I. RHEL 6.4

Download and install RHEL 6.4 as a desktop Set username to Nicholas to allow research license for university Register redhat with wget command:

# wget -qO - https://rhnss.usyd.edu.au/pub/bootstrap/bootstrap_updates-only.sh | /bin/bash

Install additional libraries required by ANSYS, given in ansysPackages.sh (command is repeated below):

yum -y install libXp.x86_64 xorg-x11-fonts-cyrillic.noarch xterm.x86_64 openmotif.x86_64

compat-libstdc++-33.x86_64 libstdc++.x86_64 libstdc++.i686 gcc-c++.x86_64

compat-libstdc++-33.i686 libstdc++-devel.x86_64 libstdc++-devel.i686 compat-gcc-34.x86_64

gtk2.i686 libSM.i686 xorg-x11-fonts-ISO8859-1-75dpi.noarch

Update and upgrade RHEL with:

yum upgrade

yum install

Perform all security updates. Run ANSYS install as root - note you will need to allow TCP: do this by altering /etc/gdm/custom.conf

[xdmcp]

Enable=true

[security]

DisallowTCP=false

AllowRemoteRoot=true

And then run init 3 and init 5 commands (must be done as root)

Must alter .bash profile in user home to include ansys paths and ld libraries:

# .bash_profile

# Get the aliases and functions

if [ -f ~/.bashrc ]; then

. ~/.bashrc

fi

# User specific environment and startup programs

PATH=$PATH:$HOME/bin

export PATH

PATH=$PATH:/usr/ansys_inc/v150/Framework/bin/Linux64:/usr/ansys_inc/v150/aisol/lib/linx64:

export LD_LIBRARY_PATH

May also want to add ifup eth0 to the bash profile to connect to the internet automatically on startup.

Must add ansLib.conf to /etc/ld.conf.d/ folder to have ansys library dependencies resolved:

/usr/ansys_inc/v150/Framework/bin/Linux64:

/usr/ansys_inc/v150/commonfiles/MainWin/linx64/mw/lib-amd64_linux_optimized

Should be good to go!

II. System Coupling Command Line Run

Set up directory structure with fluid, structural and coupling subdirectories (make sure fluid.cas iscopied into fluid sub-directory).

Generate fluent journal file for case and place in main coupling directory, something along the lines of:

file/start-transcript "Solution 1.trn"

file set-batch-options , yes ,

file/read-case/fluidFlow.cas

s i i

(sc-solve)

wcd FLUENTRestart.cas.gz

exit

ok

In coupling directory:

/ansys_inc/v150/aisol/.workbench -cmd ansys.services.systemcoupling.exe

-inputFile ../coupling.sci

Check the scServer file to extract port, host and solution order In fluid directory:

/ansys_inc/v150/fluent/bin/fluent 3ddp -g -driver null -scport=xxxxx

-schost=pcd-14-139.aeromech.usyd.edu.au -scname=Solution 1

-i ../fluidFlow.jou > FLUENT.out

Note that after -g may not require -driver null

In structural directory:

/ansys_inc/v150/ansys/bin/ansys150 -b -scport xxxxx

-schost pcd-14-139.aeromech.usyd.edu.au

-scname "Solution" < ../structural.dat > ANSYS.out
