DMDAVecGetArrayDOF#

Returns a multiple dimension array that shares data with the underlying vector and is indexed using the global dimensions.

Synopsis#

#include "petscdmda.h"   
PetscErrorCode DMDAVecGetArrayDOF(DM da, Vec vec, void *array)

Logically collective

Input Parameters#

Output Parameter#

  • array - the array

Notes#

Call DMDAVecRestoreArrayDOF() once you have finished accessing the vector entries.

In C, the indexing is “backwards” from what expects: array[k][j][i][DOF] NOT array[i][j][k][DOF]!

In Fortran 90 you do not need a version of DMDAVecRestoreArrayDOF() just use DMDAVecRestoreArrayF90() and declare your array with one higher dimension, see src/dm/tutorials/ex11f90.F
