Fluent journal file
Dear all, I am trying to get Fluent run as a batch process on a SGI machine. However, my journal file is not working. Can anyone help me figure out the problem with my journal file and batch script? Also can someone post or send a sample journal file? I copied the batch script and journal file below?
Thank you all in advance. ahmet ****************BATCH******************* #PBS -N ahmet1 #PBS -S /bin/tcsh #PBS -j oe #PBS -l cput=10:00:00 #PBS -l ncpus=4,mem=1gb cd $TMPDIR cp /scratch/a0u8545/060719/6inch-15-alt/6-15a-60-060717-00-fl.jou . cp /scratch/a0u8545/060719/6inch-15-alt/6-15a-60-060706-00.cas . module load fluent fluent 3d -g < 6-15a-60-060717-00-fl.jou > outputfile cp outputfile /scratch/a0u8545/060719/6inch-15-alt cp 6-15a-60-060717-00 /scratch/a0u8545/060719/6inch-15-alt cp 6-15a-60-060706-00.dat /scratch/a0u8545/060719/6inch-15-alt qstat -f $PBS_JOBID ********************JOU FILE************************* /file/rc 6-15a-60-060706-00.cas /define/boundary-conditions/velocity-inlet ;(5ft-inlet) ;zone id/name [5ft-inlet] <RETURN> ;Velocity Specification Method: Magnitude and Direction [no] <RETURN> ;Velocity Specification Method: Components [no] <RETURN> ;Velocity Specification Method: Magnitude, Normal to Boundary [yes] <RETURN> ;Reference Frame: Absolute [yes] <RETURN> ;Use Profile for Velocity Magnitude?

Re: Fluent journal file
I'm not sure about the bc settings in your journal file - I would write
/define/boundary-conditions/velocity-inlet 5ft-inlet n n y y n 6.80 y y n 10.764263 n 10.764263 |
Re: Fluent journal file
Thanks PAD, that worked just perfect.
However, I couldn't figure out how to enter scalar when exporting the data to an ascii file. I tried something like following but didn't work. I couldn't find it on the manual either. Can anyone help me with this? Thanksss!!! ahmet file/export/ascii 6-15a-060731 '(point-8 point-9 point-10) n n ????pressure pressure-coefficient velocity-magnitude???? n |
Re: Fluent journal file
Hi guys, I am running the following string in batch mode on a unix system. The script seems to be running fine except "file/export/ascii......" line. I am getting the following error message. Can anyone help me fix the problem? Thanks a lot in advance

Re: Fluent journal file
Dear ahmet u can do all u need to perform batch operation as follow 1-open a new journal file 2-from writting the commands like that file read-case "c:\mesh1.mesh"
and see the response of the program u can learn yourself simply 3-close the journal and select what u need to do than save that in a new journal i hope this useful khairy-Egypt |
Re: Fluent journal file
Thanks Khairy, I will give it a try that way and post my response here. ahmet
