Display CPU-Time Post-Processing

Kaaji1359 · July 31, 2013, 19:16

Hello,

I am trying to run a batch file on LINUX but I need to know the total CPU time and preferably the time per iteration. I know several different TUI commands to display CPU times; however, I don't know how to view this data after closing FLUENT.

1) Is there a way to view total elapsed time, etc., after closing FLUENT?? (Is it saved in the .dat.gz file?)
2) Is there a way to print everything that's displayed in the command window to a file?? That would allow me to use TUI commands in my journal file and view them after.

Thanks.

Are you running Fluent in parallel? If yes, you can start a transcript from a journal file and log the CPU usage at the end (/parallel/timer/usage). Here is an example of a journal:

Code:

file confirm-overwrite? no
file start-transcript "outputfile.txt"
file read-case "case.cas"
solve initialize hyb-initialization
solve dual-time-iterate 5 1000
parallel timer usage
file stop-transcript
exit yes
