Hi,
I am trying to write a journal file to submit a Fluent job at HPC. However, I have received some errors after submission.

I have written two files submission file "ANSYS.sub" and "fluent.in".

The "ANSYS.sub" file is:

#!/bin/bash -l
#PBS -N FLUENT3D
#PBS -l walltime=1:00:00
#PBS -l mem=8GB
#PBS -l ncpus=8
#PBS -j oe
#PBS -l ANSYS=1
#PBS -l ANSYS_HPC=8
module load ansys/19.0
cd ~/SIMULATION/PAPER3/DepthHeight/Nima
fluent 3ddp -g -t 8 -i fluent.in > fluent.out

"Fluent.in" file is also as below:

/file/read-case-data Scen1.cas
/solve/iterate 1000
/file/write-data Scen1.dat
/exit yes

The simulation is stopped and Fluent.out also showed the following error message:

===============Message from the Cortex Process=========
Fatal error in one of the compute processes.
=================================================

The job file also shows the following error:
pkg/suse12/software/ansys/19.0/v190/fluent/fluent19.0.0/bin/fluent: line 2641: 9992 Segmentation fault (core dumped) $NO_RUN $CORTEX_PRE $EXE -f $FLUENT_PROD $CX_FLAGS "$CX_FUNCTION"

It would be much appreciated if anyone could help me regarding this issue.


Cheers,
Nima

you just add the initialisation step to your journal file


/file/read-case-data Scen1.cas
/solve/initialize/initialize-flow
/solve/iterate 1000
/file/write-data Scen1.dat
/exit yes
