The grids in this directory were created at DLR.
These are the UNSTRUCTURED mixed element grids built using the SOLAR package of ARA.
There is one grid level for Case 2 Config 4 (medium). 
Two different grids were built: one for use with low Re (1.35M) and for high Re (15.1M).
(This team also built grids for Case 1 (Config 2) and Case 3 (Config 5).)

The grid sizes are as follows:

Low-Re, medium:       no_of_gridpoints = 37,346,449   no_of_elements = 76,972,998
High-Re, medium:      no_of_gridpoints = 32,392,356   no_of_elements = 73,740,331
