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/
Versions and Availability
A list of versions currently available on all bwHPC-C5-Clusters can be obtained from the
Cluster Information System CIS
{{#widget:Iframe

}}
On the command line interface of a particular bwHPC cluster a list of all available ANSYS versions can be inquired as followed
$ module avail cae/ansys -------------------------- /opt/bwhpc/kit/modulefiles -------------------------- cae/ansys/15.0 cae/ansys/16.2 cae/ansys/17.2 cae/ansys/18.2
The cae/ansys modules are using the KIT license server and is reserved for members of the KIT only.
Usage
Loading the Module
If you wish to load a specific version of ANSYS you can do so by executing e.g.:
$ module load cae/ansys/15.0
to load the version 15.0.
You can load the default version of ANSYS with the command:
$ module load cae/ansys
Start commands
To start an ANSYS Mechanical session enter
$ ansys150
To launch an ANSYS FLUENT session enter
$ fluent
The following command is to run the ANSYS Workbench
$ runwb2
Online documention is available from the help menu or by using the command
$ anshelp150
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.
Examples
ANSYS Mechanical batch jobs
The following script could be submitted to the queueing system to run an ANSYS Mechanical job in parallel:
#!/bin/bash
module load cae/ansys
export MPIRUN_OPTIONS="-prot"
export MPI_USESRUN=1
cd Arbeitsverzeichnis
export MACHINES=`/software/bwhpc/common/cae/ansys_inc150/scc/machines.pl`
ansys150 -dis -b -j lal -machines $MACHINES < input.f18
|
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) :
msub -l nodes=2:ppn=16,pmem=1000mb,walltime=600 Shell-Script
