Basic Mesh Generation

This example demonstrates how to launch PyTurboGrid, load a blade model by reading an inf file, and generate a mesh. The example also demonstrates how to query mesh statistics for the mesh.

import json
import os.path as ospath

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

from ansys.turbogrid.core.launcher.launcher import get_turbogrid_exe_path, launch_turbogrid

Launch a TurboGrid instance in the most basic way.

turbogrid = launch_turbogrid()

Find the examples folder based on the path to the TurboGrid executable found by the call below to get_turbogrid_exe_path. This ensures that the examples folder from the current TurboGrid installation is used.

exec_path = get_turbogrid_exe_path()
turbogrid_install_location = "/".join(exec_path.parts[:-2])
turbogrid_install_location = turbogrid_install_location.replace("\\", "")
examples_path_str = turbogrid_install_location + "/examples"

Ensure the examples folder exists.

if not ospath.isdir(examples_path_str):
    print("examples folder not found in the TurboGrid installation")
    exit()

Read the BladeGen *.inf file for the rotor37 example.

turbogrid.read_inf(examples_path_str + "/rotor37/BladeGen.inf")

Generate a mesh with the default settings.

turbogrid.unsuspend(object="/TOPOLOGY SET")

Get the mesh statistics from the current session.

stats = turbogrid.query_mesh_statistics()

Print out the mesh statistics in a format suitable for reading. json serializer can print nested dictionary content with indentation and formatting.

print("Mesh statistics:", json.dumps(stats, indent=2))

Save the mesh.

turbogrid.save_mesh(filename="rotor37.gtm")

Quit the TurboGrid session.

turbogrid.quit()
