Modeling and simulating the spatial spread of an epidemic through multiscale kinetic transport equations
Walter Boscheri, Giacomo Dimarco, Lorenzo Pareschi
In this work we propose a novel space-dependent multiscale model for the spread of infectious diseases in a two-dimensional spatial context on realistic geographical scenarios. The…
Simulation of non-Newtonian viscoplastic flows with a unified first order hyperbolic model and a structure-preserving semi-implicit scheme
Ilya Peshkov, Michael Dumbser, Walter Boscheri +3
We discuss the applicability of a unified hyperbolic model for continuum fluid and solid mechanics to modeling non-Newtonian flows and in particular to modeling the stress-driven s…
Curl constraint-preserving reconstruction and the guidance it gives for mimetic scheme design
Dinshaw S. Balsara, Roger Käppeli, Walter Boscheri +1
Several important PDE systems, like magnetohydrodynamics and computational electrodynamics, are known to support involutions where the divergence of a vector field evolves in diver…
High order pressure-based semi-implicit IMEX schemes for the 3D Navier-Stokes equations at all Mach numbers
Walter Boscheri, Lorenzo Pareschi
This article aims at developing a high order pressure-based solver for the solution of the 3D compressible Navier-Stokes system at all Mach numbers. We propose a cell-centered disc…
A structure-preserving staggered semi-implicit finite volume scheme for continuum mechanics
Walter Boscheri, Michael Dumbser, Matteo Ioriatti +2
We propose a new pressure-based structure-preserving (SP) and quasi asymptotic preserving (AP) staggered semi-implicit finite volume scheme for the unified first order hyperbolic f…
