Same 144 × 60 grid and physical model. GPU calculations use 32-bit arithmetic; WASM uses 64-bit. This page measures accuracy and completed-step throughput. WebGPU is the default when available, with WASM as the automatic fallback. The GPU solver uses parallel pressure elimination and batches stability-limited timesteps. Accuracy checks cover the full 10 m/s wind range.
Pause other simulations before measuring. Benchmarks exclude initialization and rendering, include GPU completion/readback and worker coordination, and run the engines sequentially.
