Environment import from open street map#

This example shows how to use PyAEDT to create an HFSS SBR+ project from OpenStreetMap.

Keywords: HFSS, SBR+, city, OpenStreetMap

Prerequisites#

Perform imports#

[ ]:

import tempfile
import time
from pathlib import Path

import ansys.aedt.core
from ansys.aedt.core.generic.settings import settings

Define constants#

Constants help ensure consistency and avoid repetition throughout the example.

[ ]:

AEDT_VERSION = "2026.1"
NG_MODE = False  # Open AEDT UI when it is launched.

Create temporary directory#

Create a temporary working directory. The name of the working folder is stored in temp_folder.name.

Note: The final cell in the notebook cleans up the temporary folder. If you want to retrieve the AEDT project and data, do so before executing the final cell in the notebook.

[ ]:

temp_folder = tempfile.TemporaryDirectory(suffix=".ansys")

Launch HFSS and open project#

Launch HFSS and open the project.

[ ]:

project_name = Path(temp_folder.name) / "city.aedt"
app = ansys.aedt.core.Hfss(
    project=str(project_name),
    design="Ansys",
    solution_type="SBR+",
    version=AEDT_VERSION,
    new_desktop=True,
    non_graphical=NG_MODE,
)

Model Preparation#

Define the global location#

Define the latitude and longitude of the location to import from OpenStreetMap.

[ ]:

ansys_home = [40.273726, -80.168269]

Generate map and import#

Import the model and define the domain size. The radius that defines the domain is specified in meters.

[ ]:

# Disabling default release on exception as importing data from openstreet map can raise an exception.
settings.release_on_exception = False
app.modeler.import_from_openstreet_map(
    ansys_home,
    terrain_radius=250,
    road_step=3,
    plot_before_importing=False,
    import_in_aedt=True,
)
# Reverting back to release on exception.
settings.release_on_exception = True

Visualize the model#

Plot the model.

[ ]:

plot_obj = app.plot(show=False, plot_air_objects=True)
plot_obj.background_color = [153, 203, 255]
plot_obj.zoom = 1.5
plot_obj.show_grid = False
plot_obj.show_axes = False
plot_obj.bounding_box = False
plot_obj.plot(Path(temp_folder.name) / "Source.jpg")

Finish#

Save the project#

Release AEDT and close the example.

[ ]:

app.save_project()
app.release_desktop()
# Wait 3 seconds to allow AEDT to shut down before cleaning the temporary directory.
time.sleep(3)

Clean up#

All project files are saved in the folder temp_folder.name. If you’ve run this example as a Jupyter notebook, you can retrieve those project files. The following cell removes all temporary files, including the project folder.

[ ]:

temp_folder.cleanup()
