A posteriori subcell limiting of the discontinuous Galerkin finite element method for hyperbolic conservation laws
A posteriori subcell limiter for arbitrary high order DG schemes in space and time. Simple a posteriori troubled zones indicator. The new limiter maintains the DG subgrid resolution capability even at discontinuities. Troubled zones are recomputed with ADER-WENO finite volume scheme on the subgrid. HPC simulations in 3D with P9 elements and 10 billion degrees of freedom.
