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 periodic faces by means of boundary-ids, traversing through the dofs for each periodic face-pair in order to determine the periodic dof pair and then manually add the entry in the constraint matrix. This approach also worked for cases involving periodic constraints with offsets. I would like to know if there exists a simpler way of achieving the aforementioned goal by a simpler approach, probably by passing some appropriate parameters to the make_periodicity_constraints() function, since we just have a sign change here.
