Fluids-2D
Real-time 2D fluid dynamics simulation running on GPU via WebGL and Three.js.
What is Fluids-2D?
Fluids-2D is a real-time 2D fluid dynamics simulation that runs in web browsers using GPU acceleration via WebGL and Three.js. It solves the Navier-Stokes equations to simulate incompressible, homogeneous fluids, allowing for interactive visualizations and experiments without requiring native applications.
Developers, researchers, and educators interested in real-time physics simulations, fluid dynamics visualization, or WebGL-based computational projects.
It provides an accessible, browser-based platform for GPU-accelerated fluid simulations, eliminating the need for complex native setups while offering interactive, real-time performance through modern web technologies.

Pros & Cons
Pros
Uses WebGL to run fluid simulations entirely on the GPU, enabling smooth, interactive visualizations as highlighted in the demo, though it requires dedicated graphics hardware.
Built with Three.js and WebGL, it eliminates the need for native installations, making it easy to deploy and share simulations directly in web browsers.
Provides a live web interface for manipulating fluid flows, ideal for demonstrations and experiments in learning or prototyping scenarios.
Based on established references like Jos Stam's work, ensuring a robust foundation in solving Navier-Stokes equations for incompressible fluids.
Cons
The README notes performance issues on integrated graphics cards, limiting accessibility for users without dedicated GPUs.
Assumes incompressible, homogeneous fluids, which may not accurately model real-world complexities like compressibility or varying densities.
Focuses solely on 2D fluid dynamics, making it unsuitable for applications requiring three-dimensional visualization or analysis.
