A comparison of adjoint and data-centric verification techniques.

By Timothy Michael Wildey, Eric Christopher Cyr, John Nicolas Shadid, Roger Patrick Pawlowski and Thomas Michael Smith

Abstract

This document summarizes the results from a level 3 milestone study within the CASL VUQ effort. We compare the adjoint-based a posteriori error estimation approach with a recent variant of a data-centric verification technique. We provide a brief overview of each technique and then we discuss their relative advantages and disadvantages. We use Drekar::CFD to produce numerical results for steady-state Navier Stokes and SARANS approximations.
