PETSc version 3.17.0
DMGetCoordinates
Gets a global vector with the coordinates associated with the DM.
Synopsis
#include "petscdm.h"
#include "petscdmlabel.h"
#include "petscds.h"
PetscErrorCode DMGetCoordinates(DM dm, Vec *c)
Collective on dm
Input Parameter
Output Parameter
| c | - global coordinate vector
|
Note
This is a borrowed reference, so the user should NOT destroy this vector. When the DM is
destroyed the array 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...)
