How to check and wait for Licences

[lstubbig]

Hello,
we are using a pool of floating licences. When all licences are in use models are opened in read-only mode and the pymechanical automation fails at some point, eg trying to apply boundary conditions. When running larger parameter studies this causes frequent manual restarts and disrupts the automated workflow.
What is the best way to handle this situation? Ideally I would like the launch_mechanical() function to wait for an available licence. Is this something that can be readily implemented manually?
Thanks for suggestions!

Hi @lstubbig ,

Currently launch_mechanical will not wait for license. If there is no license available it wont take any. You can have a check in your workflow with below information.

if launch_mechanical is unable to grab license then printing pymechanical app will not show any thing in representation string,

with license

from ansys.mechanical.core import launch_mechanical
app=launch_mechanical()
print(app)

Ansys Mechanical [Ansys Enterprise]
Product Version:251
Software build date: 11/27/2024 09:34:44

Without license

Ansys Mechanical []
Product Version:251
Software build date: 11/27/2024 09:34:44

you can have a check in above to see if pymechanical app has obtained the license or not.

The other way is , after app is created you can run
app.run_python_script("Ansys.ACT.Mechanical.MechanicalAPI.Instance.ReadOnlyMode") which will give True if no license is checked out. False if there is license.

Let me know if this helps,

Thanks, that already helps! Of course a built-in waiting feature would be nice to have in the future.
