How does PyMechanical choose the Mechanical license level? (Pro/Premium/Enterprise)

[ufsaa2022]

Hi,

Our license server provides three Mechanical license levels: Pro, Premium, and Enterprise.

When I launch Mechanical via PyMechanical:
from ansys.mechanical.core import launch_mechanical
mechanical = launch_mechanical()

How does PyMechanical decide which Mechanical license level (Pro / Premium / Enterprise) to use?

Thanks :)

@ufsaa2022 Thanks for opening a discussion.

PyMechanical remote session, itself does not choose the license level.

It launches Ansys Mechanical using the same command-line mechanism as a standalone Mechanical start. License checkout is handled entirely by Mechanical, based on your configured license preferences and what is available on the license server (Pro, Premium, or Enterprise), exactly as if you launched Mechanical manually without PyMechanical.

But you can use APIs to change licenses order, start without license(readonly) etc with API call once Mechanical is launched and connected to PyMechanical. These features available with PyMechanical embedding.

Thank you for your answer.

In PyMAPDL, we can set the license using mapdl = launch_mapdl(license_type='mech_1').
I think it's possible to set it up in the same way in PyMechanical as well. Both Embedding Instance and Remote Session.
This is because, when we have a PPE license, we should avoid unnecessarily using higher-tier licenses.
Is there a way?

Thanks

I will look into this option. Can you create an issue please so we can track it ?
