Import Materials#

This example shows how to import materials.

Perform imports and define constants#

Perform required imports.

[1]:

import json
from pathlib import Path
import tempfile

from IPython.display import display
from ansys.aedt.core.examples.downloads import download_file
import pandas as pd
from pyedb import Edb

Define constants

[2]:

AEDT_VERSION = "2025.1"

Preparation#

[3]:

temp_folder = tempfile.TemporaryDirectory(suffix=".ansys")
file_edb = Path(temp_folder.name) / "test.aedb"
edbapp = Edb(file_edb, edbversion=AEDT_VERSION)

PyAEDT INFO: Logger is initialized in EDB.
PyAEDT INFO: legacy v0.50.0
PyAEDT INFO: Python version 3.10.11 (tags/v3.10.11:7d4cc5a, Apr  5 2023, 00:38:17) [MSC v.1929 64 bit (AMD64)]
PyAEDT INFO: EDB C:\Users\ansys\AppData\Local\Temp\tmpjefnatp_.ansys\test.aedb created correctly.

Import configuration into example layout#

[5]:

edbapp.configuration.load(config_file=file_json)
edbapp.configuration.run()

True

Save and close Edb#

The temporary folder will be deleted once the execution of this script is finished. Replace edbapp.save() with edbapp.save_as(“C:/example.aedb”) to keep the example project.

[6]:

edbapp.save()
edbapp.close()
