Neural-Manifold Primal-Dual Model Order Reduction and Hyper-Reduction for Nonlinear Parametric Variational Inequalities
Sofiane Ezzehi, Virginie Ehrlacher, Guillaume Enchéry +1
We propose a model order reduction framework for nonlinear parametrized variational inequalities arising in computational mechanics. The high-dimensional model is written in mixed…
Model order reduction for parametrized variational inequalities: application to crowd motion
Giulia Sambataro, Virginie Ehrlacher
This work investigates model order reduction for time-dependent parametrized variational inequalities, with a focus on discrete contact problems. As a prototypical example, we cons…
Optimal morphings for model-order reduction for poorly reducible problems with geometric variability
Abbas Kabalan, Fabien Casenave, Felipe Bordeu +2
We propose a new model-order reduction framework to poorly reducible problems arising from parametric partial differential equations with geometric variability. In such problems, t…
Elasticity-based morphing technique and application to reduced-order modeling
Abbas Kabalan, Fabien Casenave, Felipe Bordeu +2
The aim of this article is to introduce a new methodology for constructing morphings between shapes that have identical topology. The morphings are obtained by deforming a referenc…
A reduced basis method for frictional contact problems formulated with Nitsche's method
Idrissa Niakh, Guillaume Drouet, Virginie Ehrlacher +1
We develop an efficient reduced basis method for the frictional contact problem formulated using Nitsche's method. We focus on the regime of small deformations and on Tresca fricti…
Low-rank approximation of linear parabolic equations by space-time tensor Galerkin methods
Thomas Boiveau, Virginie Ehrlacher, Alexandre Ern +1
We devise a space-time tensor method for the low-rank approximation of linear parabolic evolution equations. The proposed method is a stable Galerkin method, uniformly in the discr…
A progressive reduced basis/empirical interpolation method for nonlinear parabolic problems
Amina Benaceur, Alexandre Ern, Virginie Ehrlacher +1
We investigate new developments of the combined Reduced-Basis and Empirical Interpolation Methods (RB-EIM) for parametrized nonlinear parabolic problems. In many situations, the co…
