1 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/
2 Versions and Availability
A current list of the versions available on the bwUniCluster and bwForclusters can be obtained from the Cluster Information System: 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
$ module avail cae/ansys
3 Usage
3.1 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
3.2 Start commands
To start an ANSYS APDL 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.
4 Examples
4.1 ANSYS APDL batch jobs
The following script could be submitted to the queueing system to run an ANSYS APDL job in parallel:
#!/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
|
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
4.2 ANSYS Fluent batch jobs
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:
#!/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 -t4 -pib -cnf=fluent.hosts -i test.inp
|
To submit the example script to the queueing system execute the following:
$ msub run_fluent.sh
4.3 ANSYS CFX batch jobs
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':
#!/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'
|
To submit the example script to the queueing system execute:
$ msub run_cfx.sh
