Snapshot: A high order detonation diffraction simulation with reactive Euler equations

We show a detonation diffraction simulation with multiple obstacles in a reflective box using reactive multicomponent Euler equations with Trixi.jl. These kind of detonation waves may result in pressure and density drops close to zero which is numerically difficult not only but especially for high order schemes.

In this simulation we use a reacting model which consists of one reaction and two species. This example has been calculated using the high order DG-FV blending method in Trixi.jl with a HOHQMesh generated mesh whereas the chemical network is solved with KROME.

(Note: Not all of these features are currently available in the main code of Trixi.jl.)
