Airflow in wrong direction?

Hi, I have just finished my external aerodynamic simulation for my plane and the air does not look like it is flowing in the right way. could you please help me fix this bug and tell me what is going on? here is the project link -

thank you so much for your time and help,

Hello!

I have a couple of notes/questions about the setup:

  • I noticed that we have a moving face on the bottom:

If this is a wing (as it looks like), it would be best to set the bottom wall to “Wall” with a “Slip” condition instead.

  • The mesh quality seems to be poor, which is likely causing the simulation to diverge:

Kindly go through the steps on this article, which show you the usual troubleshooting practices when this happens.

Cheers
