A new efficient formulation of the HLLEM Riemann solver for general conservative and non-conservative hyperbolic systems
New simple and general path-conservative formulation of the HLLEM Riemann solver. Application to general conservative and non-conservative hyperbolic systems. Inclusion of sub-structure and resolution of intermediate characteristic fields. Well-balanced for single- and two-layer shallow water equations and multi-phase flows. Euler equations with real equation of state, MHD equations, nonlinear elasticity.
