The grids in this directory were created at University of Wyoming.
They are unstructured tetrahedral grids, designed for node-centered
CFD codes.  There are 3 grid levels for configuration 1 (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 for Config 1:

Fine:        32,297,530 nodes (189,895,740 tetrahedra)
Medium:      10,957,783 nodes ( 64,441,259 tetrahedra)
Coarse:       3,652,657 nodes ( 21,492,137 tetrahedra)

For Config 8:

Medium:      11,524,779 nodes ( 67,783,972 tetrahedra)
