Rakes List

On the left-most side of the panel is the Rakes list. The Streamlines status is also shown in this listing. When streamlines have been created from a rake, the Streamlines status changes from N/A to Available.

After streamlines have been created, deactivating the check box next to the rake will hide the streamlines group in the graphics area. The same Show/Hide functionality can also be accessed by right-clicking any rake item (see below for additional information on Show/Hide).

You can sort the items in the Rakes list by clicking the Rakes or Streamlines headings.

Add

Adds a new rake to the list. The newly added rake is automatically labeled and is added to the bottom of the list. To change the name of a rake, right-click the current name, enter a new name into the Rename dialog and click OK.

Delete

Deletes the selected Rake/Streamline pair(s) from the list.

Delete

Deletes the selected Rake/Streamline pair(s) from the list.

Rename

Displays the Rename dialog, which allows you to rename the selected Rake.

Show

Displays the selected Rake/Streamline pair(s) in the graphics area and activates the corresponding check box(es).

Hide

Hides the selected Rake/Streamline pair(s) in the graphics area and deactivates the corresponding check box(es).

Show Manipulator

Displays the graphical manipulator in the graphics area for the currently selected rake/streamline. The Streamlines graphical manipulators allow you to modify the location and shape of the rake interactively by scaling, translating, or rotating the line, plane, or area using a manipulator specific to the rake type (Line, Plane, or Area). 

The graphical manipulator is linked to the entity display, therefore if a streamline rake is not displayed, the display of the graphical manipulator is also turned off.

Hide Manipulator

Hides the graphical manipulator for the currently selected rake/streamline in the graphics area.

Rake Type

Allows you to select the rake type for the active (selected) rake:

Line

Rake defined by two end points (the definition of end points is described below).

Plane

Rake is defined by three points (N1, N2, N3) or by a cross section. 

Area

Rake defined by the surface/area of a component collector.

Entity selector

The entity selector allows you to select, or change, the two end nodes or entities which will be used to define the rake.

N1, N2

If a Line rake type is selected: the node/vector entity selector (N1, N2) and the Select by ID dialog can be used to select your desired nodes. HyperView will automatically provide the X, Y, Z positions (coordinates) of the nodes at the time of definition. However, the simplest method for selecting nodes is simply by clicking the desired nodes in the graphics area. Alternatively, if you know the specific coordinates of the end points defining the rake, you can simply enter them in the X, Y, Z coordinate text boxes.

N1, N2, N3

If a Plane rake type is selected: the node/vector entity selector (N1, N2, N3) and the Select by ID dialog can be used to select your desired nodes.  HyperView will automatically provide the X, Y, Z positions (coordinates) of the nodes at the time of definition. However, the simplest method for selecting nodes is simply by clicking the desired nodes in the graphics area. Alternatively, if you know the specific coordinates of the end points defining the rake, you can simply enter them in the X, Y, Z coordinate text boxes.

Section

If a Plane rake type is selected: the Section entity selector and the Select by ID dialog can be used to select your desired section.

Component

If an Area rake type is selected: the entity selector (Component) and the Select by ID dialog can be used to specify your desired 2D part/component. However, the easiest way to select a component is simply by clicking the desired component in the graphics area or in the Model browser.

Integration mode

Allows you to select the integration mode for a rake:

Downstream

Integration is done following the velocity field direction.

Upstream

Integration is done upstream, or opposite, to the velocity field direction.

Both

Integration is done both downstream and upstream.

Evenly distributed

Activating this option allows you to evenly distribute the seeds in an Area rake or Plane rake by specifying the number of rows and columns of seeds in a local system.

Number of rows/Number of columns

Allows you to specify the number of rows and columns of seeds for an Area rake or Plane rake.

Number of Seeds

Allows you to specify the number of seeds in a Line rake.

Or

Allows you to specify the number of seeds in an Area rake (distributed on the surface of the 2D part/component), provided the Evenly distributed checkbox is not activated.

Source

Select the vector field to be used for streamline creation from all of the available nodal or elemental vector results (typically the velocity field).

Advanced

See the Advanced Options dialog topic for a thorough description of this dialog.

Delete Streamlines

Deletes any existing streamlines for the selected rakes from the model.

Create Streamlines

Creates streamlines with the specified data for the selected rakes.

Auto-generate streamlines

Activate this option to automatically generate streamlines (if the rake remains at least partly in the fluid domain and the stream lines existed prior to changing the rake).

If the streamline is contoured prior to changing the rake, the contour will be automatically regenerated also.

Draw as tube

Draws the streamlines as tubes instead of lines. The streamlines will appear to have a larger diameter (for the same streamline size) when the Draw as tube option is activated.

Auto-color streamlines

Activate this option to use the number specified in the Number of colors text box to distinguish streamlines.

Number of colors

Number of distinct colors to use when the Auto-color streamlines option is activated.

Streamline size

Relative scale for the streamline thickness.

Seed marker size

Allows you to specify the size of the seed nodes which are being used as the starting point for the streamline generation.
