EMIT: HFSS to EMIT coupling#

This example shows how you can use PyAEDT to open an AEDT project with an HFSS design, create an EMIT design in the project, and link the HFSS design as a coupling link in the EMIT design.

Perform required imports#

Perform required imports.

import os
import tempfile

# Import required modules
from pyaedt.generic.filesystem import Scratch

from pyaedt import Emit
from pyaedt import Desktop
# Set non-graphical mode

Set non-graphical mode. "PYAEDT_NON_GRAPHICAL" is needed to generate documentation only. You can set non_graphical either to True or False. The Boolean parameter new_thread defines whether to create a new instance of AEDT or try to connect to an existing instance of it.

The following code uses AEDT 2022 R2.

non_graphical = os.getenv("PYAEDT_NON_GRAPHICAL", "False").lower() in ("true", "1", "t")
NewThread = True
desktop_version = "2022.2"
scratch_path = tempfile.gettempdir()

Launch AEDT with EMIT#

Launch AEDT with EMIT. The Desktop class initializes AEDT and starts it on the specified version and in the specified graphical mode.

d = Desktop(desktop_version, non_graphical, NewThread)

example_dir = os.path.join(d.install_path, "Examples\\EMIT")
example_project = os.path.join(example_dir, example_aedt)
example_pdf = os.path.join(example_dir, example_pdf_file)

Create and connect EMIT components#

Create three radios and connect an antenna to each one.

if rad1 and ant1:

rad2 = aedtapp.modeler.components.create_component("GPS Receiver")
ant2 = aedtapp.modeler.components.create_component("Antenna")

Run EMIT simulation#

Run the EMIT simulation. This portion of the EMIT API is not yet implemented.

Save project and close AEDT#

After the simulation completes, you can close AEDT or release it using the pyaedt.Desktop.force_close_desktop() method. All methods provide for saving the project before closing.

aedtapp.release_desktop(close_projects=True, close_desktop=True)
