The restart file is an unformatted file that stores all of the
flowfield information as well as the timestep information. It is meant
to only be read in by the DUNS and DUNSPLOT codes. It is set up such that a
doubleprecision code can read either a single or doubleprecision restart
file, and viceversa.
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 dunsout.v file.
An example of a dunsout.v file 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 iout defined in either the
input script or input deck. For a value of iout=2 , it will plot out
the value at the cell vertices. For a value of iout=1 it will print
out the value at the cell centers, excluding ghost cells, and for
iout=0 it 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:
