A Review of Element-Based Galerkin Methods for Numerical Weather Prediction: Finite Elements, Spectral Elements, and Discontinuous Galerkin
Marras, Simone; Kelly, James F.; Moragues, Margarida; Müller, Andreas; Kopera, Michal A.; Vázquez, Mariano; Giraldo, Francis X.; Houzeaux, Guillaume; Jorba, Oriol (Springer, 2015-05-19)
Article
Accés obertNumerical weather prediction (NWP) is in a period of transition. As resolutions increase, global models are moving towards fully nonhydrostatic dynamical cores, with the local and global models using the same governing ... -
A variational multiscale stabilized finite element method for the solution of the Euler equations of nonhydrostatic stratified flows
Marras, Simone; Moragues, Margarida; Vázquez, Mariano; Jorba Casellas, Oriol; Houzeaux, Guillaume (2013-03-01)
Article
Accés restringit per política de l'editorialWe present a compressible version of the variational multiscale stabilization (VMS) method applied to the finite element (FE) solution of the Euler equations for nonhydrostatic stratified flows. This paper is meant to ... -
An unstructured CFD approach for numerical weather prediction
Aubry, Romain; Vázquez, Mariano; Houzeaux, Guillaume; Cela Espín, José M.; Marras, Simone (2010)
Text en actes de congrés
Accés restringit per política de l'editorialThe aim of this paper is twofold. First, it is difficult for a newcomer in the Numerical Weather Prediction (NWP) community to find similarities with Computational Fluid Dynamics (CFD) techniques as far as the numerical ... -
Application of a Galerkin finite element scheme to atmospheric buoyant and gravity driven flows
Marras, Simone; Vázquez, Mariano; Jorba Casellas, Oriol; Aubry, Romain; Houzeaux, Guillaume; Baldasano Recio, José María (2010)
Text en actes de congrés
Accés restringit per política de l'editorialThe application of a new finite element (FE) technique for the solution of stratified, non-hydrostatic, low-Mach number flows is introduced in the context of mesoscale atmospheric modeling. In this framework, a Compressible ... -
Desarrollo de la competencia transversal “Tercera Lengua” – aplicación a proyectos de ingeniería aeronáutica
García-Almiñana, Daniel; Gassó Domingo, Santiago; Casulleras, Ferran; Fernandez, Joan Carles; Isern, Salvador; Marras, Simone; Pérez Llera, Luis Manuel (2010)
Comunicació de congrés
Accés obertLa docencia que suele impartirse en las asignaturas de Proyectos admite la aplicación de un gran número de metodologías docentes entre las que destacan el ABP – Aprendizaje Basado en Proyectos (PBL – Project Based Learning) ... -
Simulations of moist convection by a variational multiscale stabilized finite element method
Marras, Simone; Moragues, Margarida; Vázquez, Mariano; Jorba Casellas, Oriol; Houzeaux, Guillaume (2013-11-01)
Article
Accés restringit per política de l'editorialA variational multiscale stabilized finite element scheme is presented for the solution of moist atmospheric flows. The fully compressible Euler equations are coupled to a system of three advection equations that model the ... -
Variational multiscale stabilization of finite and spectral elements for dry and moist atmospheric problems
Marras, Simone (Universitat Politècnica de Catalunya, 2012-12-10)
Tesi
Accés obertIn this thesis the finite and spectral element methods (FEM and SEM, respectively) applied to problems in atmospheric simulations are explored through the common thread of Variational Multiscale Stabilization (VMS). This ... -
Variational multiscale stabilization of high-order spectral elements for the advection-diffusion equation
Marras, Simone; Kelly, James F.; Giraldo, Frank X.; Vázquez, Mariano (2012)
Article
Accés restringit per política de l'editorialOne major issue in the accurate solution of advection-dominated problems by means of high-order methods is the ability of the solver to maintain monotonicity. This problem is critical for spectral elements, where Gibbs ...
