DMForestSetAdaptivityForest#
During the pre-setup phase, set the forest from which the current forest will be adapted (e.g., the current forest will be refined/coarsened/repartitioned from it) in DMSetUp().

PetscErrorCode DMForestSetAdaptivityForest(DM dm, DM adapt)
Logically Collective
Input Parameters#
dm - the new forest, which will be constructed from adapt
adapt - the old forest
Note#
Usually not needed by users directly, DMForestTemplate() constructs a new forest to be
adapted from an old forest and calls this routine.
This can be called after setup with adapt = NULL, which will clear all internal data
related to the adaptivity forest from dm. This way, repeatedly adapting does not leave
stale DM objects in memory.
