Running two journal files in series (or calling another journal from within a journal

nvarma · August 1, 2018, 09:56

Is it possible? I have large number of files I want two run two scripts on. Instead of making one huge script I wrote two, one of which would call the other.

However fluent gives the following error message":

"Error: A journal is currently open for input or output.
You cannot read and write a journal at the same time,
or read two journals simultaneously.
Error Object: #f"

Is there a workaround to tackle this?

Thanks.

You cannot open a journal file inside a journal file using read journal.

I guess there are lots of hack but are you overthinking it? You simply need to merge the two journal files together before you run, which can be done with simple scripts in linux or windows. You still can write and maintain your .jou files separately the way you have been doing, just merge on-demand.

Recursively using windows cmd or also check here basically some form of copy *.jou newjournal.jou if you have lots of journal files. If you have exactly 2 journal files you'd do something like this:

copy "file1.jou"+"file2.jou" file3.jou

Thank you. That's what I ended up doing, but the file is just...200-300 lines now. Hard to debug. But fortunately it works and problem solved for now.
