Heuristical and numerical considerations for the carbuncle phenomenon
Friedemann Kemm
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: ins…
Roe-type schemes for shallow water magnetohydrodynamics with hyperbolic divergence cleaning
Friedemann Kemm
We discuss Roe-type linearizations for non-conservative shallow water magnetohydrodynamics without and with hyperbolic divergence cleaning.
On the Proper Setup of the Double Mach Reflection as a Test Case for the Resolution of Gas Dynamics Codes
Friedemann Kemm
This note discusses the initial and boundary conditions as well as the size of the computational domain for the double Mach reflection problem when set up as a test for the resolut…
A note on the carbuncle in shallow water simulations
Friedemann Kemm
An important problem in gas dynamics simulation is to prevent the carbuncle, a breakdown of discrete shock profiles. We show that for high Froude number, this also occurs in shallo…
