Been working on this for a while now. It's a finite-volume solver for the compressible Euler/Navier-Stokes equations on unstructured meshes, written in C with MPI parallelism. The video shows the flow around a sphere at Mach 0.3, Re 1000.

The numerics are quite standard, but I think what sets it apart is that it can partition and redistribute the domain across MPI ranks at runtime, and can restart a simulation onto a completely different mesh.
