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 pe
