An Active Flux method for the Euler equations based on the exact acoustic evolution operator
A new Active Flux scheme for the 2D Euler equations combines an exactly solved locally linearized acoustic operator with a third-order advective evolution operator inside an additive splitting, using primitive variables and bound-preserving limiting.
