Abstract: The possibility is explored of creating a postprocessor for a posteriori error estimation of computed target functionals based on the residual generated by a high-accuracy stencil and adjoint parameters as applied to a numerical solution. The applicability of this approach to the supersonic Euler equations is confirmed by computing the density at a control point.

Key words: postprocessor for a posteriori error estimation, error in computed target functionals based on residuals, numerical solution to supersonic Euler equations.
