Scalar Controls Reference

These settings give you control over labels and point sizes.

Isoline Labels Properties

Point Size: Sets the point size in pixels.
Visible: When activated, shows the labels and points in the scene.
Label Font: Selects the font of the labels.
Label Style: Uses a drop-down list to display the labels as normal, bold, italic or bold and italic.
Label Color: Sets the color to display the labels. The property customizer executes the define color action. See Defining Colors.
Label Precision: Specifies the total number of digits in the label. Raising this number adds decimal places.
Shadow: When activated, adds a shadow effect to the labels.
Point Color: Sets the color to display the points. The property customizer executes the define color action. See Defining Colors.
Label Size: Sets label size as a percentage of window size.

Point Size Node Properties

The Point Size node is activated by the default Pixels setting of the Point Scale Mode property of the scalar displayer. It sets the screen display size of a point in pixels in its Size property, independent of the physical size of the point. This option is likely to be useful when you want to display the points on a presentation grid. Lagrangian particles or parcels are not sized according to their physical size if this option is chosen.

Point Size Scale Field Node Properties

The Point Size Scale Field lets you scale a point’s screen dimension based on scalar quantity, such as particle size or fluid temperature. It is represented by the Point Size Scale Field node, which is activated when you set the Point Scale Mode property of the scalar displayer to Scalar.

In the properties, select a scalar field function on which to base the screen point size. The size of the particle on the screen is calculated relative to the overall dimensions of the mesh. An exaggerated example of this is shown below.

If you want to scale by something else (such as velocity), map the velocity range to a physical size range, where the physical size range sets the minimum and maximum size of particles relative to the mesh dimensions. Activate the Map values property to activate this mapping. The formula that is used for the mapping is:

Point Size = (Scalar Value - Min) (\frac{Map size maximum - Map size minimum}{Max - Min}) + Map size minimum

which means that is mapping values in interval [Min, Max] to interval [Map size minimum, Map size maximum].

Function

Selects the type of scalar field function or field function monitor to show, such as temperature or velocity magnitude. See What Is a Field Function Monitor? and Field Functions.

Auto Min

Indicates the minimum value among all parts in the displayer (read-only).

Auto Max

Indicates the maximum value among all parts in the displayer (read-only).

Auto Range

Determines whether to set automatically the range of values to display:

Off—Does not use auto ranging, rather uses the values that are set in Min and Max.
Min and Max Values—Automatically determines the range from the field function data.
Min Value—Automatically determines the minimum value from the field function data. The property switches automatically from Min and Max Values to this setting if you make an entry for Max Value.
Max Value—Automatically determines the maximum value from the field function data. The property switches automatically from Min and Max Values to this setting if you make an entry for Min Value.

Auto Range Mode

Chooses the domain for auto-range minimum and maximum value computation that is used for color coding.

Displayer Parts—Parts added to the particular displayer.
Displayer Regions—Regions from which the displayer extracts data.
All Regions—All regions in the simulation.

Clip

Determines how to display values outside of the range that is specified by Min and Max:

Off—Values above Max are displayed in the maximum color, and values below Min are displayed in the minimum color.
Below Min, Above Max—Does not display values outside the range.
Below Min—Does not display values below Min.
Above Max—Does not display values above Max.

Units

Selects the type of units to display.

Min

Sets the minimum scalar value to include in the displayed range.

Max

Sets the maximum scalar value to include in the displayed range.

Map Values

When activated, displays the range with the Min and Max properties.

Note	In the event that Point Size Scale Field range values for Min and Max are the same, and you have Map Values activated, you must scale the points with custom settings. Specifically, enter values for Map Size Minimum and Map Size Maximum that are greater than the default values of zero.

Map Size Minimum

The physical size of the particle that represents the Min scalar value. The size is relative to the overall dimension of the mesh.

Map Size Maximum

The physical size of the particle that represents the Max scalar value. The size is relative to the overall dimension of the mesh. Some graphics hardware may impose a limit on how large this size can be.
