Hi, I am running my 2D PCM (solidification) simulation on my university server by uploading case file, fluent.sh file and journal (.jou) file. I am running it by standard initialization method by giving initial temp to pcm interface. I also patch the pcm_face for temp. I am confused that I need to write commands for these steps in journal file or not? currently I wrote following cmds.

 

/file/read-case coco1a.cas.gz

/solve/initialize/flow/initialize-temperature 302.15

/solve/initialize/initialize-flow

/solve/set/time-step 1

/solve/dual-time-iterate 8400 50

/file/write-case ./END_ok.cas.gz

/file/write-data ./END_ok.dat.gz

 

it gives following error.

 

ls: cannot access 'gt[0111,0215,0519]': No such file or directory cat: 'gt[0111,0215,0519]': No such file or directory /var/spool/slurmd/job35964/slurm_script:

line 50: fluent: command not found

 

is this error with .jou file or start_fluent.sh file?

 

P.S. My program is running on my laptop without any error.

A better approach might be to write case & data from your local machine. The journal then reads case & data and runs: all set up is then done via the GUI. The error you're seeing looks to be disc or queue related, it's not a typical Fluent problem: the "No such file or directory /var/spool/slurmd/job35964/slurm_script" is the clue.

Hi Rob, thank you for your reply. I have done the same I have write the case file from my local machine. and then used start_fluent.sh and journal file to run on the server. can you tell the about journal file are all these cmds OK for transient simulation run through standard initialization? I can also share the journal and .sh file

Best way to check is run the journal locally, just set the iteration/time step  count to 1-2. That's how I check journals! My only comment is your time step wants checking - very roughly you want 10 time steps for the flow to cross a cell.
