51.19.1. Solution XY Plot Dialog Box

The Solution XY Plot dialog box allows you to display zone, surface and file data in an XY plot format. See Steps for Generating Solution XY Plots for details about the items below.

You can also access the Solution XY Plot dialog box through the Postprocessing ribbon tab.

Postprocessing → Plots → XY Plot → New...

Note:

The "global"/non-persistent form of graphics objects is hidden by default. If this interrupts your workflow, you can make them available by enabling the Expose legacy non-persistent graphics option in the Graphics branch of Preferences (accessed via File>Preferences...).
(When you click Edit... instead of New..., it opens the "global"/non-persistent version of the Solution XY Plot dialog box. This version of the dialog box does not have a Name field and it is not saved with the case file.
You are encouraged to use the persistent version that is accessed by clicking New....

Controls

XY Plot Name

is the name for a solution XY plot definition. You can specify a name or use the default name xy-plot-id. This control appears only for solution XY plot definitions.

Options

contains check buttons that control the presentation of node or cell-averaged values, the selection of axis functions, and the ability to write the plot data to a file.

Node Values: toggles the node averaging of the data presented in the plot. If the option is disabled, boundary face values are presented. See Choosing Node or Cell Values for details.
Position on X Axis, Position on Y Axis: set the -axis or -axis function to be the position. If one of these options is turned on, the other will automatically be turned off. You can turn both options off to generate a plot of one flow-field function vs. another, selecting the function for each axis using the X Axis Function and Y Axis Function drop-down lists.
Write to File: activates the file-writing option. When this option is selected, the Plot push button will change to Write.... Clicking on the Write... button will open the Select File dialog box (The Select File Dialog Box), in which you can specify a name and save a file containing the plot data. The format of this file is described in XY Plot File Format.
Order Points: specifies that plot data being saved to a file should be sorted in order of ascending axis value. This option is available only when the Write to File option is turned on.

Plot Direction

contains inputs for defining the plot direction.

If Direction Vector (the default) is selected in the X Axis Function or Y Axis Function drop-down list (whichever is the position axis), the inputs are the components of the direction vector. The position axis of the plot will have coordinate values that correspond to the dot product of the data coordinate vector with the plot direction vector. See Steps for Generating Solution XY Plots for details.

X: is the component in the direction.
Y: is the component in the direction.
Z: is the component in the direction.

If Curve Length is selected in the X Axis Function or Y Axis Function drop-down list (whichever is the position axis), the inputs are the direction along the length of the surface selected in the Surfaces list. See Steps for Generating Solution XY Plots for details.

Default: specifies the plot direction as the direction of increasing curve length.
Reverse: specifies the plot direction as the direction of decreasing curve length.
Show: displays the selected surface in the graphics window, marking the start of the surface with a blue dot and the end of the surface with a red dot. Ansys Fluent will also display arrows on the surface showing the direction in which the variable will be plotted.

Y Axis Function, X Axis Function

contain lists of solution variables that can be used for the or axis of the plot. If the Position on X Axis option is turned on, X Axis Function will become a single drop-down list, containing two options: Direction Vector (to plot the selected variable as a function of position along a specified direction vector) and Curve Length (to plot the selected variable as a function of position along the length of a specified curvilinear surface). See Steps for Generating Solution XY Plots for details.

Likewise, if Position on Y Axis is turned on, Y Axis Function will become a single drop-down list containing Direction Vector and Curve Length. If both Position on X Axis and Position on Y Axis are turned off, you can select field functions for both axes using the X Axis Function and Y Axis Function lists.

Note: When running the parallel version of Ansys Fluent, Curve Length is only supported when the curvilinear surface is contained within a single partition.

File Data

Color: sets the color of the active curve. A drop-down list allows you to select from a list of color names.
Weight: sets the thickness of the active curve. A line weight of 1.0 is normally 1 pixel wide. Therefore, a weight of 2.0 would make the line twice as thick (2 pixels wide).

Marker Style

contains controls for modifying the appearance of the active curve’s marker.

Symbol: sets the symbol used to mark data. You can select the symbol from a drop-down list that contains all the symbol choices. The Sample box will allow you to experiment with various markers. For example, in plotting pressure-coefficient data on the upper and lower surfaces of an airfoil, the symbol /*\ (filled-in upward-pointing triangle) could be used for the marker representing the upper surface data, and the symbol \*/ (filled-in downward-pointing triangle) could be used for the marker representing the lower surface data.
