Abstract
The present paper deals with the multi-dimensional limiting process (MLP) for arbitrary higher-order discontinuous Galerkin (DG) methods to
compute compressible inviscid and viscous flows. MLP, which has been quite
successful in finite volume methods (FVM), is extended into DG methods for
hyperbolic conservation laws. We firstly formulate the robust and accurate hierarchical MLP limiting strategy for DG-P n(n 2) reconstruction. Secondly,
the resulting method, called the DG-MLP method, is applied to various inviscid and viscous flows. In the final paper, detailed numerical procedure for
the hierarchical DG-MLP formulation and extensive numerical test cases to
demonstrate its numerical accuracy and robustness will be given.
