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 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 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 ------------------------ /opt/bwhpc/common/modulefiles ------------------------- cae/ansys/15.0_bw
There are two licenses. The module
cae/ansys/15.0_bw
uses the BW license server (25 academic research, 69 parallel processes) and
cae/ansys/15.0
uses the KIT license server (only members of the KIT can use it).
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_bw
to load the version 15.0 with the BW license.
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/kit/cae/ansys_inc150/scc/machines.pl`
ansys150 -dis -b -j lal -machines $MACHINES < input.f18
|
working_dir could start with $HOME or $WORK .
To submit the example script to the queueing system execute the following (32 cores, 1 GB of memory per core, max. time 600 seconds) :
msub -l nodes=2:ppn=16,pmem=1000mb,walltime=600 Shell-Script
ANSYS Fluent batch jobs
The following script "run_fluent.sh" could be submitted to the queueing system to run an ANSYS Fluent job in parallel using 4 cores on a single node:
#!/bin/sh
#MSUB -l nodes=1:ppn=4
#MSUB -l walltime=0:10:00
#MSUB -l mem=16000mb
## setup environment
export MPI_USESRUN=1
## generate hosts list
export run_nodes=$(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 -pib -cnf=fluent.hosts -i test.inp
|
To submit the example script to the queueing system execute the following:
$ msub run_fluent.sh
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
