Weighted Error Estimators for the Incompressible Navier-Stokes Equations
Résumé
We present the application of weighted a posteriori error estimation to the incompressible Navier-Stokes equations. Using information from an appropriate dual problem, we control the discretization error of a functional of the solution as the drag or lift coefficient of an object immerged in a fluid. As test cases we consider a benchmark problem of a chanel flow and the flow around a cylinder in an unbounded domain.
