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.

Stabilized mixed finite element method for the M1 radiation model
(2018-06)
Article
Accés restringit per política de l'editorialIn this work, we present a computational approach for the numerical simulation of thermal radiation. Radiation is modeled by solving a set of two coupled partial differential equations, the so-called M1 model. A Variational ... -

(2018-04)
Article
Accés obertFEMPAR is an open source object oriented Fortran200X scientific software library for the high-performance scalable simulation of complex multiphysics problems governed by partial differential equations at large scales, by ... -
Unified solver for fluid dynamics and aeroacoustics in isentropic gas flows
(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 ... -

Variational Multiscale error estimators for solid mechanics adaptive simulations: an Orthogonal Subgrid Scale approach
(2017-10)
Article
Accés restringit per política de l'editorialIn this work we present a general error estimator for the finite element solution of solid mechanics problems based on the Variational Multiscale method. The main idea is to consider a rich model for the subgrid scales as ... -

Article
Accés obertIn this paper we present the numerical analysis of a three-field stabilized finite element formulation recently proposed to approximate viscoelastic flows. The three-field viscoelastic fluid flow problem may suffer from ... -
Interpolation with restrictions between finite element meshes for flow problems in an ALE setting
(John Wiley & Sons, 2017-06)
Article
Accés restringit per política de l'editorialThe need for remeshing when computing flow problems in domains suffering large deformations has motivated the implementation of a tool that allows the proper transmission of information between finite element meshes. Because ... -
Refficientlib: an efficient load-rebalanced adaptive mesh refinement algorithm for high-performance computational physics meshes

Article
Accés obertIn this paper we present a novel algorithm for adaptive mesh refinement in computational physics meshes in a distributed memory parallel setting. The proposed method is developed for nodally based parallel domain partitions ... -
Space-time balancing domain decomposition
(2017-03)
Article
Accés obertIn this work, we propose two-level space-time domain decomposition preconditioners for parabolic problems discretized using finite elements. They are motivated as an extension to space-time of balancing domain decomposition ... -
Differentiable monotonicity-preserving schemes for discontinuous Galerkin methods on arbitrary meshes
(2017-06)
Article
Accés restringit per política de l'editorialThis work is devoted to the design of interior penalty discontinuous Galerkin (dG) schemes that preserve maximum principles at the discrete level for the steady transport and convection–diffusion problems and the respective ...
