Hello,

When applying the Riemann Invariants at subsonic inflow/outflow boundaries, you require the normal velocity and tangential velocity of internal cells or the free-stream. Am I correct in assuming that these quantities are not just the magnitude of those velocities, but that they can have negative signs?

Thank you,
