Medium grid
* Created by scaling the fine grid blocking file using an ICEM HEXA script and a scale factor of 1.5; 
  the grid was then regenerated using HEXA and the scaled blocking file.
* 320 zones
* 34,255,820 points
* Viscous spacing = 0.000435 mm
* Grid is in mm.
* Note that these grids have been built in the -y plane. This needs to be taken into
  account when postprocessing.

File Types Provided:
   1. Plot3d type
         .p3d  = Plot3d, double-precision, big endian unformatted
         .nmf  = Neutral Map File info (dimensions, BCs, and connectivity)
                    (see http://geolab.larc.nasa.gov/Volume/Doc/nmf.htm)
   2. CGNS type (includes all grid, connectivity, and BC information)
         .cgns = CGNS file (see www.cgns.org)
                 (file conversion from PLOT3D to CGNS format was done
                 by C. Rumsey... c.l.rumsey@nasa.gov)
   3. *blk and *tin files from ICEM Version 13 are also included.

      If using the *blk and *tin files, they employed a slightly
      incorrect positioning of the aircraft.  The following
      transformation may be necessary if you build grids anew from
      these files:
                 y(i,j,k)=y(i,j,k)+.009999973987
                 z(i,j,k)=z(i,j,k)-.001
      Please check any grids that you create carefully against
      existing approved posted grids.
