One mesh for the 25D flow through nacelle test cases that has
high-quality meshing for sonic boom analysis is provided.  The mesh
has a refined near body mesh with viscous spacing that produces a Y+
of 1 (initial viscous spacing is 0.00001 m) and a Mach cone aligned
outer volume grid. Beta-CAE ANSA surface mesher was used for the
surface grid and Pointwise volume mesher was used. Grids provided by
Susan Cliff of NASA Ames. These purely-tetrahedral grids are in full
scale meters and are intended for 0 deg angle of attack, Mach
1.60. See the README three levels up for details.

The extent of the outer boundary prevents the extraction of near field
pressure signatures at 5 body lengths.

The grid files contain 5 boundary patches:
- patch 1 is the aircraft outer mold line
- patch 2 is y-symmetry
- patch 3 is inflow
- patch 4 is outflow
- patch 5 is a far field boundary
