Grouping Components in Contact

For Motion Analysis studies, when your assembly includes components that make contact during motion, you can create two groups of components to analyze component contact across the groups and ignore contact among components within the groups. A contact group is treated as a single component in contact force calculations.

1. From a Motion Analysis study, click Contact .

2. In the PropertyManager, under Contact Type, click Solid Bodies .

3. Under Selections, click Use contact groups.

   The two group component selection fields appear.

4. Select components for each contact group:
   • Click the selection field for the first group and select its components from the FeatureManager or the graphics area.
   • Click the selection field for the second group and select its components.

   

   

   The colors of selected components in the graphics area match the selection field color.

   

   The number of contact pairs across the two groups is displayed in the PropertyManager. The number of contact pairs is the product of the number of components in each group. The more contact pairs that appear, the longer the motion computation.

5. Select other contact options and click to close the PropertyManager, or click Keep Visible before clicking to define more contact objects.
