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
