Icepak Example

This example shows how you can use PyAEDT to create an Graphic Card setup in Icepak and postprocess results. The example file is an Icepak Project with a model already created and with materials assigned.

Launch AEDT in Graphical Mode

This examples launches AEDT 2021.1 in graphical mode.

import os
import tempfile
import shutil
from pyaedt import examples, generate_unique_name
from pyaedt import Icepak

Open Project

Download Project, opens it and save to TEMP Folder.

project_full_name = examples.download_icepak()

tmpfold = tempfile.gettempdir()

temp_folder = os.path.join(tmpfold, generate_unique_name("Example"))
project_temp_name = os.path.join(temp_folder, "Graphic_Card.aedt")
if not os.path.exists(temp_folder):
shutil.copy2(project_full_name, project_temp_name)

ipk = Icepak(project_temp_name, specified_version="2021.1")
ipk.save_project(os.path.join(temp_folder, "Graphics_card.aedt"))

Create Source Blocks

Create Source block on CPU and MEMORIES

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


pyaedt info: Block on ['CPU'] with 25W Power, created correctly.
pyaedt info: Block on ['MEMORY1', 'MEMORY1_1'] with 5W Power, created correctly.

Assign Boundaries

Assign Opening and Grille

region = ipk.modeler.primitives["Region"]
ipk.assign_grille(, free_area_ratio=0.8)


pyaedt info: Face List boundary_faces created

Mesh Operations

Assign Mesh Region to HeatSink and CPU

mesh_region = ipk.mesh.assign_mesh_region(objectlist=["HEAT_SINK", "CPU"])
mesh_region.UserSpecifiedSettings = True
mesh_region.MaxElementSizeX = "3.35mm"
mesh_region.MaxElementSizeY = "1.75mm"
mesh_region.MaxElementSizeZ = "2.65mm"
mesh_region.MaxLevels = "2"




Create Point Monitor and Setup

ipk.assign_point_monitor(point_position=["-35mm", "3.6mm", "-86mm"], monitor_name="TemperatureMonitor1")
ipk.assign_point_monitor(point_position=["80mm", "14.243mm", "-55mm"], monitor_type="Speed")
setup1 = ipk.create_setup()
setup1.props["Flow Regime"] = "Turbulent"
setup1.props["Convergence Criteria - Max Iterations"] = 5
setup1.props["Linear Solver Type - Pressure"] = "flex"
setup1.props["Linear Solver Type - Temperature"] = "flex"
