Nonintrusive reduced order model for parametric solutions of inertia relief problems
F. Cavaliere, S. Zlotnik, R. Sevilla +2
The Inertia Relief (IR) technique is widely used by industry and produces equilibrated loads allowing to analyze unconstrained systems without resorting to the more expensive full…
A non-oscillatory face-centred finite volume method for compressible flows
Jordi Vila-Pérez, Matteo Giacomini, Ruben Sevilla +1
This work presents the face-centred finite volume (FCFV) paradigm for the simulation of compressible flows. The FCFV method defines the unknowns at the face barycentre and uses a h…
HDGlab: An open-source implementation of the hybridisable discontinuous Galerkin method in MATLAB
Matteo Giacomini, Ruben Sevilla, Antonio Huerta
This paper presents HDGlab, an open source MATLAB implementation of the hybridisable discontinuous Galerkin (HDG) method. The main goal is to provide a detailed description of both…
Hybridisable discontinuous Galerkin formulation of compressible flows
Jordi Vila-Pérez, Matteo Giacomini, Ruben Sevilla +1
This work presents a review of high-order hybridisable discontinuous Galerkin (HDG) methods in the context of compressible flows. Moreover, an original unified framework for the de…
Separated response surfaces for flows in parametrised domains: comparison of a priori and a posteriori PGD algorithms
Matteo Giacomini, Luca Borchini, Ruben Sevilla +1
Reduced order models (ROM) are commonly employed to solve parametric problems and to devise inexpensive response surfaces to evaluate quantities of interest in real-time. There are…
Hybridisable discontinuous Galerkin solution of geometrically parametrised Stokes flows
Ruben Sevilla, Luca Borchini, Matteo Giacomini +1
This paper proposes a novel computational framework for the solution of geometrically parametrised flow problems governed by the Stokes equation. The proposed method uses a high-or…
Parametric solutions of turbulent incompressible flows in OpenFOAM via the proper generalised decomposition
Vasileios Tsiolakis, Matteo Giacomini, Ruben Sevilla +2
An a priori reduced order method based on the proper generalised decomposition (PGD) is proposed to compute parametric solutions involving turbulent incompressible flows of interes…
A second-order face-centred finite volume method on general meshes with automatic mesh adaptation
Matteo Giacomini, Ruben Sevilla
A second-order face-centred finite volume strategy on general meshes is proposed. The method uses a mixed formulation in which a constant approximation of the unknown is computed o…
