Hi,
I wnated to know if I can replce glue contact with a RB2 (node to node), CGAP (node to node ) or simply by doing a node equivalence between two surfaces.

Would it make a difference???
Thanks.

Hello,

yes, you can.
Yes, it makes.

Does it help? [dazed]

Why don't you better open at least QRG and check the differences between these elements and their abilities?
It's hard to help you without basic info - what solver / analysis, expectation, purpose of simulation...
 
To add on janFEA's point the Nastran Element Library Reference will have some more info on RBE2/RBE3 elements(7.5 & 7.6) and Gap elements (6.5). You can access the QRG and Element Library Reference through the FEMAP command Help > NX Nastran.
