Multi blade row meshing example

This basic example shows how to set up a multi blade row meshing instance and execute it in parallel.

Perform required imports

Perform the required imports. It is assumed that the ansys-turbogrid-core package has been installed.

import os
import pathlib

from ansys.turbogrid.core.multi_blade_row.multi_blade_row_batch import MultiBladeRow

Create and use a MultiBladeRow instance

Create a MultiBladeRow instance, set it up for a multi blade row case and execute.

if __name__ == "__main__":
    # Set working directory.
    working_directory = os.getcwd()

    # NDF file for this example.

    ndf_file_name = "AxialFanMultiRow.ndf"

    # Build the path to the test data folder
    test_data_path = pathlib.PurePath(__file__).parent.parent.as_posix()
    test_data_path = os.path.join(test_data_path, "tests")
    test_data_path = os.path.join(test_data_path, "ndf")

    # Create a MultiBladeRow instance.
    mbr_instance = MultiBladeRow(working_directory, test_data_path, ndf_file_name)

    # Set up some settings.
    mbr_instance.set_spanwise_counts(56, 73)
    mbr_instance.set_global_size_factor(1.5)
    mbr_instance.set_blade_boundary_layer_offsets(6e-6)
    mbr_instance.write_tginit_first = True

    # Call the execute method to perform the meshing.
    mbr_instance.execute()
