bineet_aero is on a distinguished road
Hello,

I am trying to submit a fluent run on a cluster using the following bash script

# ---------------------------------------------------------
#
export EOS=titan03
export CALCUL=test
export NPROC=16
export PPN=8
export VERSION=192
export TYP=3ddp
#usage DEPART=aaaa-mm-jjThh:mm:ss
#export DEPART=2018-06-05T15:41:00
#export DUREE=48:00:00
export CASE=FFF.1-2.cas.gz
export DATA=FFF.1-2-00090.dat.gz
export JOURNAL=jrnl.jou
################################################## #########
runFluentAcademic.sh -sw_name $CALCUL -sw_input $CASE -sw_input $JOURNAL -version $VERSION -sw_ppn $PPN -t $NPROC $TYP -g -i $JOURNAL
################################################## #########


where
NPROC = number of cores
PPN = number of nodes.

The error i am getting is

PPN 8
-1")syntax error: invalid arithmetic operator (error token is "
: integer expression expectedemic.sh: line 125: [: 16
--ntasks-per-node=8
AL_JOB_APP,AL_JOB_XFER
" for ntasks-per-node. numeric value "8


Is it a problem in the runFluentAcademic.sh file (containing the licence information) or just a syntax error ?

Please suggest

thanks

bluebase will become famous soon enough
Is this really the full error message?

Can you share the content of runFluentAcademic.sh? This is likely a custom script.

You might start by quoting the variable values properly, to see whether there is some issue with string formating. Such as:
runFluentAcademic.sh -sw_name "$CALCUL" -sw_input "$CASE"

Btw, for what reason do you need to export the variables? Are they used somewhere downstream in runFluentAcademic.sh?
