Hi to everyone,
I am having a problem with Fluent 12.1 running a Journal I've written. Firstly, although i am putting the cas file and journal on the desktop when i open Fluent to run the journal file it is giving me an error that it is not finding the cas file. Secondly, I would like it to give me the velocity magnitude contours but it is giving me only the residual plots and in grey scale not color as i write in the command. I 've written the commands i used in the journal file for your consideration....maybe i am doing something wrong so i would appreciate it if someone could help me!


Journal File:

/file/read-case fluent1

/file/auto-save/data-frequency/1000

/file/auto-save/retain-most-recent-files yes

/file/auto-save/max-files/1

/solve/iterate/10000

/display/contours velocity-magnitude

/display/contours/filled-contours yes

/display/contours/global-range yes

/display/color-mode/color

/display/dpi

/display/driver/jpeg

/display/save-picture velocity1

/file/write-case-data fluent1_end

Hi,
I am confused: if it is not opening your case, how can it run??
You have to put your journal and case files in the directory where you start Fluent otherwise Fluent isn't going to find the case.

This happens when you use relative paths, i.e. rcd filename instead of providing the absolute path to the case and data file. It is quickly fixed by using absolute paths, but this is probably not a preferred solution.

When you launch Fluent, you launch it in a certain working directory. The way you launch Fluent determines what this working directory is set to. Note if you launch from the interactive window then the working directory is one of the user inputs that most people ignore. If you launch Fluent from a terminal, then it gets more complicated and depends on how you have configured your system to respond to whatever command it is that you use.

After you launch Fluent check the working directory by entering into the TUI:

pwd

If your case and data file are not here then when you do read-case or read-data, and provide only the name of the case/dat file, of course Fluent will not find it. If you absolutely cannot figure out how to set the working directory during launch, then you can still change directories using:

chdir
