PetscErrorCode DMSetPeriodicity(DM dm, PetscBool per, const PetscReal maxCell[], const PetscReal L[], const DMBoundaryType bd[])

Input Parameters

dm - The DM object
per - Whether the DM is periodic or not. If maxCell is not provided, coordinates need to be localized
maxCell - Over distances greater than this, we can assume a point has crossed over to another sheet, when trying to localize cell coordinates
L - If we assume the mesh is a torus, this is the length of each coordinate
bd - This describes the type of periodicity in each topological dimension
