HM-3430: Part Replacement Through Connectors

A new part is needed in the assembly. In this tutorial you will learn how to delete the original component, import a new part, and update the connections. You will also export the connector information to a single file, and then export the entire FE input deck and observe how the connector information is preserved.

In this tutorial you will learn how to:
  • Replace the rear truss component, Rear_Truss_1, with a new, similar part and then update the affected connectors.
  • Export the connector information
  • export the FE deck and view the connector information in the deck

After the modeling of the assembly is complete, a design change might be made to any one of the parts. When this occurs, you must replace the current part(s) in the model with the new, similar one(s) and update the affected connections (welds).

This exercise uses the file, which can be found in the file. Copy the file(s) from this directory to your working directory.

Open the Model File

In this step you will open and view the model file.

  1. Start HyperMesh Desktop.
  2. In the User Profile dialog, select OptiStruct
  3. Click OK.
  4. Open a model file by clicking File > Open > Model from the menu bar, or by clicking on the Standard toolbar.
  5. In the Open Model dialog, open the file.
    A model appears in the graphics area.
  6. Observe the model using various visualization options available, such as rotation and zooming.

Load the Connector Browser

In this step you will load the Connector Browser.

  1. Open the Connector Browser by clicking View > Browsers > HyperMesh > Connector from the menu bar.
  2. Review the layout of the Connector Browser. Currently there are no components or connectors listed because there are no connectors in the model.
    Note: You can use the Connector Browser to view and manage the connectors in your model. The top portion of the browser is referred to as the Link Entity Browser, and it displays information about the linked entities in your model. The middle portion is referred to as the Connector Entity Browser, and it contains a list of the connectors in your model. The bottom portion of the browser is referred to as the Connector Entity Editor, and it displays attributes assigned to the connector(s) selected in the Connector Entity Browser. HyperMesh groups the connectors based on their connection type.

Realize the Connectors

In this step you will realize the connectors in the component Con_Rear_Truss.

  1. In the Model Browser, Component folder, right-click on Con_Rear_Truss and select Make Current from the context menu.
  2. Open the Spot panel by right-clicking in the Connector Entity Browser and selecting Create > Spot from the context menu.
  3. Go the realize subpanel.
  4. Click connectors >> displayed.
  5. Click type= and select weld.
  6. In the tolerance= field, type 10.
  7. Set the mesh dependent/mesh independent toggle to mesh dependent.
  8. Under mesh dependent, set the adjust realization/adjust mesh toggle to adjust realization.
  9. Click realize.
    The connectors are realized.
  10. Return to the main menu by clicking return.

Save Connector Information

In this step you will save the connector information to an XML file.

  1. At the bottom of the Connector Browser, click (Export connectors -XML).
  2. In the Export to file dialog, navigate to the location where you would like to save the XML file and click Save.
  3. In a text editor, open the XML file.
  4. Inspect the file and observe how the connector information has been saved. In the future, you can use the XML file to import connectors.
