Navier-Stokes fluid simulation explained with Godot game engine
Summary
An in-depth, code-heavy tutorial that explains grid-based Navier-Stokes fluid simulation in Godot. It covers density and velocity fields, advection, diffusion via Gauss-Seidel, boundary handling, velocity projection for incompressibility, and interactive exploration with mouse input. The post references Stam’s work and includes open-source code snippets and GitHub project links.
