Computing Interferences in Non-Persistent Mode

You can compute an interference without creating a simulation in an assembly using non-persistent interference simulation.

Important: The result of the non-persistent interference simulation is not saved.

  1. In the Specifications tab, select the required options.
    • Select the required standard specifications.
      • Clash and Contact: to compute clashes and contacts.
      • Clearance: to compute the clearances lower than the minimum clearance value defined in the Clearance box.
    • Select the required engineering connection specifications.
      • Check No Clash: Identifies only clashes
      • Check Contact: Identifies clashes and clearances
      • Check Clearance: Identifies clashes, contacts and clearances with 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.
    • Select the required computation quantifiers.
      • Minimum Distance: to compute and store the minimal clearance distance. The check box is available when you select:
        • The Clearance check box under Standard Specification
        • The Activate and Check Clearance check boxes under Engineering connection specification
        • The Activate check box under Knowledge rules specifications
      • Penetration Vector: to compute and store the penetration vector value when a clash is identified. You can search for an interference simulation using advanced search, specifying the penetration value as a search attribute.
  2. Define the context to compute the interference.

    By default, Between all components is selected which computes the interferences between all the elements under the selected root product.

  3. To define the groups inside the simulation context:
    1. From the list, select either of the following:

      • Inside groups: to compute interferences between the elements of a group. You can select one or more groups. However, interferences are computed only between the objects of the same group.
      • Groups against groups: to compute interferences between the elements of different groups. Interferences are computed between all parts of one group and all parts of other groups.
      • Groups against context: to compute interferences between the selected elements in a group, and the remaining elements in the context. Interferences are computed between defined groups against the context.

    2. Click Add new group to create a group.
    3. Add the required elements in the group. To do so:

      .

  4. Click OK.
  5. Undock the multi-list to see the summary of number of clashes, contacts, and clearances.
  6. Click Close.
    The multi-list closes and the results are not saved in the tree.
