N2 - This paper presents a framework for the reduction of the spatial, temporal and algebraic error by use of the discrete adjoint solution in a time integrated functional (i.e. Lift, Drag, etc.) for problems of aerodynamic interest. The three types of error, along with cost estimates to refine each, are used to selectively adapt the discretization to reduce the error in the functional in the most eficient manner. Three test problems are used to demonstrate the algorithm and the resulting convergence tolerances, temporal and spatial discretization are displayed.
