A short description of the software

This documentation is valid for

Quick howto with PBS submission script example:

# # # module load ansys/14.5.1 cd ${PBS_O_WORKDIR} fluent 2d -g -t16 -cnf=$PBS_NODEFILE -i flutest
 * 1) !/bin/bash -l
 * 1) PBS script for launching Fluent in batch mode
 * 1) PBS -l walltime=00:10:01
 * 2) PBS -l select=1:ncpus=16:mpiprocs=16
 * 3) PBS -N Fluent
 * 1) run Fluent 2d without GUI using 16 processors

Copy this script to your working directory at /scratch and submit it there by qsub.

The input file "flutest" contains the appropriate Fluent text commands, e.g.

file read-case-data myproblem_01.cas solve iterate 1000 file write-case-data myproblem_01.cas yes solve iterate 1000 file write-case-data myproblem_01.cas yes solve iterate 1000 file write-case-data myproblem_01.cas yes solve iterate 1000 file write-case-data myproblem_01.cas yes exit

The case files here myproblem_01.cas and myproblem_01.dat should have been created through interactive run of Fluent with GUI at your PC or Frontend of Bellatrix.

The input file can be created by any text editor or be the same as the journal file, which can be generated directly using the fluent text user interface command window within the GUI.
