Variable Documentation

walberla_mpi_cart_comm_observer

std::shared_ptr<int> walberla_mpi_cart_comm_observer

static

waLBerla MPI Cartesian communicator observer.

It is purposefully decoupled from walberla_mpi_comm. We are not tracking the lifetime of walberla_mpi_comm itself, but the lifetime of its ownership by the waLBerla MPI singleton.
