  Hi all, I am following the tutorial for the ANSYS master, optimization module, optimizing turning vanes.
  I follow all the steps of the tutorial, but I can't get the same adjoint residual behavior, they are not converging.
  Is there something missing?
  Best regards, thanks!

  Hi, thanks for your reply, sure, in the attached link you can find it. I am not able to get the residuals to go down although I have followed all the steps. I include the case and data file for you to reproduce the case.

  Copy that. This would be the tutorial, I can't get the last figure right, the residuals don't go down...
  
  This is the problem

  2022R1 and 2023R1, getting same results in both of them.

  What do your results look like? Residuals don't necessarily have to converge for calculations to be correct.

  This is what I obtain, residuals don't converge as the tutorial says.
