    Node to Node contact is not available as a pure 'Contact'.

    But you can achieve this using CGAP/PGAP.

    I believe there are a few tutorials and the documentation is clear enough.

     

    But essentially you create a gap element, and assign a PGAP property defining u0 (gap aperture) and K0/K1 stiffness for open/close gap.

    In this case you need to perform a NLSTAT loadstep.
