Hello everyone,
I want to run Fluent unsteady airfoil cases using compute Canada clusters. I am using the batch files and journal files attached. However, my cases are not running successfully.

Please help me accordingly.


Journal File
; SAMPLE FLUENT JOURNAL FILE - UNSTEADY SIMULATION
; ----------------------------------------------
; lines beginning with a semicolon are comments

; Write case and data files in legacy format:
/file/cff-files no

; Read input files (FFF-in.cas and FFF-in.dat):
/file/read-case-data S45.cas

; Write a data (and maybe case) file every 100 time steps:
/file/auto-save/data-frequency 100
/file/auto-save/case-frequency if-case-is-modified

; Write to output sub-directory (appends flowtime and timestep)
/file/auto-save/root-name output/S45-out

; ##### Settings for Transient simulation : #####

; Set the magnitude of the (physical) time step (delta-t)
/solve/set/time-step 0.0001

; Set the max number of iterations per time step:
/solve/set/max-iterations-per-time-step 20

; Set the number of iterations for which convergence monitors are reported:
/solve/set/reporting-interval 1

; ##### End of settings for Transient simulation #####

; Initialize using the hybrid initialization method:
/solve/initialize/hyb-initialization

; Perform unsteady iterations for a specified number of time steps:
/solve/dual-time-iterate 2450,

; Overwrite output files by default:
/file/confirm-overwrite no

; Write final output file (FFF-out.dat):
/file/write-data S45-out

; Write simulation report to file (optional):
/report/summary y "My_Simulation_Report.txt"

; Exit fluent:
"unsteady_simul.jou" 24L, 603C 1,1 Top

Thank you.

check log file generated in your working folder

however, prorpably your problem is here

; Exit fluent:
"unsteady_simul.jou" 24L, 603C 1,1 Top

"unsteady_simul.jou" 24L, 603C 1,1 Top
is not a TUI command

Hi Alex, Thank you for your reply. Yes, the message file shows:

/var/spool/slurmd/job7718886/slurm_script: submit_fluent_bynode.sh: command not found


Can you please how I can submit the file because I need to update it to read the journal file? Thank you.
