33.20.1 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 Section  29.9.2 for details about the items below.

Controls

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 inactive, cell values are presented. See Section  29.9.2 for details.

Position on X Axis, Position on Y Axis   set the $x$-axis or $y$-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 (see Section  2.1.6) (Section  2.1.6 and Section  2.1.6), in which you can specify a name and save a file containing the plot data. The format of this file is described in Section  29.9.6.

Order Points   specifies that plot data being saved to a file should be sorted in order of ascending $x$ 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 Section  29.9.2 for details.

X   is the component in the $x$ direction.

Y   is the component in the $y$ direction.

Z   is the component in the $z$ 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 Section  29.9.2 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 $y$ or $x$ 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 Section  29.9.2 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.

File Data   is a selectable list of the plot titles associated with the loaded external data files. You may choose any number of files for the data plot. The files are loaded using the Load File... push button. The format of these files is presented in Section  29.9.6. See Section  29.9.2 for details.

Load File...   opens the Select File dialog box (see Section  2.1.6) (Section  2.1.6 and Section  2.1.6), in which you can select the plot file to be read. See Section  29.9.2 for details. After the external file is loaded, its plot title will be displayed in the File Data list.

Free Data   removes the files selected in the File Data list.

Surfaces   is a selectable list of surfaces in the solution domain. You may choose any number of surfaces for the data plot.

New Surface   is a drop-down list button that contains a list of surface options:

Point   opens the Point Surface dialog box.

Line/Rake   opens the Line/Rake Surface dialog box.

Plane   opens the Plane Surface dialog box.

Quadric   opens the Quadric Surface dialog box.

Iso-Surface   opens the Iso-Surface dialog box.

Iso-Clip   opens the Iso-Clip dialog box.

Plot   plots the specified surface and/or file data in the active graphics window using the current axis and curve attributes. If the Write to File option is turned on, this button becomes the Write... button.

Write...   opens the Select File dialog box (see Section  2.1.6) (Section  2.1.6 and Section  2.1.6), in which you can save the plot data to a file. This button replaces the Plot button when the Write to File option is turned on.

Axes...   opens the Axes dialog box, which allows you to customize the plot axes.

Curves...   opens the Curves dialog box, which allows you to customize the curves used in the XY plot.
