This command is used to construct a multi-point constraint between nodes.
| equalDOF $rNodeTag $cNodeTag $dof1 $dof2 ... |
| $rNodeTag | integer tag identifying the retained, or master node (rNode) |
| $cNodeTag | integer tag identifying the constrained, or slave node (cNode) |
| $dof1 $dof2 ... | nodal degrees-of-freedom that are constrained at the cNode to be the same as those at the rNode |
| Valid range is from 1 through ndf, the number of nodal degrees-of-freedom. |
EXAMPLE:
equalDOF 2 3 1 3 5;
- impose the displacenebts at dof's 1,3 and 5 of node 3 to be the same as those of node 2.
