AEDT connect session example

This example shows how to use the Common AEDT API to connect to an existing AEDT session, create a HFSS design and create a waveguide.

Perform required imports

Perform the required imports.

import sys
from ansys.aedt.toolkits.common.backend.api import AEDTCommon
import ansys.aedt.core

Initialize toolkit

Initialize the toolkit.

toolkit = AEDTCommon()

Get toolkit properties

Get the toolkit properties, which contain the project information.

properties_from_backend = toolkit.get_properties()

# ## Initialize AEDT
#
# Initialize AEDT using PyAEDT and then release it.
ansys.aedt.core.settings.enable_logger = False
app = ansys.aedt.core.Desktop(specified_version=properties_from_backend["aedt_version"],
                     non_graphical=properties_from_backend["non_graphical"])
app.release_desktop(close_projects=False, close_on_exit=False)

True

Get AEDT sessions

Get AEDT sessions and select the first one.

sessions = toolkit.aedt_sessions()
first_key, first_value = next(iter(sessions.items()))
if first_value == -1:
    use_grpc = False
    selected_process = first_key
else:
    use_grpc = True
    selected_process = first_value

DEBUG - Active AEDT sessions: {1968: 49633}.

Set properties

Specify the AEDT session selection.

new_properties = {"selected_process": selected_process, "use_grpc": use_grpc}
flag, msg = toolkit.set_properties(new_properties)

INFO - Updating internal properties.
DEBUG - Updating 'selected_process' with value 49633
DEBUG - Updating 'use_grpc' with value True
DEBUG - Properties were updated successfully.

Initialize AEDT

Launch a new AEDT session in a thread.

thread_msg = toolkit.launch_thread(toolkit.launch_aedt)

DEBUG - Starting thread: Toolkit_Thread
DEBUG - Toolkit is not connected to AEDT.
DEBUG - Launching AEDT.

Wait for the toolkit thread to be idle

Wait for the toolkit thread to be idle and ready to accept a new task.

idle = toolkit.wait_to_be_idle()
if not idle:
    print("AEDT not initialized.")
    sys.exit()

DEBUG - Toolkit is idle and ready to accept a new task.

Connect design

Connect or create a new design.

toolkit.connect_design("HFSS")
