Creating Contact Pairs for Structural Contact Modeling with Form Assembly
For any structural contact model in COMSOL Multiphysics®, you should finalize the geometry using Form Assembly and create contact pairs. The pairs can be defined automatically through the Form Assembly operation and/or manually. When using the former option, it is good practice to verify that the pairs created are correctly defined.
To enable structural interaction between the different parts of your model, you will use the Contact Pairs to define Contact boundary conditions in the Solid Mechanics interface. In this demo example, we show how these settings are used to enable contact in a stamping model. For more information on modeling structural contact, check out our Contact Switch model.
