CFD

Proposes a Runge-Kutta aligned oscillation-eliminating DG framework that fixes the disruption of error structures caused by nonlinear stabilization, enabling superconvergence analysis for fully discrete shock-capturing DG schemes.

CFD

Proposes a subcell-refined entropy-residual-driven limiter for high-order DG methods on Legendre-Gauss-Lobatto nodes, enabling robust simulation of under-resolved nonlinear hyperbolic systems while preserving accuracy via nearest-neighbor pairwise dissipation.
