Non-premixed combustion model using pyFluent

[bnkeeton]

I'm trying to use pyFluent to set up a case with species transport and the non-premixed-combustion model. I set up a simple script below to test out the functionality. The non-premixed-combustion model is shown as an option within the print(species.model.option.allowed_values()) statement, but when I check the state at the end of the script with species.print_state(), it shows option : off.

Is there a way to use this model with pyFluent? Perhaps a mixture pdf needs to be loaded ahead of time?

import ansys.fluent.core as pyfluent

# launch Fluent in solution mode
solver_session = pyfluent.launch_fluent(
    precision=pyfluent.Precision.DOUBLE,
    processor_count=2,
    mode=pyfluent.FluentMode.SOLVER,
)

# load the mesh
mesh_file = "mesh1.msh.h5"
solver_session.settings.file.read_mesh(file_name=mesh_file)
solver_session.settings.mesh.check()

# enable heat transfer by enabling the energy model.
solver_session.settings.setup.models.energy.enabled = True

# setup species transport
species = pyfluent.solver.Species(settings_source=solver_session)
print(species.model.option.allowed_values())

# set species model
species.model.option = "non-premixed-combustion"
species.print_state()

# close Fluent session
solver_session.exit()

Thanks,
Ben

Hi I'm just wondering if there is any update on this. The species-transport model seems to work properly but the non-premixed-combustion does not. If it is not yet implemented, that would be helpful to know.
