Results

Derived Data objects enable you to take samples of solution data at certain positions based on specific coordinates or intervals. The following types of derived data are available:

Point probe—defines a single point location.
Line probe—consists of evenly spaced points along a line.

The data value that is extracted for a particular point equals the cell value or surface value—whichever is closest in Eucledian distance to the point. If a point lies outside of the geometry, it extracts the surface cell value of the face that is closest to the point.

The Electronics Cooling Module offers two possibilities to analyze these data:

Plots—extract solution data from Derived Data objects and display them in two-dimensional graphs.
Reports—apply statistical functions to solution data, such as maximum, minimum, and average functions. The solution data can be extracted from Derived Data objects or from QuickParts.

Derived Data

The following properties are common to all Derived Data objects:


Common Properties
Name	Specifies the name of the Derived Data object under which it is stored in the tree.
QuickParts	Specifies the QuickParts that are used as the source for extracting solution data.

You can position point and line probes interactively in the Graphics window, see Using the Point Tool and Using the Line Tool, or set the following properties manually:


Edit [Point/Line] Probe Properties				Point Probe	Line Probe
Snap To Part	Allows you to select a part along which you can position the points (this action is essentially snapping to the bounding box of the part).
Point	Specifies the location of the point. The position vector is specified with respect to the selected Coordinate System.
Point 1 and Point 2	Specifies the location of the line's end points. The position vectors are specified with respect to the selected Coordinate System.
Lock	Allows you to fix the position of any coordinate or any combination of them.
Resolution	Specifies the number of evenly spaced segments along the line. The actual number of points in the probe is one greater than the number of segments.
Coordinate System	Specifies the coordinate system for positioning the points.

The following action is available when you right-click the Derived Data manager node:

New > [Type]: Allows you to create a new point probe or a new line probe. A separate Edit tab opens up that displays the customizable properties of the probe.

Plots

The following properties define the characteristics of a plot:


Plot Properties
Name	Specifies the name of the plot under which it is stored in the tree.
Derived Data Items	Specifies the Derived Data objects from which the data are extracted.
Y-Axis Fields	Specifies the specific scalar field function to be plotted as the data value for the y-axis. See Scalar Field Functions.
X Axis Type	Specifies the type of data to use for the x-axis of the plot. The following options are available: Direction: Plots position information along the axes. Selecting this option activates the Direction property. Scalar: Selects a solution variable to be plotted along the axes. Selecting this option activates the X-Axis Scalar property.
Direction	Since derived data exist in three-dimensional space while each axis of a plot represents only a single dimension, the three-dimensional coordinates of the points being plotted must be reduced to one. This objective is accomplished by specifying a direction vector to which the position of sample locations is projected. The following options are available: X-Axis, Y-Axis, Z-Axis: Project the sample locations to the x-,y-, or z-axis of the global coordinate system. Custom Axis: Specify a Custom Direction vector to which the position of sample locations is projected. For example, in order to plot X coordinates of the selected derived data items, you would specify a direction vector of [1,0,0].
X-Axis Scalar	Specifies the scalar field function to be plotted along the x-axis of the plot. See Scalar Field Functions.

The following action is available when you right-click the Plots manager node:

New: Creates a new plot. A separate Edit tab allows you to set the properties of the plot.

The following specific action is available when you right-click a particular plot:

Open: Displays the plot in the Graphics window or makes it active if it is already open.

Reports

The following properties define the characteristics of a report:


Report Properties
Name	Specifies the name of the report under which it is stored in the tree.
Report Field	Specifies the scalar field function upon which the report is based. See Scalar Field Functions.
Report Items	Specifies the items from which the solution data are extracted. You can chose from QuickParts, QuickPart Surfaces, and Derived Data objects.

The following actions are available when you right-click the Reports manager node

Create Post Report: Creates a new report. A separate Edit tab allows you to set the properties of the report.
Tabulate All: Displays all reports in a spreadsheet-like dialog. See Tabulate.
Export All: Allows you to save all reported data in a .csv file.

The following specific actions are available when you right-click a particular report:

Tabulate

Displays the following properties and quantitative values for the selected report in a spreadsheet-like dialog:


Tabular Data
QP/QPS	Displays the respective report item—a QuickPart,a QuickPart Surface, or a Derived Data item.
Field	Displays the respective report field.
Minimum	Returns the minimum field value within the respective report item.
Maximum	Returns the maximum field value within the respective report item.
Average	For a QuickPart, returns the volume averaged field value computed as: $V o l u m e A v e r a g e \equiv \frac{1}{V} \int ϕ d V = \frac{\sum_{c}^{} ϕ_{c} V_{c}}{\sum_{c}^{} V_{c}}$ where $ϕ_{c}$ is the cell value of the selected scalar field and $V_{c}$ is the cell volume. For a QuickPart Surface, returns the surface averaged field value computes as: $S u r f a c e A v e r a g e \equiv \frac{1}{a} \int ϕ d a = \frac{\sum_{f}^{} ϕ_{f} A_{f}}{\sum_{f}^{} A_{f}}$ where $ϕ_{c}$ is the face value of the selected scalar field and $A_{f}$ is the face area.
Total	Returns the sum field value over the faces of a QuickPart Surface. This quantity is only available for the following report fields: Boundary Heat Transfer Mass Flow Rate

It is possible to tabulate several reports at once by holding down the <Ctrl> key when selecting the objects.

Export

Allows you to save the reported data in a .csv file.
