DMSwarmMigrate#

Relocates points defined in the DMSWARM to other MPI-ranks

Synopsis#

#include "petscdmswarm.h"   
PetscErrorCode DMSwarmMigrate(DM dm, PetscBool remove_sent_points)

Collective

Input Parameters#

dm - the DMSWARM
remove_sent_points - flag indicating if sent points should be removed from the current MPI-rank

Notes#

The DM will be modified to accommodate received points. If remove_sent_points is PETSC_TRUE, any points that were sent will be removed from the DM. Different styles of migration are supported. See DMSwarmSetMigrateType().
