Schur complement domain decomposition for 3D fluid - 2D plate interaction system: analysis and preconditioning
Lander Besabe, Hyesuk Lee
Fluid-structure interaction problems involving three-dimensional fluids coupled with thin elastic plates arise in many engineering applications and present significant computationa…
An isotropic recovery-based error estimator algorithm for mesh adaptation in a finite volume environment with application to atmospheric flows
Lander Besabe, Michele Girfoglio, Simona Perotto +2
We develop an Isotropic Recovery-based Error Estimator (IREE) to drive mesh adaptation within a finite volume framework. Recovery-based error estimators are widely used in practice…
Finite element approximation for a reformulation of a 3D fluid-2D plate interaction system
Lander Besabe, Hyesuk Lee
We study a finite element approximation of a coupled fluid-structure interaction consisting of a three-dimensional incompressible viscous fluid governed by the unsteady Stokes equa…
Randomized Proper Orthogonal Decomposition for data-driven reduced order modeling of a two-layer quasi-geostrophic ocean model
Lander Besabe, Michele Girfoglio, Annalisa Quaini +1
The two-layer quasi-geostrophic equations (2QGE) serve as a simplified model for simulating wind-driven, stratified ocean flows. However, their numerical simulation remains computa…
Data-driven reduced order modeling of a two-layer quasi-geostrophic ocean model
Lander Besabe, Michele Girfoglio, Annalisa Quaini +1
The two-layer quasi-geostrophic equations (2QGE) is a simplified model that describes the dynamics of a stratified, wind-driven ocean in terms of potential vorticity and stream fun…
Linear and nonlinear filtering for a two-layer quasi-geostrophic ocean model
Lander Besabe, Michele Girfoglio, Annalisa Quaini +1
Although the two-layer quasi-geostrophic equations (2QGE) are a simplified model for the dynamics of a stratified, wind-driven ocean, their numerical simulation is still plagued by…
