hi,
I have got a problem with using the high computing facility of our institute, my case consists of a udf, so I loaded the case and data into the fluent of cluster and compiled the udf over there and exported the case and data, which I have submitted through the job script, now the job got submitted but it didn't run any iterations and outputted the case and data. can someone help me with this, I am attaching my job script and journal scripts for reference.



journal :


/file/rcd me18b054case1f.cas.h5
/solve/set/time-step 0.002
/solve/dual-time-iterate 100000 50
/file/wcd steady_result.cas
/exit/yes

job script:

#!/bin/bash
#PBS -o logfile.log
#PBS -e errorfile.err
#PBS -l walltime=47:00:00
#PBS -l select=1:ncpus=40
tpdir=`echo $PBS_JOBID | cut -f 1 -d .`
tempdir=$HOME/scratch/job$tpdir
mkdir -p $tempdir
cd $tempdir
cp -R $PBS_O_WORKDIR/* .
fluent 2d -g -mpi=intel -t40 -cnf=$PBS_NODEFILE -i dynjou1.jou > fluent.out
mv ../job$tpdir $PBS_O_WORKDIR/.

I am attaching the console output

in log file

Warning: property-info: unknown property: characteristic-vibrational-temperature

most likely you have a problem with your case or journal file

[vivek123]

hi, Thanks for the reply, I don't know why that warning is coming, it came even when i loaded the case in a normal pc so probably there is no problem with journal file, and my case is laminar flow past an oscillating cylinder without any thermal part i don't understand why that warning has come

[AlexanderZ]

seems like you have only these 3 lines in journal

> /solve/set/time-step 0.002

> /solve/dual-time-iterate 100000 50

> /file/wcd  steady_result.cas

you didn't initialize solution, that is a must step before calculation
add it above these lines

[vivek123]

I have already initialized the solution before sending the case to the cluster and it reads both case and data, However I guess there is a problem with the version in which I made the case and version of the cluster which is why I guess the warning came, when I made the case again using an older version of ANSYS the case got submitted fine and its running now, but it is extremely slow even compared to my pc, I don't know why that's happening.

[AlexanderZ]

solution must be initialized right before computation.
you can't initialize and save case file then run it later without reinitialization
