import ansys.fluent.core as pyfluent from ansys.fluent.core import examples

import_filename = examples.download_file("mixing_elbow.pmdb", "pyfluent/mixing_elbow") meshing = pyfluent.launch_fluent(precision="double", processor_count=10, meshing_mode=True,show_gui=True)

meshing.workflow.InitializeWorkflow(WorkflowType="Watertight Geometry")

when I am trying to run the above commands it is throwing Session object has no attribute worflow

AttributeError Traceback (most recent call last) Input In [2], in <cell line: 1>() ----> 1 meshing.workflow.InitializeWorkflow(WorkflowType="Watertight Geometry")

AttributeError: 'Session' object has no attribute 'workflow'

@pavankumarkonchada, Actually we have a new launcher preference in place now. So, either use any one of the following:

1. Session = pyfluent.launch_fluent(precision="double", processor_count=10, meshing_mode=True, show_gui=True) Session.meshing.workflow.InitializeWorkflow(WorkflowType="Watertight Geometry")

or, 2. meshing = pyfluent.launch_fluent(precision="double", processor_count=10, mode="meshing", show_gui=True) meshing.workflow.InitializeWorkflow(WorkflowType="Watertight Geometry")

Both the above techniques will work. However, second approach is preferred as the first approach has been deprecated. Please let us know if the issue still persist. Thank you

@prmukherj that's correct. In the example from @pavankumarkonchada, it would have been necessary to call meshing.meshing.workflow.InitializeWorkflow(WorkflowType="Watertight Geometry")

[pavankumarkonchada]

Using the second method I am getting this error TypeError Traceback (most recent call last) Input In [4], in <cell line: 3>() 1 import ansys.fluent.core as pyfluent 2 from ansys.fluent.core import examples ----> 3 meshing = pyfluent.launch_fluent(precision="double", processor_count=10, mode="meshing", show_gui=True) 4 meshing.workflow.InitializeWorkflow(WorkflowType="Watertight Geometry")

TypeError: launch_fluent() got an unexpected keyword argument 'mode'

@pavankumarkonchada, do you have the latest version of the code? Could you please confirm that? Thank you

I am following as mentioned in the below blog https://www.ansys.com/en-in/blog/open-source-access-to-fluent-with-pyfluent And after that when I have opened in launcher.py I see the arguments passed to launcher definition is as below def launch_fluent( version: str = None, precision: str = None, processor_count: int = None, journal_filename: str = None, meshing_mode: bool = None, start_timeout: int = 3000, additional_arguments: str = "", env: Dict[str, Any] = None, start_instance: bool = None, ip: str = None, port: int = None, cleanup_on_exit: bool = True, start_transcript: bool = True, show_gui: bool = None, ) -> Session:

The referenced blog doesn't use meshing.
