PyAEDT is a Python library that interacts directly with the API for Ansys Electronics Desktop (AEDT) to make scripting simpler. The architecture for PyAEDT can be reused for all AEDT 3D products (HFSS, Icepak, Maxwell 3D, and Q3D Extractor), 2D tools, and Ansys Mechanical. PyAEDT also provides support for circuit tools like Nexxim and system simulation tools like Twin Builder. Finally, PyAEDT provides scripting capabilities in Ansys layout tools like HFSS 3D Layout and EDB. The PyAEDT class and method structures simplify operation while reusing information as much as possible across the API.

You can install PyAEDT on CPython 3.7 through 3.10 from PyPI with this command:

  pip install pyaedt

Install PyAEDT with all extra packages (matplotlib, numpy, pandas, pyvista):

  pip install pyaedt[full]

You can also install PyAEDT from Conda-Forge with this command:

  conda install -c conda-forge pyaedt

PyAEDT remains compatible with IronPython and can be still used in the AEDT Framework.

PyAEDT is part of the larger PyAnsys effort to facilitate the use of Ansys technologies directly from Python.

PyAEDT is intended to consolidate and extend all existing functionalities around scripting for AEDT to allow reuse of existing code, sharing of best practices, and increased collaboration.

AEDT is a platform that enables true electronics system design. AEDT provides access to the Ansys gold-standard electro-magnetics simulation solutions, such as Ansys HFSS, Ansys Maxwell, Ansys Q3D Extractor, Ansys Siwave, and Ansys Icepak using electrical CAD (ECAD) and Mechanical CAD (MCAD) workflows.

In addition, AEDT includes direct links to the complete Ansys portfolio of thermal, fluid, and mechanical solvers for comprehensive multiphysics analysis. Tight integration among these solutions provides unprecedented ease of use for setup and faster resolution of complex simulations for design and optimization.

PyAEDT includes functionality for interacting with the following AEDT tools and Ansys products:

• HFSS and HFSS 3D Layout
• Icepak
• Maxwell 2D, Maxwell 3D, and RMXprt
• 2D Extractor and Q3D Extractor
• Mechanical
• Nexxim
• EDB
• Twin Builder

Documentation for the latest stable release of PyAEDT is hosted at PyAEDT documentation.

In the upper right corner of the documentation's title bar, there is an option for switching from viewing the documentation for the latest stable release to viewing the documentation for the development version or previously released versions.

You can also view or download PyAEDT cheat sheets, which are one-page references providing syntax rules and commands for using the PyAEDT API and PyEDB API:

• View or download the PyAEDT API cheat sheet.

• View or download the PyAEDT API cheat sheet.

On the PyAEDT Issues page, you can create issues to report bugs and request new features. On the PyAEDT Discussions page or the Discussions page on the Ansys Developer portal, you can post questions, share ideas, and get community feedback.

To run PyAEDT, you must have a local licenced copy of AEDT. PyAEDT supports AEDT versions 2022 R1 or newer.

PyAEDT supports AEDT Student versions 2022 R1 and later. For more information, see the Ansys Electronics Desktop Student - Free Software Download page on the Ansys website.

A quick and easy approach for automating a simple operation in the AEDT UI is to record and reuse a script. However, disadvantages of this approach are:

• Recorded code is dirty and difficult to read and understand.
• Recorded scripts are difficult to reuse and adapt.
• Complex coding is required by many global users of AEDT.

The main advantages of PyAEDT are:

• Automatic initialization of all AEDT objects, such as desktop objects like the editor and boundaries
• Error management
• Log management
• Variable management
• Compatibility with IronPython and CPython
• Simplification of complex API syntax using data objects while maintaining PEP8 compliance.
• Code reusability across different solvers
• Clear documentation on functions and API
• Unit tests of code to increase quality across different AEDT versions

1. Initialize the Desktop class with the version of AEDT to use.
2. Initialize the application to use within AEDT.

PyAEDT works both inside AEDT and as a standalone application. This Python library automatically detects whether it is running in an IronPython or CPython environment and initializes AEDT accordingly. PyAEDT also provides advanced error management. Usage examples follow.

    # Launch AEDT 2022 R2 in non-graphical mode

    from pyaedt import Desktop, Circuit
    with Desktop(specified_version="2022.2",
                 non_graphical=False, new_desktop_session=True,
                 close_on_exit=True, student_version=False):
        circuit = Circuit()
        ...
        # Any error here will be caught by Desktop.
        ...

    # Desktop is automatically released here.

    # Launch the latest installed version of AEDT in graphical mode

    from pyaedt import Circuit
    with Circuit(specified_version="2022.2",
                 non_graphical=False) as circuit:
        ...
        # Any error here will be caught by Desktop.
        ...

    # Desktop is automatically released here.

You can make a remote application call on a CPython server or any Windows client machine.

On a CPython Server:

    # Launch PyAEDT remote server on CPython

    from pyaedt.common_rpc import pyaedt_service_manager
    pyaedt_service_manager()

On any Windows client machine:

    from pyaedt.common_rpc import create_session
    cl1 = create_session("server_name")
    cl1.aedt(port=50000, non_graphical=False)
    hfss = Hfss(machine="server_name", port=50000)
    # your code here

    from pyaedt.HFSS import HFSS
    with HFSS as hfss:
         hfss["dim"] = "1mm"   # design variable
         hfss["$dim"] = "1mm"  # project variable

    # Create a box, assign variables, and assign materials.

    from pyaedt.hfss import Hfss
    with Hfss as hfss:
         hfss.modeler.create_box([0, 0, 0], [10, "dim", 10],
                                 "mybox", "aluminum")
