VecSetDM#

Sets the DM defining the data layout of the vector.

Synopsis#

#include "petscdm.h"          
#include "petscdmlabel.h"     
#include "petscds.h"     
PetscErrorCode VecSetDM(Vec v, DM dm)

Not Collective

Input Parameters#

  • v - The Vec

  • dm - The DM

Notes#

This is rarely used, generally one uses DMGetLocalVector() or DMGetGlobalVector() to create a vector associated with a given DM

This is NOT the same as DMCreateGlobalVector() since it does not change the view methods or perform other customization, but merely sets the DM member.
