ANSYS/Fluent

The CHPC has an installation of Fluent along with a limited license for academic use only. If you are a full time student or researcher at an academic institution then you may request access to use Fluent on the CHPC clusters. Send your request along with motivation and description of the work in an email to 'helpdesk@chpc.ac.za'.

Installation

Fluent version XX.X is installed in '/opt/gridware/Ansys' and you should add the following lines to your '.bashrc' file in your CHPC home directory:

# include Fluent environment variables and commands
. /opt/gridware/Ansys/ ### to be fixed ###

Running a Fluent Job

On the CHPC clusters all simulations are submitted as jobs to the Moab job scheduler which will assign your job to the appropriate queue and machine. Fluent runs on the three Intel Xeon based clusters: Nehalem, Westmere and Dell.

Example job script:

  #/bin/sh
  #MSUB -l nodes=2:ppn=8
  #MSUB -l feature=nehalem|harpertown|dell
  #MSUB -l walltime=3:00:00
  #MSUB -m be
  #MSUB -V
  #MSUB -o /export/home/username/scratch/stdout
  #MSUB -e /export/home/username/scratch/stderr
  #MSUB -d /export/home/username/scratch
  #MSUB -mb
  ##### Running commands
  exe=/opt/gridware/Ansys/...TO BE FILLED IN...
  nproc=`cat $PBS_NODEFILE | wc -l`
  mpirun -np $nproc -machinefile $PBS_NODEFILE $exe
