Ansys

Introduction

Ansys offers a comprehensive software suite that spans the entire range of physics, providing access to virtually any field of engineering simulation that a design process requires.

Availability

Ansys is available on ARC systems. Virginia Tech maintains a limited quantity of Ansys network licenses through the university’s IT Procurement and Licensing Solutions. Versions available on ARC clusters:

• ANSYS/2025R1

• ANSYS/2024R1

Interface

The primary interface for using Ansys on ARC resources is via the command line. For example on Tinkercliffs, you can get detailed command line help for using Abaqus like this:

[mypid@tinkercliffs1 ~]$ module load ANSYS/2025R1
[mypid@tinkercliffs2 useful_scripts]$ fluent -help
/apps/common/software/ansys/2025R1/v251/fluent/fluent25.1.0/bin/fluent -r25.1.0 -help
Usage: fluent [version] [-help] [options]
options:
  -act            load ACT Start page,
  -affinity=<x>   set processor affinity; <x>={core | sock | off>,
  -case <file_path> [-data]
                  reads the case file immediately after Fluent
                  launches; can include the data file if it
                  shares the same name as the case file,
  -cflush         flush the file cache buffer,
  -cnf=<x>        specify the hosts file,
  -command="<TUI command>"
                  run TUI command on startup,
  -driver <name>  sets the graphics driver;
                  <name>={opengl2 | x11 | opengl2-mesa | null},
  -env            show environment variables,
  -g              run without GUI or graphics
