I need to know if contact modeling in COMSOL (by using either the penalty or the lagrangian method)
is based on node-to-node or surface-to-surface contact, because it profoundly affects
the penetration of the contact pairs and the accuracy of the simulation.

Hi,
The formulation is distributed, so I presume that is what you mean by a surface-to-surface formulation. The equations are formed by a numerical integration over the destination boundary, so effectively the gap distance is measured from the Gauss points on the destination boundary.

Henrik
