Another common alternative that’s been around longer is to simply group CAD bodies into a “multibody part” (MBP), which then forces Mechanical to recognize their connectivity and interaction with each other. Users might take advantage of the newer Node Merge option that was released in v16.0 of Workbench (WB) Mechanical. There are several alternative ways to make adjacent bodies interact without using contact. Sometimes, this may be no issue if the region is not of interest, but sometimes it can be an issue. Specifically I’m referring to the use of bonded contact in this article, although other contact behavior types run the same risk.

This resource guide will provide all you need to know about CAD geometry in Mechanical WB. It’s a nature of the beast and a result of the numerical activity taking place as the contact and target elements interact with each other. Seasoned, veteran users know that you run a small risk of stress blips very near a region where contact is defined.
