Numerical simulation of Rhonegletscher from 1874 to 2100

Marco Picasso, Jacques Rappaz, Heinz Blatter, Guillaume Jouvet

Due to climatic change, many Alpine glaciers have significantly retreated during the last century. In this study we perform the numerical simulation of the temporal and spatial change of Rhonegletscher, Swiss Alps, from 1874 to 2007, and from 2007 to 2100. ...

On the use of anisotropic a posteriori error estimators for the adaptative solution of 3D inviscid compressible flows

Marco Picasso

This paper describes the use of an a posteriori error estimator to control anisotropic mesh adaptation for computing inviscid compressible flows. The a posteriori error estimator and the coupling strategy with an anisotropic remesher are first introduced. ...

A new algorithm to simulate the dynamics of a glacier: theory and applications

Marco Picasso, Jacques Rappaz, Heinz Blatter, Guillaume Jouvet

We propose a novel Eulerian algorithm to compute the changes of a glacier geometry for given mass balances. The surface of a glacier is obtained by solving a transport equation for the volume of fluid (VOF). The surface mass balance is taken into account b ...

Multiscale algorithm with patches of finite elements

Marco Picasso, Jacques Rappaz, Vittoria Augusta Rezzonico Janka

We develop a discretization and solution technique for elliptic problems whose solutions may present strong variations, singularities, boundary layers and oscillations in localized regions. We start with a coarse finite element discretization with a mesh s ...

An adaptive algorithm for the Stokes problem using continuous, piecewise linear stabilized finite elements and meshes with high aspect ratio

Marco Picasso

An adaptive algorithm is proposed for solving the Stokes problem with continuous, piecewise linear stabilized finite elements and meshes with high aspect ratio. Anisotropic, a posteriori error estimates in the H-1 x L-2 norm are derived, the constant being ...

Numerical simulation of free surface incompressible liquid flows surrounded by compressible gas

Alexandre Caboussat, Marco Picasso, Jacques Rappaz

A numerical model for the three-dimensional simulation of liquid-gas flows with free surfaces is presented. The incompressible Navier-Stokes equations are assumed to hold in the liquid domain. In the gas domain, the velocity is disregarded, the pressure is ...
