On Adjoint Equations for Error Analysis and Optimal Grid Adaptation in CFD
Frontiers of Computational Fluid Dynamics 1998
This paper explains how the solutions of appropriate adjoint equations can be used to estimate the errors in important integral quantities, such as lift and drag, obtained from CFD computations. These error estimates can be used to obtain improved estimates of the integral quantities, or as the basis for optimal grid adaptation. The theory is presented for both nite volume and nite element approximations. For a node-based nite volume discretisation of the Euler equations on unstructured grids,doi:10.1142/9789812815774_0009 fatcat:xaho35njljgk5pfsbymurshitm
