This won't help: as soon as the streamline "touches" the boundary
ParaView/VTK assumes that it has left the system (which makes perfect
sense for "outlets"). ParaView/VTK must have some information about
the topology of the problem (which is the opposite side at which the
streamline will "come back in").
