Enabling Control Program in a Maxwell 2D Project

This example shows how you can use PyAEDT to enable control program in a Maxwell 2D project. It shows how to create the geometry, load material properties from an Excel file and set up the mesh settings. Moreover, it focuses on post-processing operations, in particular how to plot field line traces, relevant for an electrostatic analysis.

Perform required imports

from pyaedt import downloads
from pyaedt import generate_unique_folder_name
from pyaedt import Maxwell2d

Set AEDT version

Set AEDT version.

aedt_version = "2024.1"

Set non-graphical mode

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

non_graphical = False

Download .aedt file example

Set local temporary folder to export the .aedt file to.

temp_folder = generate_unique_folder_name()
aedt_file = downloads.download_file("maxwell_ctrl_prg", "ControlProgramDemo.aedt", temp_folder)
ctrl_prg_file = downloads.download_file("maxwell_ctrl_prg", "timestep_only.py", temp_folder)

Set active design

Set active design.

m2d.set_active_design("1 time step control")

True

Get design setup

Get design setup to enable the control program to.
