DAVecGetArrayDOF

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

Synopsis

#include "petscda.h"   
PetscErrorCode PETSCDM_DLLEXPORT DAVecGetArrayDOF(DA da,Vec vec,void *array)
Not Collective

Input Parameter

da - the distributed array
vec - the vector, either a vector the same size as one obtained with DACreateGlobalVector() or DACreateLocalVector()

Output Parameter

array -the array

Notes

Call DAVecRestoreArrayDOF() 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]!

Keywords

distributed array, get, corners, nodes, local indices, coordinates
