Quick Start Example

# pylint: disable=pointless-statement
from pathlib import Path
import numpy as np
from mesh2vec.mesh2vec_cae import Mesh2VecCae

Load Shell from ANSA

m2v = Mesh2VecCae.from_ansa_shell(
    4,
    Path("../../data/hat/Hatprofile.k"),
    json_mesh_file=Path("../../data/hat/cached_hat_key.json"),
)

Add element features

m2v.add_features_from_ansa(
    ["aspect", "warpage"],
    Path("../../data/hat/Hatprofile.k"),
    json_mesh_file=Path("../../data/hat/cached_hat_key.json"),
)

['aspect', 'warpage']

Aggregate

m2v.aggregate("aspect", [0, 2, 3], np.nanmean)

['aspect-nanmean-0', 'aspect-nanmean-2', 'aspect-nanmean-3']

Extract Feature Vector

m2v.to_dataframe()
