32.7.2 Display/Contours...

The Display/Contours... menu item opens the Contours panel.



Contours Panel


The Contours panel controls the display of contour and profile plots. See Section  28.1.2 for details about the items below.

Controls

Options   contains the check buttons that set various contour display options.
Filled   toggles between filled contours and line contours.

Node Values   toggles between using scalar field values at nodes and at cell centers for computing the contours. When the Filled option is off, Node Values is always on. See Section  28.1.2 for details.

Global Range   toggles between basing the minimum and maximum values on the range of values on the selected surfaces (off), and basing them on the range of values in the entire domain (on, the default).

Auto Range   toggles between automatic and manual setting of the contour range. Any time you change the Contours of selection, Auto Range is reset to on.

Clip to Range   determines whether or not values outside the prescribed Min/ Max range are contoured when using Filled contours. If selected, values outside the range will not be contoured. If not selected, values below the Min value will be colored with the lowest color on the color scale, and values above the Max value will be colored with the highest color on the color scale. See Section  28.1.2 for details.

Draw Profiles   causes the addition of a profile plot to the contour plot. The Profile Options panel is opened when Draw Profiles is selected.

Draw Grid   toggles between displaying and not displaying the grid. The Grid Display panel is opened when Draw Grid is selected.

Levels   sets the number of contour levels that are displayed.

Setup   indicates the ID number of the contour setup. For frequently used combinations of contour fields and options, you can store the information needed to generate the contour plot by specifying a Setup number and setting up the desired information in the Contours panel. See Section  28.1.2 for details.

Surface Name Pattern   specifies the pattern to look for in the names of surfaces. Type the pattern in the text field and click Match to select (or deselect) the zones in the Surfaces list with names that match the specified pattern. See Section  28.1.2 for information about matching additional characters using * and ?.

Contours of   contains a list from which you can select the scalar field to be contoured.

Min   shows the minimum value of the scalar field. If Auto Range is off, you can set the minimum by typing a new value.

Max   shows the maximum value of the scalar field. If Auto Range is off, you can set the maximum by typing a new value.

Surfaces   contains a list from which you can select the surfaces on which to draw contours. For 2D cases, if no surface is selected, contouring is done on the entire domain. For 3D cases, you must always select at least one surface.

Surface Types   contains a selectable list of types of surfaces. If you select (or deselect) an item in this list, all surfaces of that type will be selected (or deselected) automatically in the Surfaces list.

Display   draws the contours in the active graphics window.

Compute   calculates the scalar field and updates the Min and Max values (even when Auto Range is off).



Profile Options Panel


The Profile Options panel controls the scaling and projection direction of profiles. It is opened from the Contours panel, and you will display the profiles using the Display button in that panel. See Section  28.1.2 for details about the items below.

Reference Value   sets the "zero height'' reference value for the profile. Any point on the profile with a value equal to the Reference Value will be plotted exactly on the defining surface. Values greater than the Reference Value will be projected ahead of the surface (in the direction of Projection Dir. and scaled by Scale Factor), and values less than the Reference Value will be projected behind the surface.

Scale Factor   sets the length scale factor for projection. After subtracting off the Reference Value, FLUENT multiplies the resulting solution value by the Scale Factor to form a length.

Projection Dir.   sets the direction in which profiles are projected. In 2D, for example, a contour plot of pressure on the entire domain can be projected in the $z$ direction to form a carpet plot, or a contour plot of $x$ velocity on a sequence of $x$-coordinate slice lines can be projected in the $x$ direction to form a series of velocity profiles.
