Dear Lisa, You should have a look at some of the previous discussions on the use of the cell->vertex_dof_index <https://groups.google.com/forum/#!searchin/dealii/vertex_dof_index%7Csort:relevance> function (as well as its documentation <https://www.dealii.org/developer/doxygen/deal.II/classDoFAccessor.html#a5560151b5407e4851d5c1009c7753764>); this provides an easy link between vertices and degrees of freedom.
