The grids in this directory were created at DLR.
These are the UNSTRUCTURED mixed element grids built using the SOLAR package of ARA.
There are 3 grid levels for Case 1 Config 2 (coarse, medium, and fine).
(This team also built grids for Case 2 (Config 4) and Case 3 (Config 5).)

The grid sizes are as follows:

Fine:        no_of_gridpoints = 73,421,980    no_of_elements =165,246,813
Medium:      no_of_gridpoints = 25,574,796    no_of_elements = 59,066,549
Coarse:      no_of_gridpoints =  9,168,002    no_of_elements = 21,356,048
