Hi CFDers,

I write a pbs script in order to run fluent in my computer server. My PBS:

## fluent environment##
export PATH=/usr/local/ansys_inc/v191/fluent/bin:$PATH

fluent 3d -g -t$NCPUS -cnf=pnodes -i XXX.jou > output.log 2>&1

where,
NCPUS='cat ${PBS_NODEFILE} | wc -l'
pnodes : cat $PBS_NODEFILE | sort > pnodes

when I qsub the script, the output.log wirte: flunet: command not found.

However, when paste the command in terminal, it runs OK.


Best Regards

The script as such does not seem to have any issue. To debug, you can try echoing the PATH variable. Secondly, you can use full path for the command instead of setting path.

Thanks Vinerm, that's helpful. I found a mistake using echo variables. Also, Full path instead of Path variables is adopted. But still it shows the message, fluent: command not found.

here is my scripts:
#!/bin/bash
#PBS -N Fluent-Ma2
#PBS -q intel
#PBS -l nodes=3pn=24
#PBS -S /bin/bash
#PBS -o pbs.log
#PBS -e pbs.err
NCPUS=`cat ${PBS_NODEFILE} | wc -l`

cd $PBS_O_WORKDIR

export PATH=/usr/local/ansys_inc/v191/fluent/bin:$PATH
fluent 3d -g -t${NCPUS} -cnf=${PBS_NODEFILE} -i xxx.jou > output.log 2>&1

Any comments will be appreciate!

Do you load any modules for running simulation when you directly type the command in your terminal? If yes, then you also have to load the module in the PBS script. If not, then you should try with something else, such as, a simple bash script that prints Hello. If that also does not work, then there is problem with PBS.

Yes, Vinerm. You are right. Finally, I found it is the problem of something else.
I noticed that when I ssh to the computaitonal nodes, I can't start fluent normally, which means the computational nodes' configuration has some errors. So I install the ansys software in the directory where the management node and the computational nodes can share each other. Then, it works.
