Get ID of a (fluid) Zone

  When using Fluent (R2019.1) with TUI, how do I get the ID of a (fluid) zone?
  
  For example:
  
  I get the following (simplified) list of zones.
```
/define/boundary-conditions> list-zones
  id  name                       type                material              kind
----





----
 325  fluid-top25              fluid               air                   cell
 324  interior-fluid-top25     interior                                  face
 228  fluid-top                  wall                air                   face
```
  Following How to get the ID of a zone or a surface in Fluent from its name ?
  
  I can extract the ID name according to
```
> (display (zone-name->id 'fluid-top)) 
228
```
  Which obviously gives me the ID of the wall type zone.
  
  How do I get the ID of the fluid type zone without knowing the ID appearing in the name?

  You basically showing the way to get that or I am missing something

  No, because I actually want the id of
```
fluid-top25 
```
  which is 325.
  
  However to use the quoted method I need to know 325 beforehand...

  So you need the ID of the cell zone and not boundary zone,? May I ask for which purpose?

  But it does depends on how the cell zone name has been provided. You will probably need to loop over the type of the zone to just get the ID if you do not the corresponding name.

  Sure, the cell zone is a rotating volume for which I want to set the proper conditions, therefore the id
  
  (though I just figured out that I can also use a wildcards when specifying, e.g. fluid-top )
  
  This cell zone is enclosed by a stationary wall at a certain radius.
  
  Ok, so there is no 'built-in' way, I need to construct scheme routine to do the loop + filter over list-zones?
  
  Besides, where can I find documentation on the built-in scheme functions such as (display (zone-name->id 'fluid-top))?
  
  Thanks.

  If you label it sensibly just select from the GUI. Or are you trying to journal the whole set up?

  I try to model the whole setup.

  Thanks for your replies.
  
  The easiest solutions, (for me) is for now to use wildcards to get the correct zone-name, e.g.
```
/define/boundary-conditions/fluid fluid-top* () <...>
```
  Maybe this will help others having a similar issue.
  
  One last thing, are the fluent scheme functions and the fluent scheme environment documented somewhere?
  
  Thanks.

  There is a couple of non official Fluent Scheme documentation on the net like the one form Javurek. We have internally some material which we share with commercial customer if there is a need for that. Here again not all functions are covered.

  I already found the one from Javurek, though it does not mention what or how many parameters a function need. I am new to Scheme so I am not aware of a way to display a function help (or docstring if there exits something like this).
  
  I have access to the customer portal, where would I find the internal list you mentioned?
