Evaluation of model performance on solving the 2-D Burgers Partial Differential Equation under an out-of-distribution shift, specifically testing resolution changes from $64^2$ to $128^2$ on the test set.

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 | Solving 2-D Burgers equation |
| Dataset (including any stated split) | 2-D Burgers Out-of-Distribution resolution 64^2 to 128^2 shift (test) |
| Metric | OOD Error |
| Unit | SCALAR |
| Direction | Lower is better |
| Results loaded | 5 of 5 |
| 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

- [OOD Error](<https://www.sota2.com/research/sota/solving-2-d-burgers-equation-on-2-d-burgers-out-of-distribution-resolution-64-2-to-128-2-shift-test.md?metric=OOD%20Error>): Lower is better; unit: SCALAR.

- [OOD Inference Time (s)](<https://www.sota2.com/research/sota/solving-2-d-burgers-equation-on-2-d-burgers-out-of-distribution-resolution-64-2-to-128-2-shift-test.md?metric=OOD%20Inference%20Time%20(s)>): Lower is better; unit: TIME.
