Hello,
I have a question regarding the member nodal responses in RAFT.
As I understand it, the beam element stiffness matrix is formulated as a 12×12 matrix, which implies 6 DOFs per node for a 2-node beam element. However, when I checked the response stored for the member nodes, it appears that only 3 DOFs are available at each node.
For example, the member information is as follows:
len(memberlist.nodeList) = 13
len(memberlist.r) = 13
m.u.shape = (1, 13, 3, 20)
So although the member has 13 nodes, the response seems to contain only 3 DOFs per node instead of 6.
Could you please clarify this?
Also, where can I access the full 6-DOF nodal response needed for beam internal force or moment calculations?
I would appreciate any clarification. Thank you.
Best regards,
