Hi Daniel, I still have a question about how to apply periodic boundary conditons: Is there any possibility now to apply PBC with a value 1.0 in x_component and y_component while -1.0 in z_component? I've read an older version of step-45 before (like 8.3.0), which showed we could change that

Hello Daniel, I think i've found where the problem was. It's because I used set_boundary_id with active_cell_iterator after global_refinement. But I found in source codes of collect_periodic_faces function it's just cell_iterator that has been used. I've instead called set_boundary_id at
