Johannes Brandstetter on why numerical choices in turbulence simulation matter for AI4Science training data

Johannes Brandstetter started a thread on turbulence aimed at the AI4Science community. He presents the Navier–Stokes equations and notes turbulence is ubiquitous—it mixes oceans and carries heat through the atmosphere.

His key point: numerical choices heavily impact the characteristics of simulated turbulence, and this matters because the community uses these simulated flows to train and evaluate its models.
