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
dmdmTo - 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 defintion of compatibility of DMs, see DMGetCompatibility().
