Free Unity 6 Project: StableFluids GPU Fluid Simulation (Keijiro)

Overview

StableFluids is Keijiro Takahashi's straightforward GPU implementation of Jos Stam's 'Stable Fluids' algorithm in Unity, maintained for Unity 6 (6000.0) on URP. The simulation runs in compute shaders using render textures, and the project ships with an interactive demo in which an image is advected by the fluid as you interact with it.

It is published on GitHub under the Unlicense (public domain), so it can be reused without restriction. Ideal for learning compute-shader fluid solvers or building interactive visual effects, and small enough that the whole solver can be read in an afternoon.
