Dear Foamers,
I developed an OpenFOAM solver for the simulation of the deflagration-to-detonation transition in gases.
Some features:

• accurate shock capturing with a density based solver (largely based on Oliver Borm's development densityBasedTurbo)
• deflagration modelling via a reaction progress variable (based on XiFoam)
• auto-ignition sub-grid model separating each computational cell into a "shocked" and an "unshocked" part
• auto-ignition from tabulated ignition delay times, gained from a detailed chemical mechanism
• low computational cost due to applicability to coarse grids and usage of pre-tabulated chemistry

Even if you're not interested in detonations/combustion, it might be a nice alternative to existing OpenFOAM solvers when it comes to shock resolution in transonic flows.

The code incl. a short documentation and tutorials can be downloaded from
