Validating Positions Automatically

This task shows how to detect clashes automatically within a simulation.
Open the AUTO_CLASH_DETECTION.CATProduct document.
  1. Double-click Simulation.1 in the specification tree.

    The Edit Simulation dialog box and the Manipulation toolbar appear.
  2. Select the arrow within the Clash Detection from the DMU Check toolbar.

      You may need to undock the toolbar.  When you do, the toolbar looks like this:
     

    Clash Mode toolbar

      Three modes are available:
    • : Off (default mode), which deactivates clash detection
    • : On, which highlights in the geometry area products in collision while playing a simulation
    • : Stop, which stops the simulation when the first clash is detected.  The products are highlighted in the geometry area.

    For Default Clash Detection

    This step can already be validated by a static clash analysis.

    • In Tools > Options > Digital Mockup > DMU Fitting > DMU Fitting tab, if the Activated only while moving check box is selected, no calculation for the first step is performed when the default clash detection is activated (i.e., in On or Stop mode). When running tracks, sequences, or simulations, clashes are still calculated with respect to the default clash detection state (Off, On, or Stop). See Customizing DMU Fitting.
    • By default, this option is not checked.
  3. Click Clash Detection (On) .  

  4. Replay your simulation; select 0.04 (interpolation steps) from the list .

     
    The product in clash with the shuttle is highlighted in the geometry area.
  5. In Tools > Options > Digital Mockup > DMU Fitting > DMU Manipulation tab, select the Clash Beep check box.

      See DMU Manipulation.
  6. Click Clash Detection (Stop) .

  7. Run your simulation.

     This time, the simulation stops at the first clash detected.
