Realize (mesh) universal connections

After creating a universal connection, you must create the connection elements (that is, realize or mesh the connections) before solving the model. You can:

• Create the connection elements in a batch. Use this method when you need to generate elements for a large number of different types of connections at one time.

• Create the connection elements individually. Use this method when individual connections have different tolerances or physical parameters from those set in customer defaults, and for connections such as bolt or seam weld that require you to define additional options prior to meshing.

Create connection elements in a batch

1. (Optional) Set the customer defaults settings for the tolerance and physical parameters so that you can create a large number of connections that use the same settings.

2. Choose Home tab→Universal Connections group→More→Automatic Elements.

3. In the Automatic Connection Elements dialog box, select the type of elements that you want to use to mesh each connection.

4. Click OK.

Create the connection elements individually

1. Choose Home tab→Universal Connections group→More→Connection Elements.

2. In the Connection Element Manager dialog box, in the Create Element group, from the Type list, select the connection type for which you want to create elements and click Add.The corresponding connection element dialog box appears.

3. In the Connection group, identify the connection you want to model in one of the following ways:Select existing connections from:Universal Connections container in the Simulation Navigator.Graphics window.Create a new connection by clicking Create new connection.

4. From the Type list, select the type of elements that you want to use to mesh the connection.

5. Define remaining element properties as needed.

6. Click OK to define the mesh.

7. Click Close to exit the Connection Element Manager dialog box.

Universal kinematic connection elements

After you realize (mesh) a universal kinematic connection, you need to perform the following steps before solving the model:

1. With the Simulation file as the work part and displayed part, choose Home tab→Loads and Conditions group→Constraint Type→Manual Coupling.

2. In the Manual Coupling dialog box, select Multi MPC from the list.

3. In the Elements group, click Select Object and select the corresponding kinematic connection elements.

4. Click OK.

Edit a universal connection element

1. Choose Home tab→Universal Connections group→More→Connection Elements.

2. In the Connection Element Manager dialog box, in the Element List group, select the connection element and click Edit .Note: After editing a universal connection element using the DOF Dependence Check command, the mesh is locked to prevent overriding the edits you made.If you want to override the edits you made, you can unlock the mesh by right-clicking in the Simulation Navigator and choosing Unlock .

3. In the corresponding connection element dialog box, make the necessary changes.

4. Click OK.
