ID in print command output

[giorgioirotina]

Hi, when I save the results of a particular node with the print command I get

Node: 1
Coordinates : 0 0 0
Disps: 0 0 0 0 3.14719e-008 0
unbalanced Load: 0 0 0 0 0 0
reaction: 0 0 0.129525 44.5344 -8.1446e-013 0
ID : 1090 -1 -1 -1 1091 -1

could you tell me what ID stands for?

It's the internal equation number for each DOF. -1 indicates a constrained DOF.
