= Versions and Availability =
A current list of the versions available on the bwUniCluster and bwForclusters can be obtained from the Cluster Information System: [http://cis-hpc.uni-konstanz.de/prod.cis/ CIS Information on ANSYS]


On the command line interface (CLI) of a particular bwHPC cluster a list of all available ANSYS versions can be inquired as followed
<pre>
$ module avail cae/ansys
</pre>
</pre>
The cae/ansys modules are using the KIT license server and are reserved for members of the KIT only.

= Usage =
= Usage =
== Loading the Module ==
If you wish to load a specific version of "ANSYS" you can do so by executing e.g.:
<pre>
$ module load cae/ansys/15.0
</pre>
to load the version 15.0

You can load the default version of ''ANSYS'' with the command:
<pre>
$ module load cae/ansys
</pre>

== Start commands ==
To start an ANSYS APDL session enter
<pre>
$ ansys150
</pre>
To launch an ANSYS FLUENT session enter
<pre>
$ fluent
</pre>
The following command is to run the ANSYS Workbench
<pre>
$ runwb2
</pre>
Online documention is available from the help menu or by using the command
<pre>
$ anshelp150
</pre>
As with all processes that require more than a few minutes to run, non-trivial ANSYS solver jobs must be submitted to the cluster queueing system.
<br>

= Examples =
== ANSYS APDL batch jobs ==
The following script could be submitted to the queueing system to run an ANSYS APDL job in parallel:
{{bwFrameA|
<source lang="bash">
#!/bin/bash
module load cae/ansys/15.0
export MPIRUN_OPTIONS="-prot"
export MPI_USESRUN=1
cd Arbeitsverzeichnis
export MACHINES=`/software/bwhpc/kit/cae/ansys_inc15/scc/machines.pl`
ansys150 -dis -b -j lal -machines $MACHINES < input.f18
</source>
}}

working_dir could start with $HOME or $WORK .

To submit the example script to the queueing system execute the following (32 cores, 1 GB of memory per core, max. time 600 seconds) :
<pre>
msub -l nodes=2:ppn=16,pmem=1000mb,walltime=600 Shell-Script
</pre>

== ANSYS Fluent batch jobs ==
== ANSYS Fluent batch jobs ==
see http://www.scc.kit.edu/produkte/6724.php > "Kurzanleitung" > "#FLUENT-Aufruf_auf_den_Linux-Clustern_des_SCC"
The following script "run_fluent.sh" could be submitted to the queueing system to run an ANSYS Fluent job in parallel using 4 cores on a single node:
{{bwFrameA|
<source lang="bash">
#!/bin/sh
#MSUB -l nodes=1:ppn=4
#MSUB -l walltime=0:10:00
#MSUB -l mem=16000mb

## setup environment
export MPI_USESRUN=1

## generate hosts list
export run_nodes=`srun hostname`
echo $run_nodes | sed "s/ /\n/g" > fluent.hosts
echo "" >> fluent.hosts

## load ansys module
module load cae/ansys

## start fluent job
time fluent 3d -g -pib -cnf=fluent.hosts -i test.inp
</source>
}}
To submit the example script to the queueing system execute the following:
<pre>
$ msub run_fluent.sh
</pre>
<br>


== ANSYS CFX batch jobs ==
== ANSYS CFX batch jobs ==
see http://www.scc.kit.edu/produkte/3852.php > "Kurzanleitung" > "#CFX_auf_den_Linux-Clustern_des_SCC"
With the script "run_cfx.sh" you can submit a CFX job to the queueing system to run in parallel using 8 cores on two node with the start-method 'Platform MPI Parallel':
{{bwFrameA|
<source lang="bash">
#!/bin/sh
#MSUB -l nodes=2:ppn=4
#MSUB -l walltime=0:10:00
#MSUB -l mem=32000mb

## setup environment
export MPI_USESRUN=1

## load ansys module
module load cae/ansys

## start job
cfx5solve -def test.def -part 8 -start-method 'Platform MPI Parallel'
</source>
}}
To submit the example script to the queueing system execute:
<pre>
$ msub run_cfx.sh
</pre>
<br>
