CFX

CFX is a Computational Fluid Dynamics (CFD) and Engineering package. CFX contains:

• Advanced coupled multigrid linear solver technology
• meshing flexibility
• parallel enabled
• pre- and post-processing capabilities

Examples of uses include:multiple frame of reference, turbulence, combustion and radiation, Eulerian two phase and free surface flow.

In addition, CFX offers an open architecture that encourages customization on all levels. Both input and results are in accessible formats that allow easy customization.

Usage

A sample batch job for running a CFX job is as follows:

#!/bin/bash
#PBS -q normal
#PBS -l walltime=00:10:00
#PBS -l ncpus=96
#PBS -l mem=Gb
#PBS -l wd
#PBS -l software=ansys_<institution>

module load ansys/2021r1
module load ansys_licence/<institution>

export CFX5_OPENMPI_DIR=$OPENMPI_ROOT
cfx5solve -def "StaticMixer.def" -part $PBS_NCPUS -start-method Gadi_openmpi

This script will work for an arbitrary number of cpus, please choose it carefully according to your problem size.

License

The license is for academic usage. Please request membership of the Fluent software group. to get access to this software. Users from the following institutions have access to their own institution licenses and should join the corresponding software group as well as the general Fluent software group.

UNSW

Staff members of the University of NSW who are part of the unsw_ansys software group can access their own license files to run Fluent. To do this you will need a batch script along the lines of

#!/bin/bash
#PBS -q express
#PBS -l walltime=00:10:00
#PBS -l ncpus=16
#PBS -l mem=32GB
#PBS -l software=unsw_ansys
#PBS -l wd
module load cfx/17.2
module load unsw-ansys-license
cfx5solve -def "StaticMixer.def" -part $PBS_NCPUS -start-method Raijin

RMIT

Staff members of RMIT who are part of the ansys_rmit software group can access their own license files to run Fluent. To do this you will need a batch script along the lines of

#!/bin/bash
#PBS -q express
#PBS -l walltime=00:10:00
#PBS -l ncpus=8
#PBS -l mem=2Gb
#PBS -l software=ansys_rmit
#PBS -l wd
module load cfx/17.2
module load ansys_licence/rmit
cfx5solve -def "StaticMixer.def" -part $PBS_NCPUS -start-method Raijin

University of Wollongong

Staff members of UoW who are part of the ansys_wollongong software group can access their own license files to run Fluent. To do this you will need a batch script along the lines of

#!/bin/bash
#PBS -q express
