  Hi guys. I have an trouble with my project. I analyze on this domain(pic 1, 2) and i got solution correctly for 19...-14 degree angle of attack, however it starts a residual misbehave(pic 3, 4) at -15 degree. In addition, i use k-w SST model, i am sure with inlet, outlet and wall boundaries, How could i fix it? Thanks...

  Hello:
  This could be representing a transient behavior in your solution. Perhaps, the wake region is not being captured properly.
  One thought I have is that since you are not modeling 0 AoA, you might want to change the orientation of your refined mesh just downstream of the airfoil so it is aligned with the wake region. I would use this refinement (as per the picture) for smaller AoAs.
