Creating and Editing an Interference Simulation

• Append Intermediate Representation: to include intermediate representations to the interference computation. When you select this check box, the computation includes the interferences between the following elements of the context:
  • Parts and representations under the same product
  • Representations from the different products under the same simulation context
  Note: Interferences between the representations under the same product are not computed.

  By default, this check box is cleared.

• Compute Between Intermediate Representation: to identify interferences that exist between representations under the same product. This check box is available for selection when the Append Intermediate Representation check box is selected.

• The name of the opened product is displayed in the Context product name box.

  If no product is selected or more than one product is selected, the Context product name box is empty.

  If more than one product are opened in a session, select the product from the list. You can also click to search the required product and select advanced filters pointing to it for computing interference simulation.

• If a filter or an advanced filter is created on the product, it is automatically retrieved and its name is displayed in the Filter box. If more than one filter is created on the product, the filter is not automatically retrieved.

  You can click Add a filter to apply on the root product and select the required filters associated with the context.

• You can add advanced filters as context or in groups.
  • Notes:

    • Advanced filters defined in groups are considered only while computing interferences and not while loading an interference simulation.
    • Interference simulations with advanced filter as context cannot be explored or opened using Navigation Experience.
• If no document is opened or explored and you add the filter while computing interference simulation, only a light panel, Filter Panel is displayed. In this panel, you cannot hide columns. Any customization in the Filter Panel is not persistent.
• If filters are not defined for the context, you can do so as below:

1. Click Add a filter to apply on the root product next to the Filter on the root product box.
2. In the Filter Panel dialog box, from the list of filters applied on the root product, select the required filter.
   In the work area, the complete root product is displayed and the interference simulation is computed only between the filtered parts of a root product.
3. Optional: To remove the filter on the root product, from the Interference Analysis section of the action bar, select Edit specification , and then click Remove the filter applied on the root product in the Context tab.

   You can click Add a filter to apply on the root product to replace the filter applied on the root product.

   Notes:

   • You can open the interference simulation created with the filtered product. To do so, search the interference simulation, right-click the required interference simulation, and then click Open.
   • When you delete the filter on the root product, a complete product is considered while computing the interference simulation.
   • When you edit the filter and remove or add the features, the interference simulation session needs to be updated manually.

     If you remove any instance of the interference simulation, the interferences with that instance become out of scope.

   • When you edit the filter and remove or add the features, and open the interference simulation with Open, the interference simulation session needs to be updated manually.

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.

   You can create several groups within the simulation context and compute the interferences between them.

   Note: You can click Add more groups and select products or parts in the 3D area or the tree to create multiple groups at a time. Each product or part selected is added as a separate group.

3. Add the required elements in the group. To do so:
   • Click Add the selected product in the group to add objects to the selected group. Select the product or the parts in the 3D area or the tree to add them to a new group.
   • Click Remove the selected product from the group to remove selected objects from the selected group. When nothing is selected, all the objects are removed from the group.
   • Click Delete this group to delete the selected group.
   • Click Add the selected filter to this group to add a previously created filter to define the group context.
   For more information about creating filters, see Social and Collaborative Apps: Product Development- Model Based: Product Finder Guide User's Guide: Using Persistent Filters: Creating a Persistent Filter.
   Notes:

   • You can apply filters in all modes except Between all components mode.
   • You can add one filter for a selected group.
   • You can either add a filter or manually select a product for the selected group.
   • If you add a filter again after adding a filter to the group, the filter from the group is replaced with the new filter.
   • For filters, if advanced filters defined in groups point to elements that are not pointed by filter or advanced filter context, interferences cannot be computed.
   • If a part is added to the product structure, which matches the filter criteria, this new part will not be taken into account until the current interference simulation is closed and re-opened.
   • If the context product is changed (only accessible when creation is started from no tab), all groups are deleted.

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

1. Select the following check boxes under Specifications and required results:
   • Clash: to compute clashes only.
   • Contact: to compute clashes and contacts.
   • Clearance: to compute the clearances lower than the minimum clearance value defined in the Clearance box, clashes, and contacts.

   By default, the Clash check box is selected.

2. Optional: Under Applicative Rules, select the following check boxes:
   • Fasteners: Lets you consider the fasteners while computing the interference simulation.

     Select the Check interferences with fastened parts check box check each fastener (primary or secondary) component against the fastened parts. Selecting this check box considers all components of a fastener against all components of another fastener, and a fastener against all the external parts while computing interference simulation.

     Note: The check boxes are displayed only when you have the license of a corresponding fastener role.

     When a product containing fasteners is opened while no license for the fastener role is granted:

     • Newly created interference simulations ignore fasteners.
     • When you update the existing interference simulations computed considering the fastener components, an information message is displayed and the update fails.
   • Pathways detailed into segments: Lets you consider the pathway features defined in the pathway geometry while computing the interference simulation.
     Notes: For considering pathway features while computing the interference simulation, the following conditions must be fulfilled:

     • Set the value of the SYSTEMS_3D_ARCHITECTURE variable to 1.
     • Select the System 3D architecture information to include during the save process check box under Me > Preferences > App Preferences > 3D Modeling → System Architecture > System 3D Architecture > System Space Reservation.
   • Electrical branches detailed into segments: Lets you consider the segment and protection features defined in electrical branch Geometries while computing the interference simulation.

3. Optional: Select the Knowledge rule check box under User-Defined Rules and select the knowledge rule set for interference computation.

   For more information, see Interference Check User's Guide: Defining Interference Simulation Specifications: Creating Interference Simulations Using Knowledge Rules.

4. Optional: Select the Engineering connection check box under User-Defined Rules to define engineering connection specifications.

   For more information, see Interference Check User's Guide: Defining Interference Simulation Specifications: Creating Interference Simulations Using Engineering Connections.

5. Optional: Select the following check boxes under Update Rules to reuse the interference results:
   • Recompute only modified interferences: to reuse existing interference simulation results and compute only the modified interferences while updating the interference simulation.
     Note: Results are reused only while re the same interference simulation.
   • Delete out of scope interferences: to remove the interferences are out of scope. To make this check box available for selection, select the Recompute only modified interferences check box.

6. Optional: Select the following check boxes under Stored Quantifiers to compute the quantifiers and display their values in the Quantifier column of the interference simulation multi-list:
   • Penetration volume: to compute and store the penetration volume when a clash is detected. You can search for an interference simulation using the advanced search, specifying the penetration volume as a search attribute.
   • Penetration vector: to compute and store the penetration vector value when a clash is identified. You can search for an interference simulation using the advanced search, specifying the penetration value as a search attribute.
     Note: When this check box is selected along with the Penetration volume check box, by default, the penetration volume appears in the quantifier column. You can right-click the Quantifier column and select Clash Value > Penetration Vector .
   • Minimum distance: to compute and store the minimum 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
