# DMSetPeriodicity

Set the description of mesh periodicity

### Synopsis

    #include "petscdm.h"
    #include "petscdmlabel.h"
    PetscErrorCode DMSetPeriodicity(DM dm, const PetscReal maxCell[], const PetscReal L[], const DMBoundaryType bd[])

### Input Parameters

| dm | - The DM object
| 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
