Hi

I was running adjoint simulation for RANS case for Onera M6 wing on hybrid coarse mesh.

The adjoint simulation is converging with "Frozen viscosity" option as "Yes"
but it is diverging when the option is kept as "No".

Can anyone say why is this happening ?

I am attaching the convergence plot and the .cfg file

Thanks
Anant
