| # Dataset Card |
|  |
|
|
| This dataset contains a single huggingface split, named 'all_samples'. |
| |
| The samples contains a single huggingface feature, named called "sample". |
| |
| Samples are instances of [plaid.containers.sample.Sample](https://plaid-lib.readthedocs.io/en/latest/autoapi/plaid/containers/sample/index.html#plaid.containers.sample.Sample). |
| Mesh objects included in samples follow the [CGNS](https://cgns.github.io/) standard, and can be converted in |
| [Muscat.Containers.Mesh.Mesh](https://muscat.readthedocs.io/en/latest/_source/Muscat.Containers.Mesh.html#Muscat.Containers.Mesh.Mesh). |
| |
| |
| Example of commands: |
| ```python |
| from datasets import load_dataset |
| from plaid.bridges.huggingface_bridge import huggingface_dataset_to_plaid |
|
|
| hf_dataset = load_dataset("PLAID-datasets/2D_ElastoPlastoDynamics", split="all_samples") |
|
|
| dataset, problem = huggingface_dataset_to_plaid(hf_dataset, processes_number = 4) |
| |
| ids_train = problem.get_split('train') |
| ids_test = problem.get_split('test') |
| |
| sample_train_0 = dataset[ids_train[0]] |
| sample_test_0 = dataset[ids_test[0]] |
| |
| |
| # time steps |
| time_steps = sample_train_0.get_all_mesh_times() |
| |
| # inputs |
| nodes = sample_train_0.get_nodes() |
| elements = sample_train_0.get_elements() |
| |
| # outputs |
| for time in time_steps: |
| for fn in ['U_x', 'U_y']: |
| field = sample_train_0.get_field(fn, time = time) |
| |
| field = sample_train_0.get_field('EROSION_STATUS', location="CellCenter", time = time) |
| ``` |

| ## Dataset Details |
|
|
| ### Dataset Description |
|
|
|
|
| This dataset contains 2D dynamic non-linear structural mechanics with a non-linear non-local constitutive law. |
|
|
| The variablity in the samples is the geometry (mesh). Outputs of interest are 3 transient fields: x and y components of the displacement at the nodes and the erosion status at the elements. |
|
|
