Set up headlamp case

[ansjsia]

Implemented the headlamp radiation case (Monte Carlo radiation model) from the Fluent tutorial in PyAnsys.

@dnwillia @seanpearsonuk Hi, would you be able to advise on fixing a build issue? The documentation build is failing on line 233 of radiation_headlamp.py where it calls meshing.tui.mesh.check_mesh() to check the mesh:

/home/ansys/actions-runner/_work/pyfluent/pyfluent/examples/00-fluent/radiation_headlamp.py failed leaving traceback:

I can't reproduce this on my local machine, which is running version 0.18.dev0 of ansys-fluent-core.

Can you import headlamp_pmdb_file instead of headlamp_spaceclaim_file? I'm getting the following error in a local run with docker:

Error: The *.scdoc file format is not supported on Linux and its equivalent /mnt/pyfluent/headlamp.scdoc.pmdb is not available. As a workaround, you can import the *.scdoc file on a Windows machine (using the 'Save PMDB' option in the Import Options dialog) and then use the generated .pmdb file as the import file on your Linux system.

Fluent expects headlamp.scdoc.pmdb instead of headlamp.pmdb as replacement on Linux which seems to be an incorrect behaviour.

I think Mainak is right. The CI/CD runs on Linux so you need to use the pmdb for the documentation build pipeline. If you look at the other examples with meshing included they use the pmdb.

@mkundu1 @dnwillia-work It works correctly now, thanks!

[ansjsia]

@mkundu1 I'm getting this unit test fail on v23.2.0, but it's only occurring intermittently. It didn't seem to be happening yesterday. Do you have any insight on fixing this?

ERROR tests/test_flobject.py::test_find_children_from_settings_root_232 - RuntimeError: The connection to the Fluent server could not be established within the configurable 60 second time limit.

[raph-luc]

@ansjsia I can answer that, that is a random test failure being tracked here: #1747

You can just re-run the failed tests when that happens

[raph-luc]

Minor suggestion

[raph-luc]

Looks great, thanks @ansjsia

While building the docs for this example, I realized a few things seem to have changed about how all examples are displayed (or at least I didn't remember this behavior), created an issue tracker so we can look into this later: #2044

Hi,
When I try to run locally is crashing in the following line :
radiation = models.radiation

It says It can not find the .radiation model.
I am using 23.1
Any hint how to solve it ?

[ansjsia]

@amscosta You're likely getting that error because you're using 23.1, whereas this example was developed for 23.2-24.1. I'm not sure the radiation model is exposed for the 23.1 API.

[amscosta]

Thanks for the reply.
How can I verify that "exposition" ?
Would be great if each examples tells the version that is currently designed to work.

Thanks for the reply. How can I verify that "exposition" ? Would be great if each examples tells the version that is currently designed to work.

@amscosta we currently maintain the examples to be guaranteed to work with the latest release of Fluent.
