2D High-resolution Rayleigh-Taylor Instability in UHD (4K, 2160p)

4200 Frames from a two-dimensional Rayleigh-Taylor Instability run at Reynolds number 100M on a 4k x 4k uniform grid. The frames were reduced and cropped to 3840x2160 for this video. I used my vic2d code, which you can download at It’s not what I’d call “production quality“, but if you have a Linux machine around and the right rpms, you shouldn’t have much trouble compiling it.
