A low Mach two-speed relaxation scheme for the compressible Euler equations with gravity
Claudius Birke, Christophe Chalons, Christian Klingenberg
We present a numerical approximation of the solutions of the Euler equations with a gravitational source term. On the basis of a Suliciu type relaxation model with two relaxation s…

On the Active Flux scheme for hyperbolic PDEs with source terms
Wasilij Barsukow, Jonas P. Berberich, Christian Klingenberg
The Active Flux scheme is a Finite Volume scheme with additional point values distributed along the cell boundary. It is third order accurate and does not require a Riemann solver:…
