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.containers.sample import Sample
import pickle

# Load the dataset
hf_dataset = load_dataset("PLAID-datasets/2D_ElastoPlastoDynamics", split="all_samples")

# Get split ids
ids_train = hf_dataset.description["split"]['train']
ids_test  = hf_dataset.description["split"]['test']

# Get inputs/outputs names
in_scalars_names = hf_dataset.description["in_scalars_names"]
out_fields_names = hf_dataset.description["out_fields_names"]

# Get samples
sample = Sample.model_validate(pickle.loads(hf_dataset[ids_train[0]]["sample"]))
sample_2 = Sample.model_validate(pickle.loads(hf_dataset[ids_test[0]]["sample"]))

# Examples data retrievals
# time steps
time_steps = sample.get_all_mesh_times()

# inputs
nodes = sample.get_nodes()
elements = sample.get_elements()

# outputs
for time in time_steps:
    for fn in [`U_x` and `U_y`]:
        field = sample.get_field(fn, time = time)

    field = sample.get_field(`EROSION_STATUS`, location="CellCenter", time = time)

# Get the mesh and convert it to Muscat
from Muscat.Bridges import CGNSBridge
CGNS_tree = sample.get_mesh(time = 0.)
mesh = CGNSBridge.CGNSToMesh(CGNS_tree)
print(mesh)

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.
