..., is obtained by combining proper orthogonal decomposition with empirical interpolation method. Originality/value – The authors report a speed up factor between 10 and 15. k=exchange current density and reaction rate κ_l(c_{l)=ionic conductivity}...

... and look angles. Design/methodology/approach – The suggested approach combines finite-element analysis, projection-based model-order reduction, and empirical interpolation. Findings – The reduced-order models are highly accurate but significantly smaller than the underlying finite-element...

...Raffaele Martone; Alessandro Formisano; D. Lahaye; A. Canova; G. Gruosso; M. Repetto Purpose This work aims to present a multilevel optimization strategy based on manifold‐mapping combined with multiquadric interpolation for the coarse model construction. Design/methodology/approach...
