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.

Global, regional, and national burden of diabetes from 1990 to 2021, with projections of prevalence to 2050: a systematic analysis for the Global Burden of Disease Study 2021
(2023-06)
Article
Open AccessBackground Diabetes is one of the leading causes of death and disability worldwide, and affects people regardless of country, age group, or sex. Using the most recent evidentiary and analytical framework from the Global ... -
An accurate approach to simulate friction stir welding processes using adaptive formulation refinement
(Elsevier, 2023-07-07)
Article
Restricted access - publisher's policyA novel Adaptive Formulation Refinement (AFR) strategy for Friction Stir Welding (FSW) problems is presented. In FSW, the accurate computation of strains is crucial to correctly predict the highly non-linear material ... -
A variational multiscale stabilized finite element formulation for Reissner–Mindlin plates and Timoshenko beams
(Elsevier, 2023-05)
Article
Open AccessThe theories for thick plates and beams, namely Reissner–Mindlin’s and Timoshenko’s theories, are well known to suffer numerical locking when approximated using the standard Galerkin finite element method for small ... -
Numerical simulation of Fluid–Structure Interaction problems with viscoelastic fluids using a log-conformation reformulation
(2023-05)
Article
Open AccessIn this paper the numerical simulation of the interaction between Oldroyd-B viscoelastic fluid flows and hyperelastic solids is approached. The algorithm employed is a classical block-iterative scheme, in which the solid ... -
A stabilized mixed three-field formulation for stress accurate analysis including the incompressible limit in finite strain solid dynamics
(2023)
Article
Restricted access - publisher's policyIn this work a new methodology for finite strain solid dynamics problems for stress accurate analysis including the incompressible limit is presented. In previous works, the authors have presented the stabilized mixed ... -
Mixed stabilized finite element methods in linear elasticity for the velocity–stress equations in the time and the frequency domains
(2023-02)
Article
Restricted access - publisher's policyIn this work we present stabilized finite element methods for the mixed velocity–stress elasticity equations and for its irreducible velocity form. This is done both for the time and frequency domains, the latter being ... -
A multi-criteria h-adaptive finite-element framework for industrial part-scale thermal analysis in additive manufacturing processes
(2022-12)
Article
Open AccessThis work presents an h-adaptive finite-element (FE) strategy to address the numerical simulation of additive manufacturing (AM) of large-scale parts. The wire-arc additive manufacturing is chosen as the demonstrative ... -
Finite element approximation of wave problems with correcting terms based on training artificial neural networks with fine solutions
(2022-09)
Article
Restricted access - publisher's policyIn this paper we present a general idea to correct coarse models by introducing a correcting term designed from fine solutions that can be then applied to situations in which a fine solution is not available. We apply this ... -
On the use of ensemble averaging techniques to accelerate the Uncertainty Quantification of CFD predictions in wind engineering
(2022-09)
Article
Open AccessIn this work we focus on reducing the wall clock time required to compute statistical estimators of highly chaotic incompressible flows on high performance computing systems. Our approach consists of replacing a single ... -
A VMS–based fractional step technique for the compressible Navier–Stokes equations using conservative variables
(2022-06)
Article
Restricted access - publisher's policyIn this paper we address the compressible Navier–Stokes equations written in the so-called conservative formulation. In particular, we focus on the possibility of uncoupling the computation of the problem unknowns, namely, ... -
Modal analysis of elastic vibrations of incompressible materials using a pressure-stabilized finite element method
(2022-09)
Article
Restricted access - publisher's policyThis paper describes a modal analysis technique to approximate the vibrations of incompressible elastic solids using a stabilized finite element method to approximate the associated eigenvalue problem. It is explained why ... -
Geometrical discretisations for unfitted finite elements on explicit boundary representations
(2022-07-01)
Article
Restricted access - publisher's policyUnfitted (also known as embedded or immersed) finite element approximations of partial differential equations are very attractive because they have much lower geometrical requirements than standard body-fitted formulations. ...
