How to specify the list of quantities to export when exporting solution data

[kwheeler9]

Hi all,

I am trying to use the file.export.ascii() function to export solution data at the end of running a simulation with pyfluent. Using the help() function, I can see these are the details of the file.export.ascii() function:

class ascii(Command)
| ascii(name: 'Optional[str]' = None, parent=None)
|
| Write an ASCII file.
|

Parameters
file_name : str
Enter the desired file name to export.
surface_name_list : List
List of surfaces to export.
delimiter : str
Select the delimiter separating the fields.
cell_func_domain : List
Select the list of quantities to export.
location : str
Select the node or cell-center to export data values.

But I cannot figure out what format the values in the cell_func_domain parameter should be to get specific quantities exported. I want to export static pressure, x-wall shear stress, x-face area, y-face area, and dx-velocity_dx, which are all options in the GUI. I have tried specifying just the static pressure with many variations, such as ["Static_Pressure"], ["static_pressure"], ["static pressure"], etc., but I always get an error that the value is not allowed:

RuntimeError: Values contain disallowed entries
Error Object: (Static_Pressure)

Does anyone know what values should be in the list to get the quantities I'm looking for?

Please let me know if there's any other info you need.

Thanks,
Kyle

What is the Fluent version?

I'm using Fluent 2024 r2

Following will work:

solver.settings.file.export.ascii(file_name = "elbow.txt", surface_name_list = ["wall", "inlet1"], cell_func_domain = ["dx-velocity-dx", "y-face-area", "x-face-area", "x-wall-shear", "pressure"])

The allowed variable names can be queried as:

>>> solver.settings.file.export.ascii.cell_func_domain.allowed_values()
['pressure', 'pressure-coefficient', 'dynamic-pressure', ...]

That worked! Thanks for the help, I appreciate it!
