A Note on the Reliability of Goal-Oriented Error Estimates for Galerkin Finite Element Methods with Nonlinear Functionals

Brian N. Granzow, Stephen D. Bond, D. Thomas Seidl +1

We consider estimating the discretization error in a nonlinear functional $J(u)$ in the setting of an abstract variational problem: find $u\in \mathcal{V}$ such that $B(u,φ) = L(…
