Dear Dr. Arndt, I am using the GridTools::collect_periodic_faces(..) as a sanity check after moving the triangulation. I donot again set periodicity constraints. The documentation also mentions "it is possible to call this function several times with different boundary ids to generate a vector with all periodic pairs". Moreover, in my actual application I never do refinement as I read a pre-generated mesh file, where the similar error occurs after moving the triangulation.
I did two more checks in the minimal example- 1) by not calling GridTools::collect_periodic_faces(..) after refinement, I do not get any error messages. But is there a way to check whether the periodic match still holds in the moved triangulation without calling GridTools::collect_periodic_faces(..)? 2) by placing the GridTools::collect_periodic_faces(..) before moving the triangulation but after refinement, it worked fine on serial and parallel, which suggests something breaking after movement.
