Failure in Analysis using PyAEDT

[ghost]

Hi,

I'm getting errors when analysis in HFSS, so I would like to resolve them.

Using PyAEDT, I'm trying to analyze after changing the value of variable 'L1'.
The code is following:

import sys
import atexit
from pyaedt import *
import pyaedt
pyaedt.settings.use_grpc_api=False

version = '2022.2'
print("Loading the PyAEDT Console.")

hfss = Hfss(projectname="antenna.aedt", designname="Design1", specified_version=version, new_desktop_session=False, non_graphical=False, close_on_exit=False, student_version=False)

hfss["L1"] = "26.5mm"

hfss.analyze_setup("Setup1")

It works fine up to the point where the value of variable 'L1' is changed.
Setup1 is already set up when I designed the antenna model.

It displays the following error message when I carry out the program.

PyAEDT INFO: Key Desktop/ActiveDSOConfigurations/HFSS correctly changed.
PyAEDT INFO: Solving design setup Setup1
PyAEDT INFO: Key Desktop/ActiveDSOConfigurations/HFSS correctly changed.
PyAEDT ERROR: Error in Solving Setup Setup1
False

The result was same when I entered hfss.analyze() instead of hfss.analyze_setup("Setup1"), by the way.

Can anyone tell me what is wrong with this code?

Thank you.

Hi @crapemyrtle-841 ,

It looks like something in the design is incorrect when you change this variable, did you validate the design before analyzing it?

Please share the project in a zip file and the community will be able to help you. If you have problems with the validation, it is not a PyAEDT problem, please contact Ansys customer support in that case.

Hi @Samuelopez-ansys

Thank you for your response.
I attached a zip file.
antenna.aedt.zip

It worked correctly when I analyzed this model in HFSS without PyAEDT.
But, it displays the error when using PyAEDT.
Please tell me why it doesn't work correctly.

Hi @crapemyrtle-841 ,

It is working fine for me:

from pyaedt import *
import pyaedt

pyaedt.settings.use_grpc_api = False

version = '2023.2'
print("Loading the PyAEDT Console.")
project = r"C:\Users\slopez\Downloads\antenna_test.aedt"
hfss = Hfss(projectname=project, designname="Design1", specified_version=version, new_desktop_session=False,
            non_graphical=False, close_on_exit=False, student_version=False)

hfss["L1"] = "26.5mm"

hfss.analyze_setup("Setup1", num_cores=4)

hfss.release_desktop(False, False)

Please update pyaedt, because probably you are using an old version, I am using pyaedt v0.7.3

Hi @Samuelopez-ansys

Thank you for running it.
It worked fine by using num_cores=4.
Thank you so much!
