Configuration files#

This example shows how to use PyAEDT to export configuration files and reuse them to import in a new project. A configuration file is supported by these applications:

  • HFSS

  • 2D Extractor and Q3D Extractor

  • Maxwell

  • Icepak (in AEDT)

  • Mechanical (in AEDT)

The following topics are covered:

  • Variables

  • Mesh operations (except Icepak)

  • Setup and optimetrics

  • Material properties

  • Object properties

  • Boundaries and excitations

When a boundary is attached to a face, PyAEDT tries to match it with a FaceByPosition on the same object name on the target design. If for any reason this face position has changed or the object name in the target design has changed, the boundary fails to apply.

Keywords: AEDT, general, configuration file, setup.

Perform imports and define constants#

Import the required packages.

[1]:

import os
import tempfile
import time

import ansys.aedt.core

Define constants.

[2]:

AEDT_VERSION = "2024.2"
NG_MODE = False  # Open AEDT UI when it is launched.

Create temporary directory#

Create the temporary directory. If you’d like to retrieve the project data for subsequent use, the temporary folder name is given by temp_folder.name.

[3]:

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

Download project#

Download the Icepack project.

[4]:

project_full_name = ansys.aedt.core.downloads.download_icepak(
    destination=temp_folder.name
)

Open project#

Open the Icepak project from the project folder.

[5]:

ipk = ansys.aedt.core.Icepak(
    project=project_full_name,
    version=AEDT_VERSION,
    new_desktop=True,
    non_graphical=NG_MODE,
)
ipk.autosave_disable()

setup1 = ipk.create_setup()
setup1["FlowRegime"] = "Turbulent"
setup1["Max Iterations"] = 5

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.
