I have found answer from Generation of Structural elements - #5 by FLAC3D_GEO
Is there any way to share node for different element ids? except for creating node to node link by using “structure node join …”
If I use command “structure node join”, how many links(node to node, node to zone) can exist for one structural node?
Additional question,
1. Please tell me the meaning of warning message below
“Axial direction of cable and piles or normal direction of liners and geogrids at shared node XX out of alignment by more than 30 degrees.”
2. How can I plot nodes before creating structural elements?
model new
structure node create (0.0, 0.0, 0.0)
structure node create (0.0, 0.0, 1.0)
structure node create (0.0, 0.0, -1.0)
structure beam create by-nodeids 1 2 id 1 ; snap on
structure beam create by-nodeids 1 3 id 1 ; snap on
