A finite element reduced-order model based on adaptive mesh refinement and artificial neural networks
(John Wiley & sons, 2020-02)
Article
Open AccessIn this work, a reduced-order model based on adaptive finite element meshes and a correction term obtained by using an artificial neural network (FAN-ROM) is presented. The idea is to run a high-fidelity simulation by using ... -
An adaptive fixed-mesh ALE method for free surface flows
(2017-01-01)
Article
Open AccessIn this work we present a Fixed-Mesh ALE method for the numerical simulation of free surface flows capable of using an adaptive finite element mesh covering a background domain. This mesh is successively refined and unrefined ... -
An oil sloshing study: adaptive fixed-mesh ALE analysis and comparison with experiments
(Springer, 2019-05)
Article
Open AccessWe report in this work a numerical analysis of the sloshing of a squared tank partially filled with a domestic vegetable oil. The tank is subject to controlled motions with a shake table. The free-surface evolution is ... -
Dynamic term-by-term stabilized finite element formulation using orthogonal subgrid-scales for the incompressible Navier–Stokes problem
(2019-06)
Article
Open AccessIn this paper, we propose and analyze the stability and the dissipative structure of a new dynamic term-by-term stabilized finite element formulation for the Navier–Stokes problem that can be viewed as a variational ... -
Logarithmic conformation reformulation in viscoelastic flow problems approximated by a VMS-type stabilized finite element formulation
(2019-09)
Article
Open AccessThe log-conformation reformulation, originally proposed by Fattal and Kupferman (2004), allows computing incompressible viscoelastic problems with high Weissenberg numbers which are impossible to solve with the typical ... -
Pseudoplastic fluid flows for different Prandtl numbers: steady and time-dependent solutions
(2019-11)
Article
Open AccessIn this work, a variational multiscale (VMS) finite element formulation is used to approximate numerically the natural convection in square cavity with differentially heated from sidewalls problem for Newtonian and power-law ... -
Stabilised variational multi-scale finite element formulations for viscoelastic fluids
(2021-05)
Article
Open AccessThe objective of this article is to summarise the work that we have been doing as a group in the context of stabilised finite element formulations for viscoelastic fluid flows. Viscoelastic fluids are complex non-Newtonian ... -
Stationary and time-dependent numerical approximation of the lid-driven cavity problem for power-law fluid flows at high Reynolds numbers using a stabilized finite element formulation of the VMS type
(2018-07)
Article
Open AccessIn this work, a variational multiscale finite element formulation is used to approximate numerically the lid-driven cavity flow problem for high Reynolds numbers. For Newtonian fluids, this benchmark case has been extensively ...
