DMGetCoordinatesLocal#

Gets a local vector with the coordinates associated with the DM.

Synopsis#

#include "petscdm.h"          
PetscErrorCode DMGetCoordinatesLocal(DM dm, Vec *c)

Collective on dm the first time it is called

Input Parameter#

  • dm - the DM

Output Parameter#

  • c - coordinate vector

Notes#

This is a borrowed reference, so the user should NOT destroy this vector

Each process has the local and ghost coordinates

For DMDA, in two and three dimensions coordinates are interlaced (x_0,y_0,x_1,y_1,…) and (x_0,y_0,z_0,x_1,y_1,z_1…)
