Hi,

I'm having trouble with getting my journal file to run on a linux machine (HPC). The file runs perfectly on a Windows 10 platform. Both are running Ansys 18.2 and Fluent 18. Simple journal file commands attached. Transient simulation.

It fails at two lines
1) /solve/initialize/hyb-initialization
2) /solve/dual-time-iterate 10 21

The dual-time-iterate command produces this error, but only on a linux version. /solve/dual-time-iterate 10 invalid command [10]

Any ideas on why, or a possible workaround?

Cheers

Problem Solved! Use the batch command -gu, not -g as it seems fluent requires graphics to run hyb-initialization and dual-time-iterate

Hi,

I am facing the same errors, could you please explain how you solved this issue. How to use -gu command ?

Thanks

Hi Esra,


Here's a (stripped) example of my batch file with the commands I used. I was running on a cluster. Just put the commands similar to testingfluent.txt in your journal file.



#!/bin/bash
#
#PBS commands go here

set echo on
hostname

# Load the ansys module
module load ansys/18.2

# Move to the directory where the job was submitted from
# Create the config file for socket communication library
cd $PBS_O_WORKDIR

rm -f pnodes
cat $PBS_NODEFILE | sort > pnodes
export ncups=`cat pnodes |wc -l`

version=2ddp

# Run Fluent
fluent $version -t$npus -cnf=$PBS_NODEFILE -gu -i journalfile.jou > output_file

You have to close the residual plotting in .cas file(only printing), because you are opening without gui settings. This contradiction makes problem while using journal.
