Contact types in COMSOL

Hi,
I have recently switched from ANSYS to COMSOL, and I faced some questions regarding the different types of contacts in COMSOL.
Does any one know how to create a No Separation contact between two surfaces in COMSOL?
The two surfaces are not allowed to separate but they are allowed to slide a little bit (a very limited relative motion is allowed in between them).
I really appreciate your help.
Thanks,
Sam

Hi,
The operation you want to do is not considered as a contact condition in COMSOL Multiphysics.
You can use an extrusion coupling to map some of the displacement components on one boundary to another boundary. The two sides do not need to have matching meshes.
An example of this technique can be found in the example deep_excavation in the Model Library/Application Library. Here is a link to the example: www.comsol.com/model/deep-excavation-9747
