# 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()`.
