DMGetPeriodicity

Get the description of mesh periodicity

Synopsis

#include "petscdm.h"          
PetscErrorCode DMGetPeriodicity(DM dm, const PetscReal *maxCell[], const PetscReal *Lstart[], const PetscReal *L[])

Input Parameter

• dm - The DM object

Output Parameters

• maxCell - Over distances greater than this, we can assume a point has crossed over to another sheet, when trying to localize cell coordinates

• Lstart - If we assume the mesh is a torus, this is the start of each coordinate, or NULL for 0.0

• L - If we assume the mesh is a torus, this is the length of each coordinate, otherwise it is < 0.0
