Creating Interference Simulations using Engineering Connections

You can create an interference simulation using an engineering connection as a specification. This also optimizes the interference simulation by avoiding the computation of defined unwanted interferences.

This task shows you how to:

Before you begin: Open a product that contains an interference.

Define Check Specification

You can define the check specifications for the engineering connections.

  1. Double-click the defined constraint in the tree.
    The Engineering Connection Definition dialog box appears.
  2. In the Interferences tab, select among the following check specifications:

    • Default: Uses default check specification and generates the result with actual interferences by default.
    • Check: Sets the defined specification (clash, clearance or contact) for the interference and displays the result accordingly after computation. For example, if you set Contact for the interference having Clash and compute the interference simulation selecting the Check Contact check box, results do not include that interference.
    • No check: Computes the interference simulation without considering the respective interferences.
    Based on the check specification, the interferences are checked during simulation.

    Repeat this operation for all engineering connections and specify the required interference types to check during interference simulation.

Create an Interference Simulation

You can create an interference simulation using the interference specification defined in the Engineering Connection Definition dialog box.

Before you begin: Open a product that contains an interference.
  1. Select the required product in the tree.
  2. Click Create Interference Simulation .
    The Interference simulation dialog box appears.
  3. In the Interference simulation tab, type a unique name for the interference simulation. If required, type a description.
  4. In the Context tab, select the context or create groups for the interference simulation.

    For more information about grouping options, see Interference Simulation Definition Dialog Box.

  5. In the Specifications tab, specify the interference simulation specifications.
  6. Select the Activate check box under Engineering connection specification, and select the required specifications.
    • Check No Clash: Identifies only clashes
    • Check Contact: Identifies clashes and clearances
    • Check Clearance: Identifies clashes, contacts, and clearances with a distance less than the specified minimum value of the clearance
    • No Check: Avoids computation for the interferences with specifications set as No Check in the Engineering Connection Definition dialog box.

    Note: If you define both, the standard and the engineering connection specifications:
    • The simulation is computed based on the engineering connections specified for the applicable elements under the context.
    • The simulation is computed based on the standard specifications for the remaining elements under the context.

  7. In the Specifications tab under Options, select the Launch computation now check box to launch the computation when you click OK.

    By default, this check box is selected.

  8. Click OK.

The interference simulation is computed and the results are displayed in the tree.

Create Non-persistent Interference Simulation

You can create a non-persistent interference simulation using the interference specifications defined in the Engineering Connection Definition dialog box.

  1. Select the required product in the tree.
  2. From the Assembly section of the action bar, click Create non-persistent interference Simulation .
    The Light Interference Simulation Definition dialog box appears. It displays the Specifications tab.
  3. In the Specifications tab, specify the interference simulation specifications.
  4. Select the Activate check box under Engineering connection specification, and select the required specifications.
    • Check No Clash: Identifies only clashes
    • Check Contact: Identifies clashes and clearances
    • Check Clearance: Identifies clashes, contacts, and clearances with a distance less than the specified minimum value of the clearance
    • No Check: Avoids computation for the interferences with specifications set as No Check in the Engineering Connection Definition dialog box.

    Note: If you define both, the standard and the engineering connection specifications:
    • The simulation is computed based on the engineering connections specified for the applicable elements under the context.
    • The simulation is computed based on the standard specifications for the remaining elements under the context.

  5. Click OK to compute the interference between all components under the simulation context.

    You can also define groups under the context. See Computing Interferences in Non-Persistent Mode.

    The interference is computed and the results appear in the multi-list.
