= Description =
'''ANSYS''' is a general purpose software to simulate interactions of all disciplines of physics, structural, fluid dynamics, heat transfer, electromagnetic etc. For more information about ANSYS products please visit [http://www.ansys.com/Industries/Academic/ http://www.ansys.com/Industries/Academic/]
 
 

= Versions and Availability =

= Usage =
== ANSYS Fluent batch jobs ==
The execution of FLUENT can also be carried out using a shell script. Below is an example of a shell script named <code>run_fluent.sh</code> that starts a FLUENT calculation in parallel on two nodes with 40 processors each on the bwUniCluster:

1. Using IntelMPI:

<pre>
#!/bin/bash
#SBATCH --nodes=2
#SBATCH --ntasks-per-node=48
#SBATCH --time=2:00:00
#SBATCH --mem=90gb
#SBATCH --partition=cpu

module load cae/ansys/2025R2

source fluentinit

scontrol show hostname ${SLURM_JOB_NODELIST} > fluent.hosts
time fluent 3d -mpi=intel -pib -g -t96 -cnf=fluent.hosts -i test.inp
</pre>

2. Using OpenMPI:

<pre>
#!/bin/bash
#SBATCH --nodes=2
#SBATCH --ntasks-per-node=48
#SBATCH --time=2:00:00
#SBATCH --mem=90gb
#SBATCH --partition=cpu

module load cae/ansys/2025R2

source fluentinit

scontrol show hostname ${SLURM_JOB_NODELIST} > fluent.hosts
time fluent 3d -mpi=openmpi -g -t96 -cnf=fluent.hosts -i test.inp
</pre>

To submit the script to the job management system, run:

<pre>
sbatch run_fluent.sh
</pre>

== ANSYS CFX batch jobs ==
The execution of CFX can also be carried out using a script. Below is an example script <code>run_cfx.sh</code> to start CFX with the start method 'Intel MPI Distributed Parallel':

<pre>
#!/bin/sh
#SBATCH --nodes=2
#SBATCH --ntasks-per-node=48
#SBATCH --partition=cpu
#SBATCH --time=0:30:00
#SBATCH --mem=90gb

module load cae/ansys/2025R2

source cfxinit

cfx5solve -def test.def -par-dist $hostlist -start-method 'Intel MPI Distributed Parallel'
</pre>

To submit the script to the job management system, run:

<pre>
sbatch run_cfx.sh
</pre>

== ANSYS Rocky batch jobs ==

The execution of Rocky DEM can also be carried out using a script. Below is an example script <code>run_rocky.sh</code> to run a Rocky DEM simulation on a GPU node:

<pre>
#!/bin/bash
#SBATCH --output=rocky_job_%j.out
#SBATCH --job-name=rocky_job
#SBATCH --partition=gpu_a100_short # GPU patition
#SBATCH --nodes=1
#SBATCH --gpus-per-node=1
#SBATCH --mem=30000 # Total memory (MB)
#SBATCH --time=00:30:00 # Time limit (hh:mm:ss)

module load cae/ansys/2025R2

# Run Rocky DEM
Rocky --simulate "/path/to/Test.rocky"
</pre>

To submit the script to the job management system, run:

<pre>
sbatch run_rocky.sh
</pre>
