Issues with Inlet Wall Vectors in Fluent Simulation

Hi everyone,

I'm attempting to use a fully developed pipe flow profile from one simulation as the inlet condition for a nozzle simulation in Fluent. It seems to work quite well overall, but I'm encountering an issue with the vectors at the inlet wall, as shown in the attached image. The vectors are pointing in the wrong direction, and I'm struggling to identify the cause.

Does anyone have any ideas on what might be causing this and how I can fix it?

Thank you in advance for your help!
