On the numerical overshoots of shock‐capturing schemes [PDF]

open access: yesInternational Journal for Numerical Methods in Fluids, 2021
AbstractThis note introduces a simple metric for benchmarking shock‐capturing schemes. This metric is especially focused on the shock‐capturing overshoots, which may undermine the robustness of numerical simulations, as well as the reliability of numerical results.

Entropy Stable DGSEM Schemes of Gauss Points Based on Subcell Limiting

open access: yesEntropy, 2023
The discontinuous Galerkin spectral element method (DGSEM) is a compact and high-order method applicable to complex meshes. However, the aliasing errors in simulating under-resolved vortex flows and non-physical oscillations in simulating shock waves may

An Improved Component-Wise WENO-NIP Scheme for Euler System

open access: yesMathematics, 2022
As is well known, due to the spectral decomposition of the Jacobian matrix, the WENO reconstructions in the characteristic-wise fashion (abbreviated as CH-WENO) need much higher computational cost and more complicated implementation than their ...

Nonconservative Hybrid Shock Capturing Schemes [PDF]

open access: yesJournal of Computational Physics, 1992
Hybrid schemes are suggested for a hyperbolic system of conservation laws based on the selection in each node of a difference grid of a suitable approximation of equations via constructed analyzers of the solution smoothness. In the smooth regions, the solution is obtained by easily realized high-order systems based on Runge-Kutta methods with the ...
