This Week in CFD

Rayleigh-Benard ConvectionWhile it’s not for me to tell you what to watch or read, there are two must watch videos this week. The first – screenshot shown here – is a beautiful simulation of Rayleigh-Benard convection. The second is an article with embedded video interviews about our friend democratization and what it really means.

Meshing Uber Alles

From the “you never know who’s generating meshes” category – or at least doing tiling – the folks at Uber Engineering use a hexagonal tiling to map the globe, countries, states, and cities to optimize ride pricing geographically. Their software, H3, was recently released on GitHub if you care to give it a try.

Why hexagons? They minimize quantization error.
