The AIAA CFD Drag Prediction Workshop was held June 9-10, 2001 in Anaheim, CA. The workshop was held to assess the state-of-the-art in computational methods for aircraft force and moment prediction with emphasis placed on the prediction of drag polar and drag rise.
The test configuration was a DLR-F4 model which had been tested in three European transonic facilities. Participants were provided with multiblock structured, overset, and unstructured grids on which to perform baseline cruise-point calculations.
Twenty participants provided solutions and 51 individuals attended the workshop from the U.S., Canada, Europe, and Brazil. At the cruise point, the standard deviation of CFD solutions was 20 drag counts (0.0020), whereas the standard deviation in the wind tunnel data was approximately 5 drag counts. A similar workshop held in the 1990s used the same geometry and resulted in a standard deviation of approximately 50 drag counts.
The results and remarks are available online.

This week's CFD haiku comes from willjefc:
Computer our friend?
Try a small mesh size problem
Testing not so bad.
Send in your CFD haiku for publication here each week. There is no reward other than perhaps personal enlightenment. So, silence the mind, yield to spontaneity and send in your CFD haiku today.
