PLAID-datasets/VKI-LS59

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:

# Get a sample
split_names = list(dataset.description["split"].keys())
print(split_names)
ids_split_0 = dataset.description["split"]['train']
sample_0_split_0 = dataset[ids_split_0[0]]["sample"]
plaid_sample = Sample.model_validate(pickle.loads(sample_0_split_0))
print("type(plaid_sample) =", type(plaid_sample))

print("plaid_sample =", plaid_sample)

# Access data from this sample
for fn in ["sdf", "ro", "rou", "rov", "roe", "nut", "mach"]:
    print(f"{fn} =", plaid_sample.get_field(fn, base_name="Base_2_2"))
print("M_iso =", plaid_sample.get_field("M_iso", base_name="Base_1_2"))
for sn in plaid_sample.get_scalar_names():
    print(f"{sn} =", plaid_sample.get_scalar(sn))

print("nodes 2D (flow) =", plaid_sample.get_nodes(base_name="Base_2_2"))
print("nodes 1D (blade surface) =", plaid_sample.get_nodes(base_name="Base_1_2"))
print("elements 2D (flow) =", plaid_sample.get_elements(base_name="Base_2_2"))
print("elements 1D (blade surface) =", plaid_sample.get_elements(base_name="Base_1_2"))
print("nodal_tags 2D (flow) =", plaid_sample.get_nodal_tags(base_name="Base_2_2"))

Dataset Details

Dataset Description

This dataset contains 2D internal aero CFD RANS solutions, under geometrical variations, based on the VKI-LS59 blade.

The variablity in the samples are 2 input scalars and the geometry (mesh) - the signed distance function is also provided and can be used as an input field. Outputs of interest are 7 fields (6 2D-fields and 1 1D-field) and 6 scalars.

Eight nested training sets of sizes 8 to 671 are provided, with complete input-output data. A testing set of size 168 is provided, for which outputs are not provided.

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