Dissipation-dispersion analysis of fully-discrete implicit discontinuous Galerkin methods and application to stiff hyperbolic problems
Maya Briani, Gabriella Puppo, Giuseppe Visconti
The application of discontinuous Galerkin (DG) schemes to hyperbolic systems of conservation laws requires a careful interplay between space discretization, carried out with local…
Quinpi: Integrating stiff hyperbolic systems with implicit high order finite volume schemes
Gabriella Puppo, Matteo Semplice, Giuseppe Visconti
Many interesting physical problems described by systems of hyperbolic conservation laws are stiff, and thus impose a very small time-step because of the restrictive CFL stability c…
An all Mach number finite volume method for isentropic two-phase flow
Maria Lukacova-Medvid'ova, Gabriella Puppo, Andrea Thomann
We present an implicit-explicit finite volume scheme for isentropic two phase flow in all Mach number regimes. The underlying model belongs to the class of symmetric hyperbolic the…
Angle dependence in coupling conditions for shallow water equations at canal junctions
Maya Briani, Gabriella Puppo, Magali Ribot
In this paper we propose a numerical Riemann problem solver at the junction of one dimensional shallow-water canal networks. The junction conditions take into account the angles wi…
One- and multi-dimensional CWENOZ reconstructions for implementing boundary conditions without ghost cells
M. Semplice, E. Travaglia, G. Puppo
We address the issue of point value reconstructions from cell averages in the context of third order finite volume schemes, focusing in particular on the cells close to the boundar…
An all speed second order well-balanced IMEX relaxation scheme for the Euler equations with gravity
Andrea Thomann, Gabriella Puppo, Christian Klingenberg
We present an implicit-explicit well-balanced finite volume scheme for the Euler equations with a gravitational source term which is able to deal also with low Mach flows. To visua…
