ANiComp - Anàlisi numèrica i computació científica
El grup ha treballat en diversos temes relacionats amb la simulació de problemes complexos en ciència i enginyeria computacional governats per equacions en derivades parcials. Per una banda, s'ha treballat en el desenvolupament d'algorismes de descomposició de dominis multinivell altament escalables que puguin explotar de forma eficient els supercomputadors més grans del món, posicionant el codi científic del grup en el HIGH-Q club dels codis més escalables del món. Per una altra banda, s'ha treballat en la simulació de manufactura additiva.

Variational multiscale error estimators for the adaptive mesh refinement of compressible flow simulations
(2018-08)
Article
Accés restringit per política de l'editorialThis article investigates an explicit a-posteriori error estimator for the finite element approximation of the compressible Navier–Stokes equations. The proposed methodology employs the Variational Multi-Scale framework, ... -
Approximation of the shallow water equations with higher order finite elements and variational multiscale methods
(2018-01)
Article
Accés obertIn this article, we present approximations with finite elements of high order using stabilized variational multiscale methods to approximate the equations of motion of a fluid in shallow waters. We write these equations ... -

(2012)
Text en actes de congrés
Accés restringit per política de l'editorialThe paper investigates the multi-objective design optimisation of stamping process to control both the shape and quality of final Advanced High Strength Steels (AHSSs) in terms of springback and safety using Distributed ... -
Driving mechanisms and streamwise homogeneity in molecular dynamics simulations of nanochannel flows
(2018-01-12)
Article
Accés obertIn molecular dynamics simulations, nanochannel flows are usually driven by a constant force, that aims to represent a pressure difference between inlet and outlet, and periodic boundary conditions are applied in the ... -
The aggregated unfitted finite element method for elliptic problems
(2018-07)
Article
Accés restringit per política de l'editorialUnfitted finite element techniques are valuable tools in different applications where the generation of body-fitted meshes is difficult. However, these techniques are prone to severe ill conditioning problems that obstruct ... -

Article
Accés restringit per política de l'editorialIn this work we solve the compressible Navier–Stokes equations written in primitive variables in order to simulate low Mach number aeroacoustic flows. We develop a Variational Multi-Scale formulation to stabilize the finite ... -
Robust and scalable domain decomposition solvers for unfitted finite element methods
(2017-10)
Article
Accés restringit per política de l'editorialUnfitted finite element methods, e.g., extended finite element techniques or the so-called finite cell method, have a great potential for large scale simulations, since they avoid the generation of body-fitted meshes and ... -

(2018-06)
Article
Accés restringit per política de l'editorialThe high computational cost of solving numerically the fully compressible Navier–Stokes equations, together with the poor performance of most numerical formulations for compressible flow in the low Mach number regime, has ... -
Variational multiscale approximation of the one-dimensional forced Burgers equation: the role of orthogonal subgrid scales in turbulence modeling
(2018-02)
Article
Accés restringit per política de l'editorialA numerical approximation for the one-dimensional Burgers equation is proposed by means of the orthogonal subgrid scales–variational multiscale (OSGS-VMS) method. We evaluate the role of the variational subscales in ...
