The ordering of the nodes is given in section 9.3 of the reference 
manual. For second order elements, the first order nodes are given 
first, followed by the nodes associated with the edges, followed by the 
nodes associated with the quadrangular faces (if any), followed by the 
nodes associated with the volume (if any). The ordering of these 
additional nodes follows the ordering of the edges and quadrangular 
faces given in section 9.3.
