DPW4 Grids

The tar files below include the VGRID files: igs, d3m, mapbc, cogsg,
front, poin1, and bc files.  These grids have been generated by Cessna 
and post-processed for quality improvement at NASA. The rate of growth 
of viscous layers in these grids are higher than those generated at
NASA. For VGRID file formats, refer to the VGRID_FILE_FORMATS.txt file.

All of these grids were generated using GridTool Version 4.1 and
the 64-bit VGRID version 4.2. 

There are some volume sources used in these grids, so if the grids are regrown with 
an earlier version of VGRID, the restart files will have to be modified for this. 
All grids but the last listed were generated for a Reynolds number of 5 million based
on the reference chord.
