I have a pressure-outlet BC called "outlet-postchill" that I would like to change to a wall from within a journal file after some amount of flow time. I created a couple variables for the name of the BC using:

(make-new-rpvar 'outlet_wtr "postchill" 'string)
(make-new-rpvar 'outlet/water (string-append "outlet-" (%rpgetvar 'outlet_wtr)) 'string)

Both of these together make the string "outlet-postchill"

When I try the TUI command "/define/boundary-conditions/modify-zones zone-type (%rpgetvar 'outlet/water) wall" I get the following errors:

Error: get-thread: invalid thread id (integer) or name (symbol)
Error Object: 'outlet/water
invalid command [wall]

I would like to do this using Scheme, but I don't know the syntax. I tried "(define boundary-conditions modify-zones zone-type (%rpgetvar 'outlet/water) wall)" but that didn't work either.

Can someone please help with the syntax for this? I have many of these operations to do at certain flow times?

(ti-menu-load-string (format #f "define boundary-conditions modify-zones zone-type ~a wall" (%rpgetvar 'outlet/water)))

Thanks. Looks like I need to learn the Scheme language and how it works with Fluent.

Hi, did you find how to change the boundary conditions from outlet to wall?


I have to do this for some different bpundaries. Change the boundary conditions of each one in different types and the go back to the other.




change outlet-wall-outlet-wall-outlet--- etc

you can control boundary conditions type using TUI commands

also, you can put TUI commands in journal file and execute it
