Implicit relaxed all Mach number schemes for gases and compressible materials
Andrea Thomann, Angelo Iollo, Gabriella Puppo
We present an implicit relaxation scheme for the simulation of compressible flows in all Mach number regimes based on a Jin Xin relaxation approach. The main features of the propos…
Model of vehicle interactions with autonomous cars and its properties
M. Herty, G. Puppo, G. Visconti
We study a hierarchy of models based on kinetic equations for the descriptions of traffic flow in presence of autonomous and human--driven vehicles. The autonomous cars considered…
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…
Quinpi: integrating conservation laws with CWENO implicit methods
G. Puppo, M. Semplice, G. Visconti
Many interesting applications of hyperbolic systems of equations are stiff, and require the time step to satisfy restrictive stability conditions. One way to avoid small time steps…
