How it works
Each cell of a 256×256 density field is updated by a WGSL compute shader that traces the flow backward in time (semi-Lagrangian advection) and samples the previous frame with bilinear interpolation, then a fullscreen fragment shader renders it — a full GPU compute+render loop with ping-pong storage buffers. This is the browser doing the kind of grid simulation that used to require a desktop and a dedicated GPU toolkit.

Ask the AI about this model
The math, the assumptions, real-world uses, or a code translation — explained for this exact simulation.
Yes. WebGPU Fluid runs entirely in your browser using your device's own compute, so local use is free forever. You only pay Compute Tokens if you scale a job to the cloud.
Do I need to install anything?▾
No. Everything runs client-side in a modern browser — no downloads, no license, no account required to start.
Can I save or share my simulation?▾
Create a free account to save projects, and use a shareable embed or minted DOI to publish a live, interactive version anywhere.
How accurate are the results?▾
The solver uses established numerical methods, but results are for research and educational purposes and should be validated against experiment or professional review before you rely on them.
