Finite element based model order reduction for parametrized one-way coupled steady state linear thermomechanical problems
Nirav Vasant Shah, Michele Girfoglio, Peregrina Quintela +4
This contribution focuses on the development of Model Order Reduction (MOR) for one-way coupled steady state linear thermomechanical problems in a finite element setting. We apply…
An efficient FV-based Virtual Boundary Method for the simulation of fluid-solid interaction
Michele Girfoglio, Giovanni Stabile, Andrea Mola +1
In this work, the Immersed Boundary Method (IBM) with feedback forcing introduced by Goldstein et al. (1993) and often referred in the literature as the Virtual Boundary Method (VB…
Consistency of the Full and Reduced Order Models for Evolve-Filter-Relax Regularization of Convection-Dominated, Marginally-Resolved Flows
Maria Strazzullo, Michele Girfoglio, Francesco Ballarin +2
Numerical stabilization is often used to eliminate (alleviate) the spurious oscillations generally produced by full order models (FOMs) in under-resolved or marginally-resolved sim…
The Neural Network shifted-Proper Orthogonal Decomposition: a Machine Learning Approach for Non-linear Reduction of Hyperbolic Equations
Davide Papapicco, Nicola Demo, Michele Girfoglio +2
Models with dominant advection always posed a difficult challenge for projection-based reduced order modelling. Many methodologies that have recently been proposed are based on the…
Thermomechanical modelling for industrial applications
Nirav Vasant Shah, Michele Girfoglio, Gianluigi Rozza
In this work we briefly present a thermomechanical model that could serve as starting point for industrial applications. We address the non-linearity due to temperature dependence…
A Hybrid Reduced Order Model for nonlinear LES filtering
Michele Girfoglio, Annalisa Quaini, Gianluigi Rozza
We develop a Reduced Order Model (ROM) for a Large Eddy Simulation (LES) approach that combines a three-step algorithm called Evolve-Filter-Relax (EFR) with a computationally effic…
Pressure stabilization strategies for a LES filtering Reduced Order Model
Michele Girfoglio, Annalisa Quaini, Gianluigi Rozza
We present a stabilized POD-Galerkin reduced order method (ROM) for a Leray model. For the implementation of the model, we combine a two-step algorithm called Evolve-Filter (EF) wi…
Fluid-structure interaction simulations with a LES filtering approach in solids4Foam
Michele Girfoglio, Annalisa Quaini, Gianluigi Rozza
The goal of this paper is to test solids4Foam, the fluid-structure interaction (FSI) toolbox developed for foam-extend (a branch of OpenFOAM), and assess its flexibility in handlin…
