Sambit, your minimal example fails, because you are calling GridTools::collect_periodic_faces(triangulation, /*b_id1*/ 2*i+1, /*b_id2*/ 2*i+2,/*direction*/ i, periodicity_vector); after triangulation.refine_global(2); again. As explained in the documentation <https://www.dealii.org/8.5.1/doxygen/deal.II/namespaceGridTools.html#aaeadfc0053429f542fbfd48d192b94f0> this is not unexpected.
Does your issue pertain after making sure to call GridTools::collect_periodic_faces(triangulation, /*b_id1*/ 2*i+1, /*b_id2*/ 2*i+2,/*direction*/ i, periodicity_vector); only before mesh refinement?
