🐞 Description of the bug

when there are more than one case files in the directory where flprj exists, user gets following error while reading a parametric project using casereader

@tejalprabhu01 As you might know, in the present design, each Case object is associated with a single underlying case file, so I think we should introduce a Project class which would provide access to the underlying Case objects.

[tejalprabhu01]

@tejalprabhu01 @prmukherj proposal:

class Project:
   def __init__(self, project_filepath: str) -> None
   def cases(self) -> list (or dict)
   def case(self, id: Union[int, str]) -> Case

>>> prj = Project(prj_path)
>>> prj.cases()
[[0, "elbow.cas.h5"], [1, "mixer.cas.h5"]]
>>> cas = prj.cas(0)
>>> cas.num_dimensions()
3

@seanpearsonuk may be I am not a 100% clear on the concept, but can a Fluent project be associated with multiple cases?

@tejalprabhu01 no, in fact it should not be. I'm trying this out to see what behaviour at all can be relied upon.

@prmukherj we need to get the case file path by reading the xml file (flprj)
