In COMSOL Multiphysics you can model contact between
•
A group of boundaries in 1D, 2D, or 3D by adding a
Contact Pair
and a
Contact
feature
•
A group of geometric objects in 2D or 3D by adding a
General Contact Pair
and a
General Contact
feature
•
Interior boundaries in 2D or 3D by adding
Interior Contact
feature
There are three classes of contact methods available: the
penalty
method, the
augmented Lagrangian
method, and the
Nitsche
method.
General Contact
only supports the
penalty
method.
In this section
pair
collectively refers to the
Contact Pair
and the
General Contact Pair
