Hello,
Please double check your boundary conditions, especially those involving velocities. Currently, the velocity vectors are pointing in the wrong direction, which is causing the issues that you mentioned.
The orientation cube (in the bottom-right corner) should always be used as a reference for the input:
On a side note, if this is a wing simulation, the “Wall 5” boundary condition would normally be a “Slip” wall. It would only be a moving wall if it represents the actual ground.
Cheers,
Ricardo
