Heuristical and numerical considerations for the carbuncle phenomenon

Computational Physics 2017-03-07 v2 Numerical Analysis

Abstract

In this study, we investigate the so called carbuncle phenomenon by means of numerical experiments and heuristic considerations. We identify two main sources for the carbuncle: instability of the 1d shock position and low numerical viscosity on shear waves. We also describe how higher order stabilizes the 1d shock position and, thus, reduces the carbuncle.
