A domain decomposition framework for fluid-structure interaction problems

Alfio Quarteroni, Simone Deparis, Marco Discacciati

In this note we review some classical algorithms for fluid-structure interaction problems and we propose an alternative viewpoint mutuated from the domain decomposition theory. This approach yields preconditioned Richardson iterations on the Steklov-Poinca ...

Fluid-structure algorithms based on Steklov-Poincaré operators

Alfio Quarteroni, Simone Deparis, Marco Discacciati, Gilles Fourestey

In this paper we review some classical algorithms for fluid-structure interaction problems and we propose an alternative viewpoint mutuated from the domain decomposition theory. This approach yields preconditioned Richardson iterations on the Steklov-Poinc ...

The non-circular shape of FloWatch®-PAB prevents the need for pulmonary artery reconstruction after banding

Alfio Quarteroni, Paolo Zunino, Ludwig Von Segesser

To evaluate the differences between non-circular shape of FloWatch®-PAB and conventional pulmonary artery (PA) banding. Methods: Geometrical analysis. Conventional banding and FloWatch®-PAB perimeters were plotted against cross-sections. Computational flui ...

Shape design in aorto-coronaric bypass anastomoses using perturbation theory

Alfio Quarteroni, Gianluigi Rozza

We present a new approach in the study of aorto-coronaric bypass anastomoses configurations based on small perturbation theory. The theory of optimal control based on adjoint formulation is applied in order to optimize the shape of the zone of the incoming ...

Mathematical models and numerical simulations for the America's Cup

Alfio Quarteroni, Nicola Parolini

This paper presents a review of the mathematical models which can be adopted to describe the different physical phenomena characterizing the flow around a sailing yacht. The complete model accounting for laminar-turbulent transition regime, free-surface dy ...

Mathematical and numerical models for transfer of low-density lipoproteins through the arterial walls: A new methodology for the model set up with applications to the study of disturbed lumenal flow

Alfio Quarteroni, Paolo Zunino

In this work we introduce and discuss several mathematical models, based on partial differential equations, devised to study the coupled transport of macromolecules as low-density lipoproteins in the blood stream and in the arterial walls. These models are ...

Optimal control in heterogeneous domain decomposition methods

Alfio Quarteroni

Some new domain decomposition methods (DDM) based on optimal control approach are introduced for the coupling of first- and second-order equations on overlapping subdomains. Several cost functionals and control functions are proposed. Uniqueness and existe ...

Analysis of a geometrical multiscale blood flow model based on the coupling of ODEs and hyperbolic PDEs

Alfio Quarteroni

For the numerical simulation of the circulatory system, geometrical multiscale models based on the coupling of systems of differential equations with different spatial dimensions are becoming common practice. In this paper we address the mathematical analy ...
