Error Estimation of goal oriented functional arising from iterative solution of Euler Equation

A.K. Alekseev, I. M. Navon

Error estimation of goal oriented functional arising from an iteration stopping criterion is considered for solution of the steady Euler problem. The functional error is calculated using an iteration residual and adjoint parameters. Numerical tests demonstrate the applicability of this approach for the steady 2-D Euler equations. Keywords: steady Euler equations, iteration error, adjoint equations.
