Online adaptive non-intrusive model reduction via manifold interpolation and subspace updates: application to FSI convergence acceleration
Azzeddine Tiba, Florian de Vuyst, Iraj Mortazavi
We introduce a novel online adaptive non-intrusive reduced-order modeling strategy for parameterized dynamical systems involving parameter and time-dependent reduced bases. The pro…
Learning features from Newton's algorithm: a way to accelerate nonlinear parametrized PDE solvers
Rémy Vallot, Florian de Vuyst, Thibault Dairay +1
It is well known that Newton's method converges faster when the initial guess is closer to a root of a system of nonlinear equations. In this paper, a two-stage Newton initial gues…
Machine-Learning Enhanced Predictors for Accelerated Convergence of Partitioned Fluid-Structure Interaction Simulations
Azzeddine Tiba, Thibault Dairay, Florian de Vuyst +2
Stable partitioned techniques for simulating unsteady fluid-structure interaction (FSI) are known to be computationally expensive when high added-mass is involved. Multiple couplin…
Non-intrusive reduced order models for partitioned fluid-structure interactions
Azzeddine Tiba, Thibault Dairay, Florian de Vuyst +2
The main goal of this work is to develop a data-driven Reduced Order Model (ROM) strategy from high-fidelity simulation result data of a Full Order Model (FOM). The goal is to pred…
Data-driven kinematics-consistent model order reduction of fluid-structure interaction problems: application to deformable microcapsules in a Stokes flow
Claire Dupont, Florian De Vuyst, Anne-Virginie Salsac
In this paper, we present a generic approach of a dynamical data-driven model order reduction technique for three-dimensional fluid-structure interaction problems. A low-order cont…
A mixed EIM-SVD tensor decomposition for bivariate functions
Florian De Vuyst, Asma Toumi
In this paper we present a mixed EIM-SVD tensor decomposition for bivariate functions. This method is composed, as its name suggests, of two main steps. The first one, provides an…
Control Synthesis of Nonlinear Sampled Switched Systems using Euler's Method
Adrien Le Coënt, Florian De Vuyst, Ludovic Chamoin +1
In this paper, we propose a symbolic control synthesis method for nonlinear sampled switched systems whose vector fields are one-sided Lipschitz. The main idea is to use an approxi…
Lagrange-Flux schemes and the entropy property
Florian De Vuyst
The Lagrange-Flux schemes are Eulerian finite volume schemes that make use of an approximate Riemann solver in Lagrangian description with particular upwind convective fluxes. They…
Lagrange-flux schemes: reformulating second-order accurate Lagrange-remap schemes for better node-based HPC performance
Florian De Vuyst, Thibault Gasc, Renaud Motte +2
In a previous paper, we have achieved the performance analysis of staggered Lagrange-remap schemes, a class of solvers widely used for Hydrodynamics applications. This paper is dev…
Stable and accurate interface capturing advection schemes
Florian De Vuyst, Marie Béchereau, Thibault Gasc +3
In this paper, stable and "low-diffusive" multidimensional interface capturing (IC) schemes using slope limiters are discussed. It is known that direction-by-direction slope-limite…
Distributed Synthesis of State-Dependent Switching Control
Adrien Le Coënt, Laurent Fribourg, Nicolas Markey +2
We present a correct-by-design method of state-dependent control synthesis for linear discrete-time switching systems. Given an objective region R of the state space, the method bu…
