DMStagMigrateVec

transfer a vector associated with a DMSTAG to a vector associated with a compatible DMSTAG

Synopsis

#include "petscdmstag.h"   
#include "petscdmproduct.h"   
PetscErrorCode DMStagMigrateVec(DM dm, Vec vec, DM dmTo, Vec vecTo)

Collective

Input Parameters

• dm - the source DMSTAG object

• vec - the source vector, compatible with dm

• dmTo - the compatible destination DMSTAG object

• vecTo - the destination vector, compatible with dmTo

Notes

Extra dof are ignored, and unfilled dof are zeroed. Currently only implemented to migrate global vectors to global vectors. For the definition of compatibility of DMs, see DMGetCompatibility().
