Evaluation of flow field prediction performance on the CFDBench Cavity dataset, measured using RMSE, Vorticity (Vor), Spectral Energy (Spec), and Divergence (Div) metrics.

A research result applies to its stated dataset, split, metric and evaluation configuration. Compare like-for-like settings, preserve the metric's unit and direction, and distinguish paper-reported results from independent reproduction. The best result recorded here is not a claim of exhaustive, current global coverage.

| Scope | Recorded value |
| --- | --- |
| Task | Flow Field Prediction |
| Dataset (including any stated split) | CFDBench Cavity |
| Metric | RMSE |
| Unit | SCALAR |
| Direction | Lower is better |
| Results loaded | 6 of 6 |
| Coverage | All results currently returned for this benchmark |

Evaluation settings may differ between results. The original papers and recorded configurations are needed to establish comparability. A shared metric name alone does not establish an identical protocol.

## Metrics

- [RMSE](<https://www.sota2.com/research/sota/flow-field-prediction-on-cfdbench-cavity.md?metric=RMSE>): Lower is better; unit: SCALAR.

- [Vorticity](<https://www.sota2.com/research/sota/flow-field-prediction-on-cfdbench-cavity.md?metric=Vorticity>): Lower is better; unit: SCALAR.

- [Spectral Energy](<https://www.sota2.com/research/sota/flow-field-prediction-on-cfdbench-cavity.md?metric=Spectral%20Energy>): Higher is better; unit: SCALAR.

- [Divergence](<https://www.sota2.com/research/sota/flow-field-prediction-on-cfdbench-cavity.md?metric=Divergence>): Lower is better; unit: SCALAR.
