Ansys Fluent - 2022 R2.
When run from Workbench, I was presented with an option to use Pressure-Based Coupled solver along with the "Local Time" for the Pseudo Time method.
However, both the manual and the stand-alone instance of Fluent do not provide this option.
Can anyone speak more to this, please?

They do, the solver is identical bar some options in the File menu. Please can you post screen shots.

Thank you for your reply.
Inspecting the "Method" task page in both stand-alone and Workbench look like so:
I've kept all the settings the same to eliminate any effects from other settings.
I have then surveyed the available options in both Fluent instances, and found the following:
There's also discrepancies between the available solver settings, and their descriptions in the documentation.
For instance, on page 3459 - section 32.14 "Performing Calculations with Pseudo Time Method", Fluent User Guide states:
However, I am allowed to use Pseudo Time Method for P-B Transient even when using a segregated solver:
But not for the D-B solver:
And then, on page 3461, Fluent User Guide states:
I think what I'm trying to ask here is whether Fluent ran from Workbench has more options available than when ran as a stand-alone instance?

You've also got steady & transient set up for the first and second set of images to potentially confuse things.
Fluent from WB should be identical to standalone as it's the same solver.
