do I need to specify the flow direction at a Pressure-Farfield. In my simulation I use a Pressure-Farfield both as an inlet and as an outlet to the domain. So do I need to specify the flow direction, like an axial component of 1 for the inlet and an axial component of -1 for the outlet? This would correspond to the sign assignment for incoming and outgoing mass flows.
Tank you und best reagrds!

Yes: that is required.

Thank you for your response. I tried it with the specification of the flow direction, but now my simulation isn't converging anymore and the outlet massflow is positive. I also saw tutorials on YouTube where they simulated an airfoil and used Pressure-Farfield as the boundary conditions. However, they didn't specify the flow direction but their simulation converged.

Have you looked at the various NACA tutorials to see what's different to your set up? By default the flow is assumed in the +x direction, so it will be set just not highlighted.
