These meshes are merged mixed-element versions of the original tet grids
D_uns_tet_Case1Config2_v2/fine/CorrectedGrid/dlrf11_config2_vgrid_fine_rbl2.
The original grid was generated with GridTool/VGrid at Cessna.
But it was discovered that the D fine grid was made with
incorrect min spacing at walls.  It should have been 0.00024, but it was mistakenly
created with the medium grid spacing of 0.00037.  This was corrected after the
workshop on 3/14/2014 (by e.lee-rausch@nasa.gov).

The corrected files are provided in this directory.

Grid is in mm.

NOTE: There is a y shift of approximately 0.01 mm the surface geometry.
Independent tests were made to verify the effect of this shift is negligible.
