I am modelling a hollow tube with shell elements for a stub column test. <\/p>\n

I want to apply the loads\/displacements to a central node at the top instead of to the edge of the tube.<\/p>\n

The central node is the master node, and the nodes at the edge are the slave nodes.<\/p>\n

When solving, I get the error "Specified degree of freedom constraint at unused node". I understand this is because the master node is not attached to any element.<\/p>\n

How can I solve this error? I want the load\/displacement applied to the master node to be transferred to the nodes at the edge of the tube.<\/p>\n
