Run Ansys Journal Files in an opened Workbench from an external Python Script

LStar · December 1, 2022, 05:38

I am trying to run multiple Journal (.wbjn) Files in an opened, already prepared workbench project from an external Python script.

In my Python script i can open the workbench project with the following commands:

ANSYS_exe_path = r'[Ansys Path]/runwb2.exe'
Project_path = ' -I -F [Project Path]/Project.wbpj'
subprocess.Popen("%s %s" % (ANSYS_exe_path, Project_path))

I tried to open the Journal with the following commands:

Journal1_path = '-I -R [Journal Path]/Journal1.wbjn'
subprocess.Popen("%s %s" % (ANSYS_exe_path, Journal1_path))

but with this command it will open a new empty workbench and tries to run the journal there, which results in a error because the journal is specific to the prepared workbench file.

I can also add the commands to open the specific workbench to the journal file. Then it opens the workbench and runs the journal.
This works but because i want to run multiple Journals and can not open the workbench everytime i can not use this way.

So my question is how to open a journal file from python in a specific already opened workbench?

Hi Lstar, did you have any luck regarding this? I am stuck at the same stage.

unfortunally not exactly, i have found one way that works for my problem though.

The way i did it was with the following python commands:

ANSYS_exe_path = r'<ANSYS PATH>/runwb2.exe'

Update_path = '-X -R ' + <PATH TO THE JOURNAL>/runUpdate.wbjn'

p = subprocess.Popen("%s %s" % (ANSYS_exe_path, Update_path))
p.wait() #waiting for the process to conclude

This subprocess will run the workbench journal "runUpdate.wbjn".

The Journal "runUpdate.wbjn" will do two things:

1. Open the desired Workbench Project that i want to change, with the following command:

Open(FilePath="<FilePath>/Design.wbpj")
...

2. Run a Journal that is specified for this Workbench Project with the following command:

RunScript(FilePath="<FilePath>/FullUpdate.wbjn")

When the Journals are finished the Ansys Workbench will close itself again so make sure that you include a save command at the end.
