Hi,

I am trying to optimise a reducing elbow in fluent adjoint solver for pressure drop. It found the critical section, but makes it narrower and increases the pressure drop. What am I doing wrong, maybe its the shape?
Am using air, non compressible, should be fairly easy to solve.

Cheers,

Steffen
