What is Goal-Oriented Error Control in FEM about?

This document summarizes a paper that develops a combined a posteriori analysis to estimate discretization and iteration errors in computing finite element approximations to elliptic boundary value problems using iterative solvers like multigrid. It derives error estimators for a goal-oriented error estimate between the true solution and the computed finite element solution that accounts for errors due to both discretization and the inexact solution of the discrete equations during iteration. The analysis i
