Evaluation of model performance on predicting the flow field for the HCSG tube bundle dataset under 0.4 m/s inlet velocity conditions (test split), measured by point-wise metrics P1 through P6.

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) | HCSG tube bundle 0.4 m/s inlet velocity (test) |
| Metric | Point-wise Metric P1 |
| Unit | SCALAR |
| Direction | Lower is better |
| Results loaded | 4 of 4 |
| 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.
