Hey all,

I'm trying to write a journal file to run in Batch mode on our HPC. I keep getting the same problem in the output fule which is as follows. Below is the output text

> Invalid cell zone.
Invalid cell zone.

Halting due to end of file on input.

Have you tried manually executing the commands in the journal one a time? Journals are very sensitive; if the conditions change and some function now takes a different number of inputs, the whole thing is likely to fall apart in the way you're seeing.

I have indeed. They seem to be fine locally, but when I send it to the HPC, then no use.....The problem seems to arise more when FLUENT has to overwrite a file for instance. It's beginning to drive me nuts

Having to overwrite a file sounds like a classic example of a case where it might have an extra prompt (asking you if you want to overwrite, which it wouldn't even ask if there wasn't already a file), tripping your journal up. Does it always fail, or just in some cases? If it's only failing in some cases, I'm not sure what you can do with just journals to make it more robust. The simplest thing (rather than seeing what Scheme or UDFs could do) might be to take steps outside of Fluent to avoid the problem scenarios, e.g. have a batch script look for existing output files and move/delete them before launching Fluent.
