inviscid Adjoint variables on airfoil profile

Hi everyone,
I wonder if anyone has had experience comparing SU2 adjoint solutions at airfoils profile for different mesh refinement. In the attached figure I plot the surface value of the density discrete adjoint variable for drag on 5 different triangular meshes (each one obtained from the previous one by uniform refinement) for inviscid NACA0012 flow with M = 0.8 and aoa = 1.25. (the solution has not been obtained with SU2 but with DLR's Tau code; I'm trying to see if anyone has had this kind of experience with SU2). Continuous adjoint shows similar trends, and the sensitivities are OK (they do not show the same lack of mesh convergence as the surface adjoint values). Any comments would be appreciated. Regards, |
