Total Number of Contact Forces Is Very Large

Condition

The number of loads due to motion contacts is greater than 18,000.

Cause 1

There is a large number of individual force vectors due to motion contacts acting on the part.

Remedy

We recommend that you try reducing the overall number of loads by enabling the Use Summed Contact Forces option when you perform part analysis or part optimization with motion loads.

Cause 2

There is a large number of summed force vectors due to motion contacts acting on the part.

Remedy

  • Try limiting the number of forces by enabling the Time Range option in the Run Part Analysis or Run Part Optimization window and restricting the time interval.
  • Alternatively, you can try reducing the Motion Contact > Resolution setting in the Property Editor for the part. This requires rerunning the motion analysis.
  • Another option is to divide your geometry into smaller regions by using the Partition tool, and define the motion contacts using the partitions instead.
  • Review the Best Practices for Motion Contacts topic for additional ideas.
