PLAID-datasets/2D_ElastoPlastoDynamics

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. Mesh objects included in samples follow the CGNS standard, and can be converted in Muscat.Containers.Mesh.Mesh.

Example of commands:

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.

Dataset created using the PLAID library and datamodel, version 0.1.
