Dear Deepak, To the best of my knowledge, such functionality is not available in the library because, well, its not the normal type of information that one would be interested in. So you'll have to write the functionality yourself.
What have you tried so far? How I would do it is by computing some information up-front, namely for each FE type (i.e. different combination of bases), determine the number of support points on a cell face. The FE::has_support_on_face <https://www.dealii.org/developer/doxygen/deal.II/classFiniteElement.html#af1043fc052fed945f579317f029ad00a> function could be of use here, or you could locate the physical position of the support points on the face and count the number of unique entries. You could then loop over all cells and their faces, and the number of "hanging" support points on a single face would be the difference between the values you've computed *a priori* for the face between the two cells. You'd have to be careful not to do any double accounting, of course. The tutorials on hp-refinement as well as DG methods may shed some further light on what other tools you may require. I hope that this helps get you started.
