Paras,
You can also use add_periodicity with regular Triangulation objects, see
https://www.dealii.org/current/doxygen/deal.II/classTriangulation.html#adbf04756b28dae69194870812acaf941.
This should make sure that periodic neighbors differ at most by one
refinement.
Best,
Daniel

Dear Wolfgang,
Thank you for the hints. The second approach seems easy to start with.

Paras,
I don't think there is a way that's already implemented, but if you look at
the function that implements the periodic boundary conditions, you should be
able to clone it in your project and add the negative sign where necessary.
Alternatively, you can let the existing function create
Dear dealii Community,
I am working on a solid mechanics related problem involving anti-periodic
constraints, i.e.
u_leftFace = - u_RightFace,
where u is the unknown field (a component of the dim-dimensional
displacement field).
One possible solution, I am aware of, involves marking the
