An HLL Riemann solver for the hybridised discontinuous Galerkin formulation of compressible flows
Jordi Vila-Pérez, Matteo Giacomini, Ruben Sevilla +1
This work proposes a high-order hybridised discontinuous Galerkin (HDG) formulation of the Harten-Lax-Van Leer (HLL) Riemann solver for compressible flows. A unified framework is i…
Tutorial on Hybridizable Discontinuous Galerkin (HDG) Formulation for Incompressible Flow Problems
Matteo Giacomini, Ruben Sevilla, Antonio Huerta
A hybridizable discontinuous Galerkin (HDG) formulation of the linearized incompressible Navier-Stokes equations, known as Oseen equations, is presented. The Cauchy stress formulat…
A second-order face-centred finite volume method for elliptic problems
Luan M Vieira, Matteo Giacomini, Ruben Sevilla +1
A second-order face-centred finite volume method (FCFV) is proposed. Contrary to the more popular cell-centred and vertex-centred finite volume (FV) techniques, the proposed method…
Hybrid coupling of CG and HDG discretizations based on Nitsche's method
Andrea La Spina, Matteo Giacomini, Antonio Huerta
A strategy to couple continuous Galerkin (CG) and hybridizable discontinuous Galerkin (HDG) discretizations based only on the HDG hybrid variable is presented for linear thermal an…
Nonintrusive proper generalised decomposition for parametrised incompressible flow problems in OpenFOAM
Vasileios Tsiolakis, Matteo Giacomini, Ruben Sevilla +2
The computational cost of parametric studies currently represents the major limitation to the application of simulation-based engineering techniques in a daily industrial environme…
Parametric solutions involving geometry integrated with computer-aided design
Ruben Sevilla, Sergio Zlotnik, Antonio Huerta
The main objective of this work is to describe a general and original approach for computing an off-line solution for a set of parameters describing the geometry of the domain. Tha…
