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

Perform required imports.

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

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)

Launch Maxwell 2D

Launch Maxwell 2D.

m2d = Maxwell2d(projectname=aedt_file,
                specified_version="2023.2",
                new_desktop_session=True,
                non_graphical=non_graphical)

Initializing new desktop!

Set active design

Set active design.

m2d.set_active_design("1 time step control")

Returning found desktop with PID 11480!

True

Get design setup

Get design setup to enable the control program to.

setup = m2d.setups[0]

Enable control program

Enable control program by giving the path to the file.

setup.enable_control_program(control_program_path=ctrl_prg_file)

True

Analyze setup

Analyze setup.

setup.analyze()

Plot results

Plot Solved Results.

sols = m2d.post.get_solution_data("FluxLinkage(Winding1)",variations={"Time":["All"]},  primary_sweep_variable="Time")
sols.plot()
