I'm not sure what you mean by this, but being able to handle periodic domains is important for me. However periodicity is handled there needs to be a way to get access to the correct coordinates for the edge vertices of elements on both sides of the periodic edge so cell volumes/Jacobians can be computed correctly. I don't know why an aliasing array is necessary, since I thought for a topologically periodic mesh *DMPlexConstructGhostCells* should handle this correctly?
