 The restart file is an unformatted file that stores all of the 
flow-field information as well as the time-step information.  It is meant
to only be read in by the DUNS and DUNSPLOT codes.  It is set up such that a 
double-precision code can read either a single or double-precision restart
file, and vice-versa.  
 
 The plotting files are basically plot3d files, except they can contain
up to ten variables (plot3d files typically contain either four or five
variables, depending on whether they are 2d or 3d).  The variables
for plotting is defined on the first line of the duns-out.vfile.
An example of aduns-out.vfile is given below: 
 
p1 u v t nut
#
# The DUNS code only reads the first line, so we can put
# any comments we want below this line.
#
 The DUNS code will plot out the values at either cell centers or
cell vertices dependent on the value of ioutdefined in either the 
input script or input deck.  For a value ofiout=2, it will plot out
the value at the cell vertices.  For a value ofiout=1it will print
out the value at the cell centers, excluding ghost cells, and foriout=0it will print out cell center values including ghost cells. 
The last option is convenient if you are having problems and want to verify
that the boundaries are being set correctly.  The variables available for
plotting are:
