      Hi everybody, 


      I am trying to optimize the geometry of a channel with pillar inside, using the adjoint solver of Fluent.


      I tryed starting with minimizing pressure drop between inlet and outlet. 


      I initialized and when I start the calculation this appear:


      Computing the adjoint for observable pressure-drop


         Iter  Adjoint-continuity  Adjoint-xMom     Adjoint-yMom     Adjoint-zMom      Adjoint-Flowrate


            1     -1.#IND0e+00     -1.#IND0e+00     -1.#IND0e+00    -1.#IND0e+00    -1.#IND0e+00


      ! Adjoint solution is converged


      Anyone had the same problem? could anyone help me?

      That doesn't look like it did anything. That's definitely not convergence. Can you upload a copy of your workbench file?


      Cheers

      Thanks Raef for your reply. I solved it, was a problem with setting my observables. 


      Cheers
