create_touchsthone_component freezes program execution #3002

Closed ryand323 closed 1 year ago

Before submitting the issue

Description of the bug

modeler.components.create_touchstone_component() freezes program execution. I am unable to create a Nport component in an aedt circuit.

Program execution continues until this function call, then idles indefinitely.

Not sure if this is a bug, but help is be appreciated.

Steps To Reproduce

Code: import os from matplotlib import pyplot as plt import numpy as np import pyaedt

cir = pyaedt.Circuit(projectname=pyaedt.generate_unique_project_name(), new_desktop_session=False, non_graphical=False)

tdr1 = cir.modeler.components.components_catalog["Probes:TDR_Single_Ended"].place("tdr1")

print("Making Touchstone Component") nport1 = cir.modeler.components.create_touchsthone_component(model_name="dut.s4p") #dut.s4p is in the directory, I have also tried using the full path

Are there any updates to this issue request?

Samuelopez-ansys commented 1 year ago

Hi @ryand323 ,

Please try to import the NPort manually to verify it is not a problem, of the file.

I have tried with this one:

https://github.com/ansys/pyaedt/blob/main/_unittest/example_models/T21/SSN_ssn.s6p

And it works perfectly: circuit

ryand323 commented 1 year ago

It does appear to be related to the s-parameter files being imported. SSN_ssn.s6p imported correctly with pyaedt into the circuit simulator.

Opening up the touchsone files for comparison, it appears SSN_ssn.s6p is an exported file from aedt:

The s-parameter file I would like to use comes from a VNA measurement. The way data is formatted is quite a bit different, not to mention different units.

Does the pyaedt function only accept files with the AEDT formatting and that is all this issue is?

Samuelopez-ansys commented 1 year ago

@ryand323 Did you try to import this VNA touchstone in Circuit manually?

Because if it does not work, you should contact the Ansys support to help you because it is related to AEDT.

pyAEDT accepts the same that Aedt accepts, if in AEDT works please share the file, because one solution could be formatting the file.

@Samuelopez-ansys The VNA touchstone s-parameters can be loaded into circuit manually. It does not load with pyaedt. The AEDT and Keysight files are delimited very different, perhaps this is a python problem. See the attached s4p file. Keysight_VNA_microstrip.zip
