condition showed a decrease in code-to-code variation with grid refinement as expected.
