A discontinuous Galerkin overset scheme using WENO reconstruction and subcells for two-dimensional problems
S R Siva Prasad Kochi, M Ramakrishna
A new scheme for communication between overset grids using subcells and Weighted Essentially Non Oscillatory (WENO) reconstruction for two-dimensional problems has been proposed. T…

A compact subcell WENO limiting strategy using immediate neighbors for Runge-Kutta discontinuous Galerkin methods for unstructured meshes
S R Siva Prasad Kochi, M Ramakrishna
In this paper, we generalize the compact subcell weighted essentially non oscillatory (CSWENO) limiting strategy for Runge-Kutta discontinuous Galerkin method developed recently by…
