This wiki page guides you on how to use ISV codes on our systems.

HAWK

Please check beforehand via Application_software_packages, if you are allowed to use the installed ISV packages.

ANSYS

Please check via module environment (Module_environment(Hawk)), which versions are currently available. Typical batch submission script examples are given below.

CFX

On HAWK we currently provide two methods to run CFX in parallel. One can choose between two methods:

  1. -start-method "HMPT MPI Distributed Parallel" is utilising HMPT. For more details please see MPI(Hawk)
  2. -start-method "Open MPIHAWK Distributed Parallel" uses a recent OpenMPI version.

A typicall batch script could look like this:

#!/bin/bash
###asking for 2 nodes for 20 minutes
#PBS -l select=2:mpiprocs=128
#PBS -l walltime=00:20:00
#PBS -N nameOfJob
#PBS -k eod

###load module
module load ansys/19.5

###change to the current working directory
cd $PBS_O_WORKDIR

###save machine list in file:
cat $PBS_NODEFILE > machines

cpu_id=` cat machines`
cpu_id=` echo $cpu_id | tr -t [:blank:] [,]`
###no we have comma seperated machine file list

###num processes
num_cpu=`cat machines | wc -l`

###starting cfx with HMPT:
cfx5solve -batch -def mydef.def -ccl myccl.ccl -parallel -par-dist $cpu_id -part ${num_cpu} -solver-double -start-method "HMPT MPI Distributed Parallel" > log 2>&1

FLUENT

For FLUENT we support a recent OPENMPI installation, which can be activated via -mpi=openmpi. A typicall batch script could look like this:

#!/bin/bash
###asking for 2 nodes for 20 minutes
#PBS -l select=2:mpiprocs=128
#PBS -l walltime=00:20:00
#PBS -N nameOfJob
#PBS -k eod

###load module
module load ansys/21.1

###change to the current working directory
cd $PBS_O_WORKDIR

###save machine list in file:
cat $PBS_NODEFILE > machines_orig
cat machines_orig | cut -d "." -f1 > machines

MPIPROCSPERNODE=128
awk -v NUM=$MPIPROCSPERNODE 'NR % NUM == 0' machines > machineslots


###num processes
NUMPROCS=`cat machines | wc -l`

###path to definition file
TXT=$PBS_O_WORKDIR/fluent-input.txt

###starting fluent with OpenMPI:
fluent 3ddp -mpi=openmpi -t${NUMPROCS} -cnf=machineslots -g -i $TXT > log 2>&1

SIEMENS

Please check via module environment (Module_environment(Hawk)), which versions are currently available for STAR-CCM+. A typical batch submission script example is given below.

STAR-CCM+

On HAWK we currently provide two methods to run STAR-CCM+ in parallel. One can choose between two methods:

  1. -mpidriver hpe is utilising MPT. For more details please see MPI(Hawk)
  2. -mpidriver openmpi uses a recent OpenMPI version.

A typical batch script could look like this:

#!/bin/bash
################start test
#PBS -l select=2:mpiprocs=128
#PBS -l walltime=01:00:00
#PBS -N nameofjob
#PBS -k oed

#module for academic usage only
module load siemens/lic
module load siemens/starccm/14.06.012-r8

cd $PBS_O_WORKDIR

np=$[ `wc -l <${PBS_NODEFILE}` ]

starccm+ -batch run -np $np -mpidriver hpe -batchsystem pbs mysimfile@meshed.sim >&outputrun.txt
# or ... -mpidriver openmpi ...

VULCAN

Please check beforehand via Application_software_packages, if you are allowed to use the installed ISV packages.

ANSYS

Please check via module environment (Module_environment(Hawk)), which versions are currently available. Typical batch submission script examples are given below.

CFX

On VULCAN you can choose between different parallel run options. One can choose between the following methods:

  1. -start-method "Intel MPI Distributed Parallel"
  2. -start-method "Open MPI Distributed Parallel" uses an OpenMPI version brought by ANSYS installation folder.

A typical batch script could look like this:

#!/bin/bash
### skylake example using 4 nodes with each: 40cores and 192gb of ram:
#PBS -l select=4:node_type=skl:node_type_mem=192gb:node_type_core=40c:mpiprocs=40,walltime=01:00:00
#PBS -N myjobname
#PBS -k eod

# load module
module load cae/ansys/19.3

# change into specific working directory
cd $PBS_O_WORKDIR

cat $PBS_NODEFILE > machines
cpu_id=` cat machines`
cpu_id=` echo $cpu_id | tr -t [:blank:] [,]`
#no we have comma seperated machine file list e.g. (n092902,n092902,n092902,n092902,n092902,n092902,n092902,n092902,n092902,n092902,n092902,...)

# starting cfx5solve:
cfx5solve -def my.def -batch -par -par-dist $cpu_id -start-method "Intel MPI Distributed Parallel"
