An adjoint-based a posteriori estimation of iterative convergence error
The iterative convergence error of goal functional is considered for solving the steady problem by time iterations. The functional error is calculated using adjoint parameter and time derivative. The numerical tests demonstrate the applicability of this approach for linear and nonlinear heat conduction equations. (c) 2006 Elsevier Ltd. All rights reserved.
