Connecting two surfaces on FEMAP using NEI NASTRAN

[UTHorn1374]

I was wondering if someone could guide me in the right direction. My issue is that I am trying to model a pipe with a damping wrap around it. My method to try and model this scenario has been to create the pipe and directly on top of it the layer of wrap. I am creating the two using plate elements with identical mesh sizes and mesh orientations. However, I am trying to connect the two to act together, thus leading me to try the glued connection feature on NEI NASTRAN. However, it does not give me any way to define the properties or enter any at all. I am assuming it is using default properties, yet I am not quite sure what they are or where to find them. Also, I would like to check whether or not they are connected considering I'm not looking at the stresses. Is there any way to know that without using the stresses. Also, Is this the best method to use to connect to surfaces together with similar meshes. It would be ideal considering I am going to glue the two in my physical testing, yet I would like to know the properties that NEI NAstran uses.

1) there is a FeMap forum (under Engineering Computer Programs) ... you'll get good help there.

2) i know there are fancier ways, but a simple (and tedious) one would be to put zero length springs (CBUSH) between the two sets of elements. this is easier if both sets of nodes are offset by a fixed amount, like the nodes on one surface are 1 to 999 and on the other 1001 to 1999 and nodes 1 and 1001 are co-incident.
