ANSYS FLUENT

Introduction

ANSYS FLUENT software contains the broad physical modeling capabilities needed to model flow, turbulence, heat transfer, and reactions for industrial applications ranging from air flow over an aircraft wing to combustion in a furnace, from bubble columns to oil platforms, from blood flow to semiconductor manufacturing, and from clean room design to wastewater treatment plants.

Module Information:

module spider FLUENT

     Versions:
        fluent/2021R2

If you need to use a version of FLUENT earlier that R2021R2 then you will have to use the “legacy” software partition. Infomation on legacy applications can be found here.

Example Submission Script

The example submission script below is suitable for running on the ARC cluster. This example is customised to ensure FLUENT uses the ARC supplied OpenMPI libraries instead of those supplied by ANSYS:

#SBATCH --ntasks-per-node=48
#SBATCH --time=00:10:00
