Default Interrupting a Journal File

Hi All,

I am working with the legacy version of FLUENT and have been trying to use journal files for automating my simulations. I had a small question with regards to usage of journal files.

Is there a way to interrupt a journal file while it is running, check a few things (verify contours etc.) and continue running the journal file from where it was interrupted?

I do understand that pressing Ctrl+C would interrupt the process but how do I revive the journal file from the point of interruption?

I would appreciate your response.

somewhat helpful to you could be placing a scheme command (cx-pause), which will wait for you to press any key (as was described in Pausing Fluent in batch ). This, however does not allow you to check contours or anything (GUI is inactive).
As I am now solving the same problem now, I found a command
(if (= (read) 1) (display "...continue simualtion") (ti-menu-load-string "/exit"))
which could be helpful eg. after Grid check (if anything goes wrong, you simply quit Fluent and can then fix the problem). HOWEVER- this works good, if you simply type this to Fluent's command line. If you on the other hand write exactly the same in a journal file, it does not work. I tried a more complicated version of
(rp-var-define 'a 0 'integer #f)
(display "One for continue, other for exit")
(rpsetvar 'a (read))
(if (= (rpgetvar 'a) 1) (display "...continue simulation") (ti-menu-load-string "/exit"))
but again- typing it works, but reading it from journal causes error.
So, I recommend you (cx-pause), but if anyone could make this (if) sequence work, I would also be grateful;-)
