Thermal analysis with 3D components

This example shows how to create a thermal analysis of an electronic package by taking advantage of 3D components with advanced features added by PyAEDT.

Keywords: Icepak, 3D components, mesh regions, monitor objects.

Perform imports and define constants

Perform required imports.

import os
import tempfile
import time

from ansys.aedt.core import Icepak, downloads

Define constants.

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

Create temporary directory and download files

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.

temp_folder = tempfile.TemporaryDirectory(suffix=".ansys")
package_temp_name, qfp_temp_name = downloads.download_icepak_3d_component(
    destination=temp_folder.name
)

Create heatsink

Create an empty project in non-graphical mode.

ipk = Icepak(
    project=os.path.join(temp_folder.name, "Heatsink.aedt"),
    version=AEDT_VERSION,
    non_graphical=NG_MODE,
    close_on_exit=True,
    new_desktop=True,
)
