Since the development of shock‐capturing methods, the carbuncle phenomenon has been reported to be a spurious solution produced by almost all currently available contact‐preserving methods. The present analysis indicates that the onset of carbuncle phenomenon is actually strongly related to the shock wave numerical structure. A matrix‐based stability analysis as well as Euler finite volume computations are compared to illustrate the importance of the internal shock structure to trigger the carbuncle phenomenon.
