The grids in this directory were created at DLR.
They are unstructured mixed element grids, created
using Centaur v8.1.3 and intended for node-centered
flow solvers. The grids are made up of a
mix of tetrahedra, prisms, and pyramids.

To date, a complete set of grids could not be
completed.  So far the only available grids are for
Config 1: medium, coarse and extra-coarse levels.

The grid sizes are:

Medium:       31,498,984 points (78,725,517 elements)
Coarse:       16,374,761 points (43,548,725 elements)
Extra-Coarse: 12,923,391 points (37,418,633 elements)
