The grids in this directory are unstructured versions of the structured
One-to-One grids in directory Str-OnetoOne-A-v1.  Each mult-zone
structured grid was converted to a single zone unstructured hex grid 
by eliminating all duplicate nodes at the one-to-one 
interfaces.  The resulting files give all of the unique nodes, along 
with cell-to-node connectivity information for all the hex volumes, as well
as face-to-node connectivity information for all the quad boundary faces.
BC information is also included.

There are 4 grid levels for configuration 1 (extra-coarse, coarse, medium, 
and fine) and 1 grid level for configuration 8 (medium).  Note that an 
"extra-fine" grid was NOT created for configuration 1.

The grid sizes are as follows:

Fine:        161,853,985 points, 160,856,064 cells
Medium:       48,104,801 points,  47,661,056 cells
Coarse:       20,356,741 points,  20,107,008 cells
Extra-coarse:  6,068,737 points,   5,957,632 cells.

Note that the point count here is not the same as the point count for the
grids in Str-OnetoOne-A-v1, because here the duplicate points at
the one-to-one interfaces of the original grids have been eliminated.  
However, the cell count is the same.

Note that a CGNS version of the FINE Config1 grid could not be created
because the 4-byte integer limit was exceeded by the cell-to-node HEXA_8 
pointer array.  However, an AFLR3 version was created.
