Rotor37: a 3D CFD RANS dataset, under geometrical variations of a compressor blade

This dataset contains 3D CFD RANS solutions, under geometrical variations of a compressor blade.

A Description is provided in 2305.12871.pdf (arxiv.org) Sections 4.1 and Appendix A.1.

The file format is PLAID, see the plaid documentation.

The variablity in the samples are 2 input scalars and the geometry (mesh). Outputs of interest are 3 scalars and 3 fields.

Eight nested training sets of sizes 8 to 1000 are provided, with complete input-output data. A testing set of size 200 is provided, for which outputs are not provided.  

Tips to access the data:

After decompressing the downloaded file:

from plaid.containers.dataset import Datasetfrom plaid.problem_definition import ProblemDefinition

dataset = Dataset()problem = ProblemDefinition()

problem._load_from_dir_(os.path.join(/path/to/data,'problem_definition'))dataset._load_from_dir_(os.path.join(/path/to/data,'dataset'), verbose = True)

print("problem =", problem)print("dataset =", dataset)

sample = dataset[0]print("sample =", sample)

for fn in sample.get_field_names():    print(f"{fn} =", sample.get_field(fn))for sn in sample.get_scalar_names():    print(f"{sn} =", sample.get_scalar(sn))

print("nodes =", sample.get_nodes())print("elements =", sample.get_elements())
