PetscErrorCode DMGetPeriodicity(DM dm, PetscBool *per, const PetscReal **maxCell, const PetscReal **L, const DMBoundaryType **bd)

Input Parameters

dm -The DM object

Output Parameters

per - Whether the DM is periodic or not
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
