Model order reduction of an ultraweak and optimally stable variational formulation for parametrized reactive transport problems
Christian Engwer, Mario Ohlberger, Lukas Renelt
This contribution introduces a model order reduction approach for an advection-reaction problem with a parametrized reaction function. The underlying discretization uses an ultrawe…
An optimally stable approximation of reactive transport using discrete test and infinite trial spaces
Lukas Renelt, Christian Engwer, Mario Ohlberger
In this contribution we propose an optimally stable ultraweak Petrov-Galerkin variational formulation and subsequent discretization for stationary reactive transport problems. The…
Adaptive Localized Reduced Basis Methods for Large Scale Parameterized Systems
Tim Keil, Mario Ohlberger, Felix Schindler
In this contribution, we introduce and numerically evaluate a certified and adaptive localized reduced basis method as a local model in a trust-region optimization method for param…
Application of Deep Kernel Models for Certified and Adaptive RB-ML-ROM Surrogate Modeling
Tizian Wenzel, Bernard Haasdonk, Hendrik Kleikamp +2
In the framework of reduced basis methods, we recently introduced a new certified hierarchical and adaptive surrogate model, which can be used for efficient approximation of input-…
