29.9.6 XY Plot File Format

The XY file format read or written by ANSYS FLUENT includes the following information:

• The title of the plot

• The label for the abscissa and the ordinate

• Cortex variables and pairs of abscissa/ordinate data for each curve in the plot

The following sample file illustrates the XY file format:

(title "Velocity Magnitude")
(labels "Position" "Velocity Magnitude")

((xy/key/label "pressure-inlet-8")
 (xy/key/visible? #t)
 (xy/line/pattern "--")
0.0000 230.097
0.0625 160.551
0.1250 149.205
...
0.5000 183.007
)

Similar to the case file format, parentheses bound the various pieces of information in the formatted, ASCII file. The title (title " ") and labels (labels " ") must be first in the file, then each curve has information in the form ((cxvar value) x y x y x y ...), where there may be zero or more Cortex variables defined for each curve.

You do not have to include Cortex variables to import your XY data. For example, you may wish to import experimental data to compare with the ANSYS FLUENT solution. The following example would use the default Cortex variables in the code to define the data. After you import the file into ANSYS FLUENT, you could then use the Axes dialog box and the Curves dialog box to customize the XY plot, as described in Sections  29.9.9 and 29.9.10.

(title "Experiment, Run 11")
(labels "X, m" "Cp")
(0 1.5
  1.5 1.3
  3.2 1.5
  5.1 1.2
)
