“Adjoint-Based Control of Model and Discretization Errors for Gas and Water Supply Networks” is a paper by Pia Domschke Oliver Kolb Jens Lang published in 2011.

Recently, we have published an algorithm to adaptively control model and discretization errors in simulations for gas supply networks [6, 7] . This is ...

We investigate the concept of dual-weighted residuals for measuring model errors in the numerical solution of nonlinear partial differential equations.

With these error estimators we present an algorithm that automatically steers the discretization and the models used to maintain a given accuracy. We show ...
