DMStagMigrateVec#

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

Synopsis#

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().
