PLAID-datasets/Tensile2d

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/Tensile2d", split="all_samples")

# Get split ids
ids_train = hf_dataset.description["split"]['train_500']
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
# inputs
nodes = sample.get_nodes()
elements = sample.get_elements()
nodal_tags = sample.get_nodal_tags()

for sn in ['P', 'p1', 'p2', 'p3', 'p4', 'p5']:
    scalar = sample.get_scalar(sn)

# outputs
for fn in ['U1', 'U2', 'q', 'sig11', 'sig22', 'sig12']:
    field = sample.get_field(fn)

for sn in ['max_von_mises', 'max_q', 'max_U2_top', 'max_sig22_top']:
    scalar = sample.get_scalar(sn)

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

Dataset Details

Dataset Description

This dataset contains 2D quasistatic non-linear structural mechanics solutions, under geometrical variations.

A description is provided in the MMGP paper Sections 4.1 and A.2.

The variablity in the samples are 6 input scalars and the geometry (mesh). Outputs of interest are 4 scalars and 6 fields.

Seven nested training sets of sizes 8 to 500 are provided, with complete input-output data. A testing set of size 200, as well as two out-of-distribution samples, are provided, for which outputs are not provided.

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