A Non intrusive reduced basis method : application to computational fluid dynamics

Abstract : The reduced basis method recent progress have permitted to make the computations reliable thanks to a posteriori estimators . However, it may not always be possible to use the code to perform all the "off-line" computations required for an efficient performance of the reduced basis method. We propose here an alternating approach based on a coarse grid finite element, the convergence of which is accelerated through the reduced basis and an improved post processing.
