Simulation of a Kelvin-Helmholtz instability using the Riemann difference scheme

For some of our recent work (@WillT @fdw) in shock-capturing, we’ve tested out a high-order version of our Riemann Difference (RD) scheme on a Kelvin-Helmholtz instability. Here’s a snapshot of the results.

Nice, how many degrees of freedom was this one in the end?

It was 67 million DoFs
