Do not consider the data in this report the "correct" answer. The computations for this workshop will be fully turbulent. We are not necessarily testing how well we can match wind tunnel data (you will note the drag data is provided with only 2 significant digits). The statistical analysis will emphasize the comparisons within the computational results.

Statistical Framework:

The following link describes the statistical framework that will be used to compare the code results from the participants and includes a detailed example based on the results from a similar, but less extensive, study done in Europe. Statistical Framework
