Contact settings describes the interaction between part boundaries that are initially contacting or come into contact during loading. The contact functionality is available in assembly and multi-body part documents. Contact is available for static, frequency, buckling, thermal, nonlinear, dynamic and drop test studies. The Connections icon 
appears above the Fixtures icon 
in the Simulation study tree. Any change in contact conditions requires re-meshing of the model. If you run the study, the software re-meshes automatically.
The right-mouse menu for the Connections icon provides the following contact options:
- Contact Set
- Component Contact
