Hi all,

I'm making a journal file which simply perform some iterations and save some files. I'm monitoring two variables, mass flow through an outlet surface and maximum mach number in the domain. Could anyone tell me the command line to save these two output files (.out) into an specific folder? Fluent does not ask me the directory folder, only if I want to save a monitor or not. Where does it save it, and how to change this?

In Linux, the command to save data files is just
wd /home/folder_name

Something similar to monitors?

Also, is it possible to save residuals?

Appreciate the time!
Cheers

I can't find any way to change monitor settings after its creation.
So, the solution is to specify all settings at monitor creation. If you wanna change file/folder during calculation - you need to delete and create monitor once again.
To create monitor:

/solve/monitor/surface/set-monitor

then follow questions in GUI and write your answers to your jou using "enter" or "whitespace" as delimeter.
When you are asked about "write file", answer "yes". Then your enter path to file. You could use 1) absolute path, e.g.

/home/john/work/1.mon

2) relative path (to the folder where FLUENT is currently - after reading case it is where case file is situated):

1.mon

When your run FLUENT in terminal, you need to add at the end of startup line

1& > out.txt

then all information that usually is written in GUI window will be written to file. If you use queue on supercomputer/cluster - this is usually automatically done by queue (you receive log after calculation)
You could ever save your residuals to file! - start FLUENT with

-gu -driver null

in your command line. Then

/plot/residuals
/disp save-pic residuals.png

Voila!))
More info on topic. And in Mr. Bakker's beautiful notes.

Hi Villager - Im trying to do something similar. I created the report definitions and the file name using the GUI. I normally create a case file and import that to a supercomputer/cluster and run batch simulations. Then I use a batch script and this script for the commands (below) and convert it to the Linux language using "dos2unix".

file/read-case-data 03m_21000_result.cas.h5
solve/iterate 1
solve/set/time-step 0.01
solve/dual-time-iterate 9000 30
solve/execute-commands/enable command-1
solve/execute-commands/enable command-2
file/confirm-overwrite yes
exit
yes

I typed the command-1 and command-2 on my Fluent case using the execute commands window. They look like this:

file/write-data filename.dat
file/write-case filename.cas

The execute commands window allow me to specify the frequency to write the files every # time steps, # flow time, or # iterations.

Im trying to do something similar to save the report files and export files (cdat-for-cfd-post&-ensight). How can I create a command to save the report file (monitors files as .out or .txt) and the export files (.cdat) in the supercomputer/cluster? Should I write the command in the execute command window or should I write it in my run script? How do I specify that I want to save the file in the folder of the supercomputer/cluster?

I saw these commands but I dont know how to go from there.

file/transient-export/cdat-for-cfd-post-&-ensight
file/export/cdat-for-cfd-post-&-ensight

report/surface-integrals/area-weighted-average

As I mentioned, I already created the report definitions and the files using the GUI. I just need the commands to save the files using the execute commands window or my run script.

Thank you,
