Localized model reduction for nonlinear elliptic partial differential equations: localized training, partition of unity, and adaptive enrichment

Kathrin Smetana, Tommaso Taddei

We propose a component-based (CB) parametric model order reduction (pMOR) formulation for parameterized {nonlinear} elliptic partial differential equations (PDEs). CB-pMOR is desig…

Optimal local approximation spaces for parabolic problems

Julia Schleuß, Kathrin Smetana

We propose local space-time approximation spaces for parabolic problems that are optimal in the sense of Kolmogorov and may be employed in multiscale and domain decomposition metho…

Stable and efficient Petrov-Galerkin methods for a kinetic Fokker-Planck equation

Julia Brunken, Kathrin Smetana

We propose a stable Petrov-Galerkin discretization of a kinetic Fokker-Planck equation constructed in such a way that uniform inf-sup stability can be inferred directly from the va…

Randomized residual-based error estimators for the Proper Generalized Decomposition approximation of parametrized problems

Kathrin Smetana, Olivier Zahm

This paper introduces a novel error estimator for the Proper Generalized Decomposition (PGD) approximation of parametrized equations. The estimator is intrinsically random: It buil…

Localized model reduction for parameterized problems

Andreas Buhr, Laura Iapichino, Mario Ohlberger +3

In this contribution we present a survey of concepts in localized model order reduction methods for parameterized partial differential equations. The key concept of localized model…
