p6est_comm_parallel_env_replace
void p6est_comm_parallel_env_replace(p6est_t *p6est, sc_MPI_Comm mpicomm)
Replace the current MPI communicator by the one provided as input.
p6est_comm_parallel_env_release
void p6est_comm_parallel_env_release(p6est_t *p6est)
Release MPI communicator if it is owned by p6est.
