Uncertainties quantification (joint work with Dr. Didier Lucor):
- One of my current research activities focuses on the adaptive control of the coupled deterministic-stochastic numerical errors. For CFD problems involving shocks/discontinuities in the deterministic solution, it is well know that the shock propagates in the parametric space as well. If in the deterministic context this problems is quite well adresses, in the stochastic context very few "solid" error estimators adresses the issue and the anisotropy in the parametric space needs to be captured as well. In this context, our aim is to : - firstly, define a solid error estimator for the coupled deterministic-stochastic error capable to control both sources of errors in an adaptive manner and to distinquish which source dominates a calculation; and secondly, the anisotropy in the parametric space needs to be captured.
