The scheme

  • B. Perthame and C. Simeoni, A kinetic scheme for the Saint-Venant system with a source term, Calcolo 38(4), 201–231 (2001). hal-00922664. The scheme implemented here: kinetic formulation, interface densities with reflections, properties (Theorem 3.2) and closed-form fluxes (Section 4).

Analysis

  • M. Ersoy, Perthame–Simeoni kinetic traces and nonconservative interface laws for DG approximations of the Saint–Venant system, preprint (2026). hal-05618693. Discontinuous Galerkin interpretation of the scheme; exact momentum interface law (Proposition 4.1), tested in this code; the finite volume scheme is the case of polynomial degree 0.
