Case class and other code here contains docstrings: https://github.com/pyansys/pyfluent/blob/main/src/ansys/fluent/core/filereader/case.py

...but they don't appear in the docs:
https://fluent.docs.pyansys.com/dev/api/general/case_reader.html

which is apparently all based on rst file.

Note that this code itself is subject to change: #1464.
