Returning output from Fluent console

[PyPablo]

📝 Description of the feature

I cannot find a built in way to get a python object from the /define/named-expressions/list-properties output (ideally a dictionary). This helps verify that user expressions are valid. Currently I am passing through scheme_eval.exec to get the output and then parsing it in Python. Is there a more pythonic way of getting this?

This is particularly painful and necessary to build an error-proof code. Expression syntax and context verification is already performed by Fluent kernel, we just need a way to access this info in a Pythonic way. Ideally returned as a pythonic object, but if not at least as a string to parse.

Even we change list_properties command's output to a dictionary, it is still not stongly-typed and for users it is difficult to guess that a key indicating validity will be found in the returned dictionary unless they are familiar with the original TUI. For such computed properties, we should have either a query:

>>> solver.settings.named_expressions["expr1"].is_valid() --> returns bool

or have a read-only parameter is_valid within the state:

>>> solver.settings.setup.named_expressions["expr1"]()
{'definition': 'AreaAve(StaticPressure, '
               '["inlet1"])',
 'description': '',
 'input_parameter': False,
 'is_valid': <bool>,          --> new read-only state
 'name': 'expr1',
 'output_parameter': False,
 'parameterid': '',
 'parametername': 'expr1',
 'unit': 'Pa'}
>>> solver.settings.named_expressions["expr1"].is_valid()  --> returns bool

for a more Pythonic usage.
