DPW4 Grid Files
                     (February 11, 2009)

The tar files below include the GridTool restart file (rst), 
VGRID files (bbx, igs, d3m, mapbc, cogsg, front, poin1, bc),
and CGNS files (cgns). These grids are tetrahedral and for 
node-based solvers (containing approximately 3.5, 10, 35, and
100 million nodes). For VGRID file formats, refer to the 
VGRID_FILE_FORMATS.txt file. Grid files are also available in 
the CGNS format for all grids except the extrat file grid. For 
CGNS file format, see http://cgns.sourceforge.net/

All of these grids were created using GridTool Version 4.2 and
the 32- and 64-bit versions of VGRID/POSTGRID 4.2.

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

1) dpw-wb0_med-7Mn_5.tgz            Tail off, size = medium. 
                                    Grid at the tail location is coarse.
                                    Re=5M, dy=0.000985.

2) dpw-wb0_med-8Mn_5.tgz            Tail off, size = medium. 
                                    Grid at the tail location is fine and 
                                    compatible with other grids with tail on.
