is not getting converged. Even the reduction in drag is negligible.

Did you encounter the same problem ?

Thanks

Hi Anant,

The adjoint RANS capability is a priority for SU2 developers team. For the time being we are developing two techniques: frozen eddy viscosity, and a new technique called hybrid adjoint.

Could you please try the new release 2.0.3 using the frozen viscosity adjoint?

Best,
Francisco
