Currently, I'm trying to use the Nektar++ to conduct global sensitivity analysis on the cylinder flow at Re=100. The SFD base flow file is generated through the examples given in *solvers/IncNavierStokesSolver/Tests/**Cyl_AdaptiveSFD.xml*. After that, I change the session file according to the tutorials to get the direct and adjoint modes. But I can only get the direct modes correctly. I don't know whether there are some problems with my settings in the adjoint session file (in the attachment). Can anyone help me? Looking forward to your reply! Sincerely, Sekar Verma
