A 2D Fluid Simulator made in Godot 3.4.4, running on the GPU through Godot’s shader language. It attempts to solve the Navier-Stokes equation in real time by taking advantage of the parallelism of GPU’s.

For further details, check out this post: https://godotforums.org/discussion/29164/2d-fluid-simulation/

Please share your feedback and suggestions. I’m especially hopeful there are still improvements to be made to the technical side of the simulation.
