@tejalprabhu01 is this the same issue that @mkundu1 recently addressed in ansys/pyfluent-parametric#103? I don't know if you have the changes from that PR. Are the extra input paramaters in parametric just the non-parameter expressions that are now filtered out? Or do we still have an issue?

[tejalprabhu01]

@seanpearsonuk as I understand ansys/pyfluent-parametric#103 fixed the filtering of the non-parameter expressions. But as you can see in the screenshot above, there are a lot of parameters that are non-expression type and are still not listed by CaseReader. So I think this is some other issue.

@tejalprabhu01 CaseReader behaviour is correct. This is the expression data in the case. I have indented those which are labeled as (input) parameters>

@seanpearsonuk Thanks for the clarification. The confusion arises because from optiSLang point of view any parameter that has a value and not expression is treated as input parameter. In the list above we can see for example "xc_cold" etc also looks like name-value pair and therefore we expected them to be a part of input parameter list and not as an expression data.
But if that is not the case for Fluent then it is okay. we can close this ticket.

As per Fluent, vel_cold is an input parameter, but xc_cold is not. So both CaseReader and InputParameters are returning the correct set as per Fluent.
