 The files found within these directories serve three purposes:
 
-1. A subset of the available cases are used for regression testing internally by the development team. The configuration files and meshes are automatically downloaded and executed with the latest version of SU2 at regular intervals. Any changes in the output of the specified test cases are immediately reported to the developers.

The configuration files and meshes are automatically downloaded and executed with the latest version of SU2 at regular intervals. Any changes in the output of the specified test cases are immediately reported to the developers. These cases are controlled by the Python scripts in the root of the test cases directory, e.g., serial_regression.py.
 
-2. A subset of the available cases contain the configuration files and meshes that are required for the written tutorials found in the SU2 documentation (see http://su2.stanford.edu/training.html).

-3. The entire suite of test cases is provided to the community as a way to get started with SU2 and its many configuration options (including settings that the developers consider to be good starting points). Often, you will find a test case that is similar to your problem of interest, and the available configuration files can be modified to suit your needs.

 Note that, while many of the cases are used for regression testing, this test case suite is provided without any guarantees on performance or expected results. Keep in mind that small changes to the configuration options can often result in large changes to the output. We encourage the community to experiment with these test cases, or even try (and share!) other interesting validation cases with SU2!
