An international workshop on Drag Prediction took place in June 2009 in San Antonio, TX in association with the American Institute of Aeronautics and Astronautics. The objectives were multifold:

  1. To build on the success of past AIAA Drag Prediction Workshops.
  2. To assess the state-of-the-art computational methods as practical aerodynamic tools for aircraft force and moment prediction of industry relevant geometries.
  3. To provide an impartial forum for evaluating the effectiveness of existing computer codes and modeling techniques using Navier-Stokes solvers.
  4. To identify areas needing additional research and development.

CFS Engineering's results were presented and may be found here.

For this case study, a medium-grade mesh sufficiently captures important flow features compared to a fine mesh.
