POD-Based Model-Order Reduction for Discontinuous Parameters

open access: yesFluids, 2022
Reduced-order models (ROMs) based on proper orthogonal decomposition (POD) are widely used in industry. Due to the rigid requirements on the input data, these methods struggle with discontinuous parameters, e.g., optional rear spoiler on a car.

Model Order Reduction by Using Improved Approximation Techniques

open access: yesScientific Journal of King Faisal University: Basic and Applied Sciences, 2020
A simplified approach for model order reduction (MOR) is presented in this article using the balanced singular perturbation approximation (BSPA) approach applicable to large-scale linear dynamical (LSLD) systems.

REDUCED-ORDER MODELLING OF PARAMETERIZED TRANSIENT FLOWS IN CLOSED-LOOP SYSTEMS [PDF]

open access: yesEPJ Web of Conferences, 2021
In this paper, two Galerkin projection based reduced basis approaches are investigated for the reduced-order modeling of parameterized incompressible Navier-Stokes equations for laminar transient flows. The first approach solves only the reduced momentum

On the model order reduction of confined plasticity [PDF]

open access: yesAIP Conference Proceedings, 2016
Forming processes usually involve irreversible plastic transformations. The calculation in that case becomes cumbersome when large parts and processes are considered. Recently Model Order Reduction techniques opened new perspectives for an accurate and fast simulation of mechanical systems. In some processes, plastic deformations remain very localized,

Efficient Wildland Fire Simulation via Nonlinear Model Order Reduction

open access: yesFluids, 2021
We propose a new hyper-reduction method for a recently introduced nonlinear model reduction framework based on dynamically transformed basis functions and especially well-suited for transport-dominated systems.

Model-order reduction for hyperbolic relaxation systems

open access: yesInternational Journal of Nonlinear Sciences and Numerical Simulation, 2022
Abstract We propose a novel framework for model-order reduction of hyperbolic differential equations. The approach combines a relaxation formulation of the hyperbolic equations with a discretization using shifted base functions. Model-order reduction techniques are then applied to the resulting system of coupled ordinary differential ...

Error estimation of a proper orthogonal decomposition reduced model of a permanent magnet synchronous machine [PDF]

open access: yes, 2014
Model order reduction methods, like the proper orthogonal decomposition (POD), enable to reduce dramatically the size of a finite element (FE) model.

Symplectic Model Order Reduction with Non-Orthonormal Bases

open access: yesMathematical and Computational Applications, 2019
Parametric high-fidelity simulations are of interest for a wide range of applications. However, the restriction of computational resources renders such models to be inapplicable in a real-time context or in multi-query scenarios.
