Encrypted 3D component conversion#

This example shows how to convert an encrypted 3D component from ACIS to Parasolid in different AEDT releases. If you have models previous to Ansys AEDT 2023 R1 with an ACIS kernel, you can convert it to Parasolid.

Keywords: HFSS, Encrypted, 3D component, Modeler kernel.

Perform imports and define constants#

Import the required packages.

[1]:

import os
import tempfile
import time

[2]:

from pyaedt import Desktop, Hfss, settings
from pyedb.misc.downloads import download_file

FutureWarning: Module 'pyaedt' has become an alias to the new package structure. Please update you imports to use the new architecture based on 'ansys.aedt.core'. In addition, some files have been renamed to follow the PEP 8 naming convention. The old structure and file names will be deprecated in future versions, see https://aedt.docs.pyansys.com/version/stable/release_1_0.html

Define constants.

[3]:

AEDT_VERSION = "2024.2"
OLD_AEDT_VERSION = "2024.1"
NUM_CORES = 4
NG_MODE = False  # Open AEDT UI when it is launched.

Create temporary directory#

Create a temporary directory where downloaded data or dumped data can be stored. If you’d like to retrieve the project data for subsequent use, the temporary folder name is given by temp_folder.name.

[4]:

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

Download encrypted example#

Download the encrypted 3D component example.

[5]:

a3dcomp = download_file(
    directory="component_3d",
    filename="SMA_Edge_Connector_23r2_encrypted_password_ansys.a3dcomp",
    destination=temp_folder.name,
)

Enable multiple desktop support#

[6]:

settings.use_multi_desktop = True

Prepare encrypted 3D component in ACIS#

Launch the old AEDT release.
