incompressible 3D wing

[benoitpaillard]

Hi all,

I'm trying to make a 3D lifting surface work in incompressible condition. I've adapted onera wing with DASimpleFoam, but I cannot find a way to make the adjoint converge : KSP residual just remain at an almost constant value. The case is attached.

My understanding is the following

• I don't think it makes sense to use pcFillLevel or jacMatReOrdering because the case is basic and should converge easily
• normalizeStates has a big impact on KSP residuals, so maybe there something I didn't understand here in term of convergence control.

Thanks for your help

Please use bounded Gauss upwind for div(pc) in fvScheme. Also, check this: https://dafoam.github.io/mydoc_get_started_faq.html#why-the-adjoint-equation-is-not-converging

thanks a lots, it is now functional.
