RKDG Methods with Multi-resolution WENO Limiters for Solving Steady-State Problems on Triangular Meshes
In this paper, we design high-order Runge-Kutta discontinuous Galerkin (RKDG) methods with multi-resolution weighted essentially non-oscillatory (multi-resolution WENO) limiters to compute compressible steady-state problems on triangular meshes. A troubled cell indicator extended from structured meshes to unstructured meshes is constructed to identify triangular cells in which the application of the limiting procedures is required. In such troubled cells, the multi-resolution WENO limiting methods are used to the hierarchical
RKDG method / Steady-state problem / Multi-resolution WENO limiter / Triangular mesh / Machine zero
