Discrete filtering of numerical solutions to hyperbolic conservation laws
In the framework of finite volume approximations to the Euler equations of gas dynamics we introduce computationally cheap difference schemes in addition with efficient discrete filter operators correcting discrete values locally. After presentation of a classical discrete filter algorithm we describe for the first time the implementation of a TV filter, originally developed in signal and image processing, in the context of hyperbolic conservation laws on unstructured grids.
