Open the Subsystem Browser

Use the Subsystem Browser to create, organize and manage CAE subsystem level models using any entities.

From the Assembly ribbon, click the Subsystems tool.


Figure 1.
The Subsystem Browser opens.

All of the contents of a subsystem are displayed, as well as all entities.

The Subsystem Browser has a similar layout to the Model Browser. It has a grouped entity folder at the first level with solver-specific sub-types at the second level. You can double-click either the first or second level to invoke a specific entity view. There is also an optional 3rd level to show all entities in the Subsystem Browser itself. To turn on the 3rd level, right-click in Subsystem Browser and select Configure Browser. Check the Show entities under subfolders option and click OK.
Figure 2.

By default, the following attributes are listed as columns.

Add or remove columns by right-clicking on a column and checking/unchecking the appropriate attribute.

Name
Expandable list of subsystems and entities.
ID
Identification number of the subsystem and entities.
Color
Color of the subsystem and entities.
UID
Subsystem and part unique ID.
Revision
The Major, Study, and Library revision of the subsystem and contained parts.
Representation
Loaded representation of the subsystem.
Comment
User-defined comment assigned to the subsystem representation when it is saved.

Entity Editor

Display the attributes for the subsystem if selected. Edits can be made to single subsystem selections only.

Entities

Nodes, elements, loads, systems, vectors, and beam sections are displayed in the Entity Editor. Each of these entities can be selected. This invokes the selection options so that you can add to or remove from the selection, updating the contents of the subsystem.

When there are multiple includes in a subsystem, the default Entity Editor will show ‘All’ include contents, in which case you can not add entities from a selection. You need to select which include the contents will be added to by first selecting the appropriate include from the “Include” option.


Figure 3.

Finally, entities can also be reviewed.

Dependent Entities

Dependent Entities are options for showing contents of the subsystem that may be disorganized. There are four settings:
Off
The default setting. Checking dependent entities reduces the responsiveness of the selection of subsystems in the browser.
Missing
Missing entities occur when the entity is not present in the subsystem but was expected to be there since the parent entity was displayed. For elements and nodes, this occurs when the entity is not in the subsystem but the component is.
Additional
The inverse of Missing. This occurs when the entity is in the subsystem but the parent is not. For example, the node is in the subsystem but the component is not. If all entities are organized into subsystems, an entity that is additional in one subsystem will be missing from another.
Shared
Only nodes can be shared. This occurs when connected elements are organized into different subsystems. In this case, nodes are highlighted that join the two subsystems as shared since those nodes are the shared boundary between two subsystems.

All of the above can be reviewed. You can also Isolate to display the missing entities and then use the Entities option to correct the subsystem by selecting and organizing those missing entities.

Library and Representation Data

Library data shows the Major, Study, and Library revisions of the subsystem. It also shows the Library Name to which the representation was saved. The comment saved along with the representation is displayed here.

Representation data shows the Representation Name and the file path of the saved representation.

Organize Settings

Determine which dependent entities to move when managing subsystem content and behavior if entities are shared across subsystems.

When moving an entity into a subsystem, there are customizable options that determine which dependent entities would also be organized into the subsystem. For example, moving a component by default will also move the associated nodes, elements, properties and materials.

There are secondary options that determine the action if the entity is shared (has multiple references). For example, when moving a property, should the material also move to the subsystem if a different property also references the same material.

When moving an include, organize settings are ignored, and only the include content is moved.

To access these settings, right-click in the Subsystem Browser and select Organize Settings from the context menu.
