Hi Foamers,
Does anyone know if the implemented BC would work for outlet patches that might present reverse flow?
I am having a lot of trouble trying to reach a solution.
Right know I am sticking with the simpler zeroGradient for U and fixed value for presure and the adjointOutfletVelocity / adjointOutletPressure for the adjoint solver, but as soon as there is reverse flow, the adj continuity errors start to grow.
I can try to modify the adjoint BC, but wanted to see if there is a better solution (and that is already tested, as I am running out of time).

Any help is appreciated.
