General: configuration files

This example shows how you can use PyAEDT to export configuration files and re-use 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 sections 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, the tool 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.

Perform required imports

Perform required imports from ansys.aedt.core.

import os
import ansys.aedt.core

Set AEDT version

Set AEDT version.

aedt_version = "2024.2"

Set non-graphical mode

Set non-graphical mode. You can set non_graphical either to True or False.

non_graphical = False

Open project

Download the project, open it, and save it to the temporary folder.

project_full_name = ansys.aedt.core.downloads.download_icepak(ansys.aedt.core.generate_unique_folder_name(folder_name="Graphic_Card"))

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

True

Create source blocks

Create a source block on the CPU and memories.

ipk.create_source_block(object_name="CPU", input_power="25W")
ipk.create_source_block(object_name=["MEMORY1", "MEMORY1_1"], input_power="5W")

<ansys.aedt.core.modules.boundary.BoundaryObject object at 0x0000020CD1C45810>

Assign boundaries

Assign the opening and grille.

region = ipk.modeler["Region"]
ipk.assign_openings(air_faces=region.bottom_face_x.id)
ipk.assign_grille(air_faces=region.top_face_x.id, free_area_ratio=0.8)

<ansys.aedt.core.modules.boundary.BoundaryObject object at 0x0000020CC80EDAB0>

Create setup

Create the setup. Properties can be set up from the setup object with getters and setters. They don’t have to perfectly match the property syntax.

setup1 = ipk.create_setup()
setup1["FlowRegime"] = "Turbulent"
setup1["Max Iterations"] = 5
setup1["Solver Type Pressure"] = "flex"
setup1["Solver Type Temperature"] = "flex"
ipk.save_project(r"C:\temp\Graphic_card.aedt")

True

Export project to step file

Export the current project to the step file.

filename = ipk.design_name
file_path = os.path.join(ipk.working_directory, filename + ".step")
ipk.export_3d_model(file_name=filename, file_path=ipk.working_directory, file_format=".step", assignment_to_export=[],
                    assignment_to_remove=[])

True

Export configuration files

Export the configuration files. You can optionally disable the export and import sections. Supported formats are json and toml files

conf_file = ipk.configurations.export_config(os.path.join(ipk.working_directory, "config.toml"))
ipk.close_project()

True

Create project

Create an Icepak project and import the step.

app = ansys.aedt.core.Icepak(project="new_proj_Ipk")
app.modeler.import_3d_cad(file_path)

True

Import and apply configuration file

Import and apply the configuration file. You can apply all or part of the JSON file that you import using options in the configurations object.

out = app.configurations.import_config(conf_file)
app.configurations.results.global_import_success

True

Close project

Close the project.

app.release_desktop()

True
