Manage Subsystem Representations

Once you have created a subsystem and populated it with content, you can save the representation locally or save a revision to the Subsystem Library.

1. In the Subsystem Browser, right-click on a subsystem(s) and select Representation > Save from the context menu.
   The Save Representation dialog opens. A checkmark in the Available column indicates that the representation already exists in the local repository. A checkmark in the Library column indicates that a revision is already available in the Subsystem Library.
2. Optional: If saving to the Library, edit the Major Revision and Study Revision columns to reflect the intended revisions.
   If no changes are made to the Major or Study revision, then the Library revision will be incremented.
3. Optional: Add a comment to the subsystem.
   Typically, this is done to denote the changes made since the last revision was saved. It was a way of recording the history of changes to the subsystem.
4. Optional: To save parts locally, deactivate the Save to Library checkbox.
   In this case, there is only no revisioning; if a representation is already available, you need to activate Overwrite Available to replace the existing representation with the one you are about to save.
5. Click OK.

Subsystem representations can be added from external sources such as solver decks.

1. In the Subsystem Browser, right-click on a subsystem(s) and select Representations > Add > from Files from the context menu.
2. Give the representation a name.
3. Select the correct file type.
4. Browse to the file that you want to add as a representation and select file path.
5. Click OK.
   You can choose whether this representation is also saved to the library.

   Note: Supported solver decks include: Radioss, OptiStruct, Nastran, Abaqus, PAM-CRASH 2G and LS-DYNA.

Subsystem representations can be added from external sources such as a subsystem library.

1. In the Subsystem Browser, right-click on a subsystem(s) and select Representations > Add > from Library from the context menu.
   The Add Representations from Library dialog opens.
2. In the Add Representation from Library dialog, select the representations to add.
3. Optional: To simultaneously add and load representations, select the representations to load from the Load Added Representations list.
4. Click OK.

Add representations to the library if they are in session.

1. In the Subsystem Browser, right-click on a subsystem(s) and select Representations > Add > to Library from the context menu.
   The Add Representations to Library dialog opens.
2. In the Add Representations to Library dialog, select the representations to add.
3. Click OK.
   The Add Representation to Library dialog displays information regarding the availability of representations in library, session, and overwrite details.
   The image below shows that crash representation data is saved in session but is not saved to the library.

Subsystem representations can be loaded from the current HyperMesh session.

1. In the Subsystem Browser, right-click on a subsystem(s) and select Representations > Load > from Session from the context menu.
   The Load Representation dialog opens.
2. In the Load Representation dialog, Load tab, select a type of representation to load.
   Representations that exist in the repository are shown in the Representations column, and their availability is indicated in the Available column.

Subsystem representations can be loaded from the subsystem library.

1. In the Subsystem Browser, right-click on a subsystem(s) and select Representations > Load > from Library from the context menu.
   The Change Representation dialog opens.
2. In the Change Representation dialog, Library tab, select the appropriate representations.
   The selected representations are loaded into the Representation folder on the file system as well as into the HyperMesh session.

Unload subsystem representations from a session.

1. In the Subsystem Browser, right-click on a subsystem(s) and select Representations > Unload from the context menu.
   The Confirm Unload Representation dialog opens.
2. In the Confirm Unload Representation dialog, click Yes to unload the selected representations.

Subsystem representations can be deleted from the current HyperMesh session.

1. In the Subsystem Browser, right-click on a subsystem(s) and select Representations > Delete > from Session from the context menu.
   The Delete Representations dialog opens.
2. In the Delete Representations dialog, select the representations you want to delete.
3. Activate the Delete representation from library checkbox.
   Note: The Study version will be incremented if a representation is deleted from the Library.
4. Click OK.

Subsystem representations can be deleted from the Part library.

1. In the Subsystem Browser, right-click on a subsystem(s) and select Representations > Delete > from Library from the context menu.
   The Delete Representations from Library dialog opens.
2. In the Delete Representations from Library dialog, selected the representations you want to delete.
3. Click OK.

Use the Library Viewer to review subsystem library content.

1. In the Subsystem Browser, right-click on the part assembly or part(s) and select one of the following:
   • Representations > Add > browse Library
   • Library > Library Viewer
   The Library Viewer opens.
2. Select the subsystem revision that you would like to review.
