Default Output Residuals in batch mode

Dear Fluent users,

I am running a PEM fuel cell simulation in a batch mode and want to monitor the residuals. I then use the command in the journal file;

it 50
plot/residuals-set/plot-to-file res.txt

it 1

the first 50 its is to solve the problem, the last 1 it is to toggle the data to be written in the txt file... i figure this out some time ago... I do not know if this is an effective way or not, could anyone give me a clever way?

However, the problem is, with or without the last iteration, the file is an empty txt file. I even tested it by running fluent on a stand alone machine (not on HPC) and it did output the residuals data. The command is exactly the same.

I then used any plot command, like plot the oxygen mass fraction contour and output it into a txt file on batch mode, and it worked. This means, the problem is with the residuals plot command. Can you suggest?

Another question is related to licensing. I have 1 PEMFC add-on module license and the guys at HPC said we have 1 HPC pack license, and he mentioned about 8 licenses. Could you please correct me;

I understand that from a standard FLUENT ACADEMIC RESEARCH license, I can run a 4-core job. Plus 1 HPC pack which can cover 8 cores, so in total I can run a 12-core job at maximum, is this right? And what about my PEMFC add-on module license? Is 1 PEMFC license enough?

Thank you very much for any feedback, or conversations...




Regards,

Pattarapong
