RigidRod::RigidRod - mismatch in numDOF between constrained

[duttaANURAG]

Good Evening Community,

I was performing wall backfill analysis using rigidLink Bar command. When I performed opensees analysis, I got this -

RigidRod::RigidRod - mismatch in numDOF between constrained Node 1 and Retained node 1001

Can someone please tell me what does this command mean?

Please help me. Your kind help will be appreciated a lot.

Thank You.
