ANSYS is a suite of programs which provide
solutions to physical problems posed in almost any area of
engineering. ANSYS includes programs specialized for fluids, structures,
electronics, semiconductors, systems, and multiphysics.

The ANSYS suite includes the FLUENT program, for computational
fluid dynamics simulations. Some separate documentation for FLUENT
is available under "References:".

ANSYS is licensed software, and users wishing to access it must apply
for authorization. The basic process involves having the user's
department head contact Mark Roope ( of the Virginia Tech
Information Technology Procurement and Licensing group. In this way,
an ANSYS license pack can be purchased, and the department head given
a group in the openldap directory. Departmental users can
than be granted access to ANSYS by the department head, using the
group manager tool located at

On any ARC cluster, check the installation details
by typing "module spider ansys".

ANSYS requires that the appropriate modules be loaded before it can be run.
One version of the appropriate commands for use on NewRiver is:

module purge
module load ansys/17.0


The following batch file runs ANSYS with the input file truss.txt.

#! /bin/bash
#PBS -l walltime=0:05:00
#PBS -l nodes=1:ppn=1
#PBS -W group_list=newriver
#PBS -q open_q
#PBS -j oe
module purge
module load ansys/17.0

ansys170 < truss.txt
