🐞 Description of the bug

I first imported the .cas and .dat files, and then I wanted to get the relevant data, but I got an error message, here is my source code and error message
Source code

import ansys.fluent.core as pyfluent
from ansys.fluent.visualization import set_config

solver_session = pyfluent.launch_fluent(
    mode="solver"
)
set_config(blocking=True, set_view_on_display="isometric")
import_case = "R1.cas"
import_data = "R1.dat"
solver_session.tui.file.read_case(import_case)
solver_session.tui.file.read_data(import_data)

solution_variable_info = solver_session.solution_variable_info
solution_variable_data = solver_session.solution_variable_data

#etc.

Error message

📝 Steps to reproduce

Directly running it may yield the same result. The two files used in my code cannot be uploaded due to occupying too much space, but I can ensure that the model and data files are read correctly

@tryzang, now the implementation has changed to: solver_session.fields.solution_variable_info and solver_session.fields.solution_variable_data, respectively. The documentation has also been updated recently, which will be part of the next stable PyFluent release.

Thank you.

Hello, @prmukherj
I just tried solver_session.fields.solution_variable_info and solver_session.fields.solution_variable_data, and still shows an error with no associated attributes, AttributeError: 'SettingsRoot' object has no attribute 'fields' . Is there currently no way to use solution_variable_info and solution_variable_data related methods but to wait for the release of the next stable version of pyfluent?
Also, what can I do to make sure that the implementation in pyfluent I'm using is consistent with the documentation I'm reading?
Thank you for your reply and good luck!

Hi @tryzang,
Since you are using "ansys-fluent-core==0.19.2", you need to access using "solver_session.svar_info" and "solver_session.svar_data", respectively. In the current release these will throw deprecated warnings and you can access using the way mentioned in the comments.
For doc you can follow the doc released with the particular PyPi release.
