🐞 Description of the bug
With the recent patch release the from_install method now throws an error, and behaves differently than the standard launch_fluent() entry-point.
📝 Steps to reproduce
Install any recent (patch) release, such as ansys-fluent-core==0.35.1, or 0.37.0.
import ansys.fluent.core as pyfluent
# Works:
session = pyfluent.launch_fluent(version="25.2")
# Throws an unexpected keyword argument:
session = pyfluent.PureMeshing.from_install(product_version="25.2")
session = pyfluent.Meshing.from_install(product_version="25.2")
session = pyfluent.Solver.from_install(product_version="25.2")Traceback:
Traceback (most recent call last):
File "<string>", line 1, in <module>
File ".\pyfluent-certificates\Lib\site-packages\ansys\fluent\core\session_utilities.py", line 177, in from_install
launcher = StandaloneLauncher(**argvals)
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
