DMGetCoordinates#

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

Synopsis#

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

Collective

Input Parameter#

  • dm - the DM

Output Parameter#

  • c - global coordinate vector

Notes#

This is a borrowed reference, so the user should NOT destroy this vector. When the DM is destroyed c will no longer be valid.

Each process has only the locally-owned portion of the global coordinates (does NOT have the 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…)
