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…
