Class
    Foam::adjointOutletVelocityFvPatchVectorField
 
Description
    Provides the adjoint outlet velocity values (i.e. adjoint velocity in
    case of a zeroGradient U boundary condition). Can have stability issues
    in cases of backflow of the primal velocity.
    The adjointOutletVelocityFlux should preferably be used.
