NodalStickConstraint
Sticky nodal constraint for contact
Both kinematic and penalty formulations are implemented.
For the penalty formulation, the contribution to the residual for the constrained nodes on the primary side is equal to
and the opposite on the secondary side, where is usually the displacement component variable value at the node for mechanical contact applications.
commentnote
The primary and secondary variables must be different for this implementation of the nodal stick constraint.
