Nodeset Manager

This module helps user to group set of nodes, name it and use it in different other modules. It reduces significant time in selection of nodes for different purposes.

What is Node Set?

Node Set is a group of nodes selected by user and associated with a name given by user.

What can be done with a Node Set?

• can be used for masking color plot

• can be used for vector plot

• can be used for XYPlot

• can be masked for hotspot finder

Node Set Manager Panel

Creator Tab

Selection using mouse
Rectangle	Allows user to select nodes by user window
Point	Allows user to select nodes by picking
Polygon	Allows user to select nodes by user polygon
Box	Allows user to select a region by mouse and modify the box dimensions.
Visible Surface	A filter option to ignore hidden nodes.
Get Probe Label Nodes	Selects all visible probed node IDs.
Bound Box	A bound box with given distance is considered at each probe label. All nodes within each box are considered for node set.
Selection using highlighted parts
Selection Parts	User can choose any one of the following options. All nodes Connected element nodes All nodes and connected element nodes. Edge nodes Edge element nodes.
Get Nodes	Gets filtered nodes according to the selected constraint.
Selection using current selected nodes
Replace Current	Clears existing nodes and considers new neighborhood or proximity nodes.
Element	Considers adjacent element instead of adjacent nodes
Get Adjacent Nodes	Appends immediate adjacent nodes of current nodes.
Range	Proximity radius value of Node or element.
Element Proximity	A On/Off flag for Element or nodal proximity.
Get Proximity Nodes	Appends nodes within the proximity range.
From Resut Range…	Pops up result range dialog, user can select scalar result and set range. This function selects all the nodes those scalar result value falls within the user range.
Node set Name	Name of the new node set.
Create	Creates a node set with user defined name and final nodes displayed currently.
Clear	Clears displayed nodes.

Manager Tab

The various fields available in the Manager tab are explained below.

Model	Selects a CAE Model
List Box	Lists all node set names corresponding to the model
Show	Check/Uncheck to show/hide
Node set	Node set name mask for hotspot finder or color plot
Mask Type	Allows user to select mask type. (Inside or Outside or None are the types)
Info	Clicking on ‘…’ pops up nodeset info dialog.
Color Mask	Masking the node sets in contour.
Hotspot Mask	Masking the node sets in finding hotspots.
Show Mask Info	Displays Masking info in CAE Legend.
Probe Mask	Masks probe in the nodeset if enabled.
Show NodeSet Parts Only	Displays parts associated with nodesets. And Hides other parts.
Hide NodeSet Parts	Just hides the parts associated with the nodeset.
Edit	Allows user to edit the nodeset.
Delete	Delete all selected node sets.

Nodeset Info Panel

This panel is invoked when user click on the cell under Info header. This helps users to rename the nodeset, edit the color and add and store user information for the particular nodeset.

Nodeset Name	Allows to edit nodeset name and store.
Color	Allows user to edit the color and save.
User Info	Allows users to add and store information for a particular nodeset.
OK	Closes dialog and apply the modifications to parent dialog.

Types of Color Mask

VCollab provides following types in color masking.

• None - No masking

• No Result - Masking region will be in ‘No Result’ color

• Cull - Masking region will be culled

• Transparent - Masking region will be semi transparent.

Note

Color plot masking is not supported for Elemental result contour.

How to create a Node Set

Selection of Nodes

• Click ‘CAE | NodeSet Manager…’ menu item or just click the icon  , which pops up a dialog.

• Click a mouse selection mode, Rectangle / Point / Polygon.

• Rectangle mode

  • Use left mouse button to drag a window to select nodes.

  • Use right mouse button to drag window to deselect nodes.

    

• Point mode

  • Click with mouse left button a node directly to select it.

  • Click with mouse right button a selected node to deselect it.

• Polygon mode

  • Use left mouse button to start defining a polygon.

  • Click points on screen to build user polygon.

  • Use right mouse button click to close polygon.

    

• Now the selected nodes are displayed in viewer.

• Use ‘Visible Surface’ option to filter hidden nodes in current view.

• Box

  • Use left mouse to click and drag to define a box.

  • Each bound plane can be moved in or out using mouse click and drag.

  • 

  • Click the box button again to select nodes within the box. Box will dissappear and nodes will be highlighted.

  • 

Appending Nodes from selected parts

• Select parts of interest before using this option.

• Use ‘All Nodes’ option to get all nodes from the selected parts.

• Use ‘Connected Element Nodes’ option to get nodes from the elements which connects selected parts and other parts.

• Use ‘All and Connected Element Nodes’ option to get all nodes from selected part and connected element parts.

• Use ‘Edge Nodes’ option to get nodes on the feature edges of selected parts. This depends on feature edge crease angle too.

• Use ‘Edge Element Nodes’ option to get nodes from the elements of which has at least one feature edge.

• Click ‘Get Nodes’ button to append the nodes.

Appending Nodes from probe

• Click ‘Add Probe Labels’ button to include all probed nodes.

• Use ‘Visible Probe Labels’ option to ignore hidden probe label nodes.

Appending or Replacing selection using ‘From Selected Nodes : Neighbourhood’

• Click ‘Get Adjacent Nodes’ button to find adjacent nodes of selected nodes.

• Use Proximity Range to find nodes which falls within a given range of selected nodes.( i.e. Nodal Proximity)

• Click ‘Element Proximity’ to find nodes which falls within a given range of elements (associated with selected nodes).

• Click ‘Get Proximity Nodes’ to append the selection of nodes.

• Enable ‘Replace Current’ option will replace the selection instead of appending.

Clearing the selection

• Click ‘Clear’ button to clear current selection of nodes.

• Repeat the above suggestions to build your selection of nodes again.

Creating Node Set

• Enter an unique name to the selection of nodes in text box given

• Click ‘Create’ button to create node set and name will be added to the list in the manager tab.

How to manage *Node Set* list?

• Make sure that you have created Node Sets already.

• Click ‘CAE | NodeSet Manager…’ menu item, which pops up a dialog.

• Click Manager tab.

• Select CAE model for which node sets are listed.

• Select a node set name.

Editing Node Set

• Click ‘Edit’ option to modify the nodes.

• User can clear and build new node set, Or

• User can filter nodes by removing nodes.

Deleting Node Sets

• Select a Node Set to be removed.

• Click ‘Delete’ button.

Toggling Node Set Attributes

• Click ‘Show’ check box in the Node Set list box to turn On / Off its visibility.

• Select ‘In’ or ‘Out’ opition in Mask drop down to mask the selected nodes or unselected nodes respectively. Select ‘N/A’ option to exclude from masking.

• Click ‘Color’ cell to edit display color of the nodes.

Combination of In and Out masked Nodesets

Nodeset A with In mask type is refered as A

Nodeset A with Out mask type is refered as A’

Node Sets in Hotspot Finder

Note: Masking is not supported for Elemental Result.

• User can select multiple Node Sets and can be masked in hotspot finding operation.

• Open Hotspot Finder Settings

  

• Click “Mask…” button, which pops up a Nodeset Manager dialog to select or deselect Node Sets.

  ‘Inverse’ ON  will exclude the node sets selected, where as ‘Inverse OFF’  finds hotspots only in the node sets selected.
