Rajat, Since you are using p4est and PETSc, I suspect that you want to run with more than one MPI process. If you are using a parallel::distributed::Triangulation you will probably run into trouble when the pair of degrees of freedom you want to identify are not known by the same process. You might want to have a look into https://groups.google.com/d/topic/dealii/aX41KqrWE1g/discussion for how you can deal wit this situation by sending the required dofs to the respective MPI processes.
