To what are you referring when you say "outer elements that are created based on the NIP command"? NIP is the number of through-thickness integration points for each shell element. When an element is deleted, any nodes that are freed up will generally remain in the simulation as unattached nodes. Those unattached, free nodes will no longer participate in the contact unless the variable ENMASS in *CONTROL_CONTACT is invoked. See description of ENMASS in the User's Manual.
