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???
Attention, defining a contact with friction between two surfaces and joining two surfaces are two very different idealizations in a model.
The best way is to create a Simulation Object (find it in the Simulation toolbar) to define a contact or a gluing. But if you prefer manual modeling in NX Nastran :
- you can define gap and friction elements with a CGAP entry,
- you can define gluing to rigidly connect several grid points together with a RBE2 element.
Hope that it's clear.
