# U

We study the "U" files in OpenFOAM tutorials. The results can be obtained by running

```sh
cd dev/study_OF_examples
./study_1_filename.py U check
# or (faster)
./study_1_filename.py U
```

Here are the results:

```
nb_examples = 369
{'Empty file': 38, 'parser error': 0, 'wrong files': 3}

{
 'dimensions': 328,
 'boundaryField': 328,

No parser issue for U!
