DMSetApplicationContext#

Set a user context into a DM object

Synopsis#

#include "petscdm.h"          
#include "petscdmlabel.h"     
#include "petscds.h"     
PetscErrorCode DMSetApplicationContext(DM dm, void *ctx)

Not Collective

Input Parameters#

  • dm - the DM object

  • ctx - the user context

Notes#

A user context is a way to pass problem specific information that is accessible whenever the DM is available In a multilevel solver, the user context is shared by all the DM in the hierarchy; it is thus not advisable to store objects that represent discretized quantities inside the context.
