Name: lattice
Title: Lattice
Kind: Wind tunnel, GPU
Status: Running
Created: 2025-02-13 (627d ago)
Built With: C, OpenGL 4.3, Next.js, Modal, AWS
Highlights:
- D3Q19 Lattice Boltzmann solver in OpenGL 4.3 compute shaders
- 30k particles with spatial-grid-accelerated per-triangle mesh collision
- Drag and lift within 8% of published Ahmed body wind tunnel benchmarks
- Headless EGL renders on Modal (A10G), live convergence plots, browser-side ML surrogate for instant Cd
Note: Paired with a preprint: differentiable D3Q19 in JAX, geometry gradients to <1e-9 relative error.
