Export AC RL matrix of Q3D Parametric results using the API: export_matrix_data

[LuWan-dot]

Dear team,

I found that in Q3D PyAEDT, there is an API called export_matrix_data, which can be used to export matrix results such as AC RL.
However, it does not work for the results in Optimetrics (ParametricSetup).

I can use the following code in Jupyter Notebook to export the AC RL matrix at the nominal condition (result in the Analysis-Setup):

import pyaedt
app = pyaedt.Q3d(projectname="project1", designname="Q3DDesign2")
solution_data = app.export_matrix_data("D:\Usershares\xx\test4.m",problem_type="AC RL",setup="Setup1")

The above code can create a .m file containing the AC RL matrix for the nominal condition.

However, when I specify the design variation in this API, it creates the .m file withan empty AC RL matrix.
import pyaedt

app = pyaedt.Q3d(projectname="project1", designname="Q3DDesign2")
solution_data = app.export_matrix_data("D:\Usershares\xx\test4.m",problem_type="AC RL",setup="Setup1",variations="$CreepDistance='0.8mm' $HeightGateCylinder1='1.3mm'")

Do you happen to have an idea about this API export_matrix_data function?
Many thanks for the help in advance.

Best regards,
Lu

Hi @LuWan-dot,

I'm Giulia, thanks for reaching out!
I'd suggest to get your variations in this way rather than type them manually:
variations app.available_variations.get_independent_nominal_values()
and pass it as argument to the export_matrix_data.

Another thing that I'd suggest you is to avoid using the pyaedt alias.
This has been replaced some releases ago by ansys.aedt.core and it will be a breaking change in your workflow once PyAEDT v.1.0 will be released. Please refer to this page for all the breaking changes that will occur: https://aedt.docs.pyansys.com/version/stable/release_1_0.html#release-1-0.

So for example your workflow will become:

import ansys.aedt.core

app = ansys.aedt.core.Q3d(projectname="project1", designname="Q3DDesign2")

hope this helps,

Kind regards,

Giulia

Hi @gmalinve ,

Nice to know you, Giulia! Thanks for taking care of this question.
Getting the nominal values of independent variables from the code you provided is fantastic. Thank you so much!

I am wondering if there is a code that I can get the variables of each design variation. For instance, in my parametric setup, I have 256 design variations.

My goal is to export not only the matrix result of the nominal condition, but also all other design variations.
Do you have any idea how to achieve this task?

Many thanks for your help!
Best regards,
Lu

Can I ask a simple question wrt thread:
import pyaedt # presently works
import ansys.aedt.core #!!!!! ModuleNotFoundError: No module named 'ansys'

Then I tried
pip install ansys.aedt.core # that does not appear to work.

How does one "install" and "obtain" ansys.aedt.core?

@EEnjk You probably have an old PyAEDT version, the alias was modified months ago, so please update your pyaedt version.

pip install pyaedt -U

This was notified here:

[EEnjk]

thank you, I have updated pyaedt as indicated above with: pip install pyaedt -U
That worked. I am new to python and certainly pyansys / pyaedt, direct guidance is very helpful
** I have another question in the discussions regarding pyaedt & the 2D extractor.
"Pyaedt Q3D, 2D Extractor : either get modal impedance values or export them"
It would be wonderful if you could comment on that. thx again.

Please create a new discussion thread for this topic thanks

Hi @LuWan-dot,

You can access your parametric setups in this way:
self.aedtapp.parametrics.setups
this will give you the list of your parametric setups.
You can get the one you are interested in by parsing by name for example.
[setup for setup in self.aedtapp.parametrics.setups if setup.name == my_setup_name]
If we suppose you have only one you can get your design variations as:

my_setup = self.aedtapp.parametrics.setups[0]
self.aedtapp.parametrics.setups[0].props["Sweeps"]["SweepDefinition"]

but I suggest you to use an IDE (like PyCharm) to debug and see what you can access.
For example this is my PyCharm evaluator:

You can see that in SweepDefinition you can access the design variations info.

Hope this helps!

Kind regards,

Giulia
