Dec 13, 2014 at 9:30 comment added user136475 Thank you for answering. I know that the central differences with explicit Euler in time is unconditionally unstable, but there are other methods like Lax-Wendroff, Beam-Warming that are second order and stable for some CFL condition. So, this must mean that the DG-method above is a central difference scheme essentially, but I don't find it very transparent. But, essentially changing to Heun's method would then be stable I assume. How can I check the stability via von Neumann analysis? I am used to FD-schemes and going to FV- or DG-schemes is not straight-forward.
