A REDUCED BASIS FRAMEWORK: APPLICATION TO LARGE SCALE NON-LINEAR MULTI-PHYSICS PROBLEMS

In this paper we present applications of the reduced basis method (RBM) to large-scale non-linear multi-physics problems. We rst describe the mathematical framework in place and in particular the Empirical Interpolation Method (EIM) to recover an ane decomposition and then we propose an implementation using the open-source library Feel++ which provides both the reduced basis and nite element layers. Large scale numerical examples are shown and are connected to real industrial applications arising from the High Field Resistive Magnets development at the Laboratoire National des Champs Magn etiques Intenses.
