# Wind tunnel Read `studio.json` to understand the current controls; `"$STUDIO_TOOLCHAIN/../studio.config.json"` describes their ranges. Run `"$STUDIO_TOOLCHAIN/run.sh" simulate` to make a new result. Successful artifacts and their measurements are in `out/runs/<id>/`; `out/latest.json` names the current result. A failed run preserves the last success and records the error in the verdict. The local workflow solves a two-dimensional D2Q9 lattice Boltzmann model on a coarse grid. It is an exploratory simulation, not a converged engineering drag analysis. The optional OpenFOAM action reproduces the supplied lid-driven cavity benchmark; Foam-Agent instructions and sources are pinned for richer cases. Use `"$STUDIO_TOOLCHAIN/../README.md"` for the integration contract and commands. Read the relevant files under `$STUDIO_UPSTREAM` before using an upstream API. Keep controls within their documented ranges, preserve the data needed to reproduce a comparison, and distinguish preview results from native service or hardware output. The viewer supports history and artifact downloads; tell the user which run contains the result, and what was actually measured. ## Compare flow cases Save a baseline, then vary shape or radius while holding inlet speed, viscosity, and solver steps fixed. Read `flow.csv` and `field.json`; check finite velocities, solid-boundary velocities, and the convergence record. A coarse flow picture does not establish drag or mesh convergence.
