Navier-Stokes fluid simulation explained with Godot game engine | Hacker News

A Hacker News post shared a detailed tutorial on building fluid simulation in Godot using Navier-Stokes methods.

The author said the guide came out of a two-month learning project, making a complex graphics topic more approachable for developers and hobbyists.

Commenters praised the writeup, recommended Robert Bridson’s *Fluid Simulation for Computer Graphics*, and flagged a timestep issue in the rocket exhaust velocity code.
