Occasionally you may wish to connect a line to some other component, such as another line, or perhaps an element which has been created explicitly (in terms of its end nodes, or as part of a cable definition). A useful feature in this context is that of equivalent nodes (as previously described in Equivalent Nodes). This allows you to specify that two individual nodes, which have been previously defined, are in fact the same node from the point of view of the finite element discretisation. If you are working with explicitly defined nodes, you reference the actual node numbers when defining nodal equivalences. If you are utilising the line facility to create your model, you can refer to the relevant node labels rather than node numbers, and define nodal equivalences in the normal fashion.
