Check connections

Checking connections allows you to identify and group all connections and connected components or meshes in your model. Additionally, you can validate universal connections by setting and checking tolerances.

1. Depending on what you want to find, make the Simulation file or the FEM file the displayed part.To find contact and gluing connections, such as Surface-to-Surface Contact or Surface-to-Surface Gluing simulation objects, in addition to universal connections, groups of connected meshes, and groups of connected components, make the Simulation file the work part and the displayed part.To find universal connections, groups of connected meshes, and groups of connected components, make the FEM file the work part and the displayed part.

2. From the Resource bar, click the HD3D Tools tab, and double-click Quality Audit .

3. In the Actions group, select the type of check that you want to apply to your model.To find all connections, select the Global Audit Actions check box. You can then limit the types of actions by selecting or clearing the appropriate check boxes.To check universal connections on the object (geometry) level and mesh level, select the Connection Actions check box. You can then limit the types of checks by selecting or clearing the appropriate check boxes.For more information on the types of connection checks, see Connection actions.

4. (Optional) If you selected Connection Actions and you want to override the tolerances that are set in the Customer Defaults dialog box, do the following:Right-click a connection action and choose Settings.In the dialog box, from the Connection Types list, select a connection type.GENERAL specifies that the override will apply to all of the connection types in the Connection Types list except for those that already have an override value. Note: Even though the value you enter for GENERAL applies to all connection types except for those with existing overrides, the original value still appears when you select another connection. indicates that the connection type is using an override value. indicates that the connection type is using the customer default values.Type the override values, and click OK.

5. If you selected Connection Actions, in the Input group, select the component FEM files and connections to which you want to apply the checks by selecting or clearing the appropriate check boxes.

6. To start the checks, in the Controls group, click Start Actions on Selected Input .The Controls group displays the number of checks to be performed.Information for the global checks and errors for the connection checks appear in the Results group.

7. In the Results group, do any of the following to learn more about each connection:Right-click an entity and choose Fit Group in View, Fit Component in View, or Fit Connection in View.Right-click a connection error and choose Zoom to Problem to zoom in to the problematic part of the connection.Hover over an error to view details.Note: To export results, right-click the folder or individual action for which you want the results, and choose Export results.

8. To fix an error, do one or both of the following depending on the connection and the type of error:To open a dialog box where you can update flanges, locations, targets, tolerances, and so on, right-click the connection error and choose Edit.Note: If more than one connection is involved, the other connections are available in the right-click menu. For example if two damper connections are too close to each other, the menu displays both damper connections so you can choose which one to edit.To fix the location or target, right-click the connection error and choose Edit location.Depending on the type of location, a dialog box opens where you can change a node location, a series of nodes, location coordinates, and so on.

9. To visually indicate in the results list that you want to skip some connections while you are fixing other connections, in the Result Type column, click in the Error cell and select Accepted Error. This status is a temporary indicator that you are correcting other connections and are skipping this one while you work on those. When you next run the connection check, the Accepted Error status reverts to Error unless fixing another connection solved the problem.

10. To update the results after you fix an error, do one of the following:To run one action, right-click it and choose Run Action Again.To run all actions, in the Controls group, click Start Actions on Selected Input .Note: Fixing one error can potentially introduce other errors, so running a complete global audit and connection actions check is recommended as you fix errors.

11. To retain your selections and settings so you can use them again for this or a similar model, see Reuse your settings for connection checks.

12. To quit the Quality Audit tool, click Deactivate .
