Install ANSYS 18 on ubuntu (x64)

Posted October 23, 2018 at 14:53 by Abhishek_784

This is the step by step procedure that i followed to get ansys running on my machine. This procedure won't give any library issue.

The required packages from the installation guide (for RedHat/CentOS) are:
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
libXxf86vm.i686
libSM.i686
libXt.i686
xorg-x11-fonts-ISO8859-1-75dpi.noarch
glibc-2.12-1.166.el6_7.1 (or greater)

1. Therefore I installed:
Code:
sudo apt install xterm lsb csh ssh rpm xfonts-base xfonts-100dpi xfonts-100dpi-transcoded xfonts-75dpi xfonts-75dpi-transcoded xfonts-cyrillic libmotif-common mesa-utils libxm4 libxt6 libxext6 libxi6 libx11-6 libsm6 libice6 libxxf86vm1 libpng12-0 libpng16-16 libtiff5 gcc g++ libstdc++6 libstdc++5 libstdc++-5-dev

2. Install manually libXp (not included in the standard repo), you can find it at:
HTML Code:
https://pkgs.org/download/libxp6

3. Update the database with:
Code:
sudo updatedb

4. Locate the following libs and create soft links based on your system. I did as follows:
Code:
sudo ln -sf /usr/lib/x86_64-linux-gnu/mesa/libGL.so.1 /usr/lib/libGL.so
sudo ln -sf /usr/lib/x86_64-linux-gnu/mesa/libGL.so.1 /usr/lib/libGL.so.1
sudo ln -sf /usr/lib/x86_64-linux-gnu/libGLU.so.1 /usr/lib/libGLU.so
sudo ln -sf /usr/lib/x86_64-linux-gnu/libXm.so.4 /usr/lib/libXm.so
sudo ln -sf /usr/lib/x86_64-linux-gnu/libXm.so.4 /usr/lib/libXm.so.3
sudo ln -sf /usr/lib/x86_64-linux-gnu/libXp.so.6 /usr/lib/libXp.so
sudo ln -sf /usr/lib/x86_64-linux-gnu/libXt.so.6 /usr/lib/libXt.so
sudo ln -sf /usr/lib/x86_64-linux-gnu/libXext.so.6 /usr/lib/libXext.so
sudo ln -sf /usr/lib/x86_64-linux-gnu/libXi.so.6 /usr/lib/libXi.so
sudo ln -sf /usr/lib/x86_64-linux-gnu/libX11.so.6 /usr/lib/libX11.so
sudo ln -sf /usr/lib/x86_64-linux-gnu/libSM.so.6 /usr/lib/libSM.so
sudo ln -sf /usr/lib/x86_64-linux-gnu/libICE.so.6 /usr/lib/libICE.so
sudo ln -sf /lib/x86_64-linux-gnu/libgcc_s.so.1 /lib/libgcc.so
sudo ln -sf /lib/x86_64-linux-gnu/libc.so.6 /lib/libc.so
sudo ln -sf /lib/x86_64-linux-gnu/libc.so.6 /lib64/libc.so.6

5. Change the command interpreter for shell scripts:
Code:
sudo dpkg-reconfigure dash
Then answer "No" to the question.

6. From DVD1 install Ansys, launch:
Code:
sudo ./INSTALL

7. Modify the Linux environment variable ANSYS quick start of each component Modify the hidden files.Bashrc your Ubuntu home directory. Add the following code in.Bashrc. Method for typing in the terminal code: gedit ~/.bashrc
paste the following code:

# add environment variables:

#ANSYS

# Workbench
export ANSYS180_DIR=/ansys_inc/v180/ansys
alias wb2='/ansys_inc/v180/Framework/bin/Linux64/runwb2 -oglmesa'
export LD_LIBRARY_PATH=/usr/ansys_inc/v180/Framework/bin/Linux64/Mesa:$LD_LIBRARY_PATH
#export XLIB_SKIP_ARGB_VISUALS=1 #uncomment if you have trasparency issues in CFX pre/post or turbogrid
export LANG=en_US.UTF8

#CFX
export PATH=/ansys_inc/v180/CFX/bin:$PATH

#Turbogrid
export PATH=/ansys_inc/v180/TurboGrid/bin:$PATH

#FLUENT
export PATH=/ansys_inc/v180/fluent/bin:$PATH
export FLUENT_ARCH='lnamd64'

8. Type the following code:
source .bashrc

9. To start ansys use any of the following commands:
Ansys CFX Launcher

CFX5
CFX-pre

cfx5pre

cfx5-solve

cfdpost
Turborid

Ansys APDL

ansys180 # is really in command mode
Ansys180 -g # graphics mode
Ansys Workbench

runwb2
Use the get command to help command -help

Note: The Linux version of Ansys is installed in the Ubuntu is installed by default in /usr/ansys_inc. If you change the default installation location, please modify the path specified in the ansyslmd.ini. Use VIM to open ansyslmd.ini, as follows ANSYSLI_NOFLEX=1 LICKEYFIL=/usr/ansys_inc/shared_files/licensing/license.dat

If the fonts are not displayed correctly in gui, run the following: sudo apt-get install xfonts-75dpi xfonts-100dpi xterm ttf-mscorefonts-installer

You do need to restart your system (it might be enough to restart the X server)!
