Hi everybody,
since I had a lot of issues installing Ansys on Ubuntu, I summarize here all the steps (some picked up inside this forum) that are required to have a running version. I suggest to use standard MESA driver instead of nvidia or AMD drivers because I also need to use xrdp 0.9.4 (to have remote access) and it does not work with those drivers.

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. Since you have installled ANSYS as root, you need to change ownership of the ANSYS configuration directories and files so that you have write access to them (if "user" is your username):
Code:
sudo chown -R user:user ~/.ansys
sudo chown -R user:user ~/.config
sudo chown -R 777 /ansys_inc/v182/aisol/WBMWRegistry/

8. Debian-based multiarch distributions have their libc in /lib/x86_64-linux-gnu/ instead in /lib/. So that regular-expression for fetching the libc_version misses because of the two hyphens in x86_64-gnu-linux. After this modification everything seems to be fine...
Locate cfx5arch (probably /usr/ansys_inc/v182/CFX/bin/cfx5arch). In this file you will find near line 196:
Code:
if test -n "$libc_file"; then
case `basename $libc_file | sed 's/\.so//g'` in
glibc-*|libc-[0123].*) # this is almost certainly a glibc version
after that I added:
Code:
libc_file_tmp=`echo $libc_file | sed -e 's/x86_64-linux-gnu//g'`
and modified the following line from:
libc_version=`echo $libc_file | sed -e 's/^[^-]*-//' -e 's/\.so//g'`
to
Code:
libc_version=`echo $libc_file_tmp | sed -e 's/^[^-]*-//' -e 's/\.so//g'`
9.Since ptrace is used to monitor intelmpi CFX run, set the permission for all the users, just edit
PHP Code:
/etc/sysctl.d/10-kernel-hardening.conf 
and set:
Code:
kernel.yama.ptrace_scope = 0

10. Set the following environment variables in your .bashrc:
Code:
# Workbench
export ANSYS182_DIR=/ansys_inc/v182/ansys
alias wb2='/ansys_inc/v182/Framework/bin/Linux64/runwb2 -oglmesa' 
export LD_LIBRARY_PATH=/usr/ansys_inc/v182/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/v182/CFX/bin:$PATH

#Turbogrid
export PATH=/ansys_inc/v182/TurboGrid/bin:$PATH

#FLUENT
export PATH=/ansys_inc/v182/fluent/bin:$PATH
export FLUENT_ARCH='lnamd64'

Hi David,
thanks a lot for posting this walkthrough. It also works for Ansys 19.0 (on Ubuntu 16.04 LTS). Before following your guide I was unable to run CFX standalone or from workbench.
This was exactly the help I needed.

does anyone has an idea, why CFX opens normally, but Fluent doesn't? I have v190.

First of all, Lots of thank you to David Pasquale.
Secondly, for this issue:

For opening the application directly from terminal, I guess step 10, can be simplified

Open the bashrc file by,
Code:
sudo gedit ~/.bashrc
Then in the file, at end you can simply add these lines instead of step 10.

Code:
alias cfx191  = '/ansys_inc/v191/CFX/bin/cfx5'

alias fluent191  = '/ansys_inc/v191/fluent/bin/fluent'

alias workbench191  = '/ansys_inc/v191/Framework/bin/Linux64/runwb2'

alias cfx182  = '/ansys_inc/v182/CFX/bin/cfx5'

alias fluent182  = '/ansys_inc/v182/fluent/bin/fluent'

alias workbench182   = '/ansys_inc/v182/Framework/bin/Linux64/runwb2'

You can now, just type fluent182 for launching Fluent-18.2 version and like that.

Hey, thanks for the reply, but I don't have a problem with opening the programs. I think something went wrong with the installation. I reinstalled everything 3 times and I have the same problem: I can't find workbench and fluent crashed after the fluent launcher window.

The message I get:
Code:
/usr/ansys_inc/v190/fluent/fluent19.0.0/bin/fluent -r19.0.0
/usr/ansys_inc/v190/fluent/fluent19.0.0/bin/fluent -r19.0.0 3d -nm -ssh
/usr/ansys_inc/v190/fluent/fluent19.0.0/cortex/lnamd64/cortex.19.0.0 -f fluent -nm (fluent "3d -pshmem  -host -alnamd64 -r19.0.0 -t1 -mpi=ibmmpi -path/usr/ansys_inc/v190/fluent -ssh")
/usr/ansys_inc/v190/fluent/fluent19.0.0/cortex/lnamd64/cortex.19.0.0: symbol lookup error: /usr/ansys_inc/v190/fluent/fluent19.0.0/lnamd64/syslib/libsvml.so: undefined symbol: __intel_cpu_feature_indicator_x
Does anyone have a solution to this?

Dear Zigec,

In Ansys there is a separate folder for workbench /v191/Framework/

Thanks

Hi everyone,


Has anyone who followed this guide had any issues with running CFX in parallel? My set up will perform the parallel calculations just fine using the Intel MPI local parallel method, but then will never write the results file and simply hang indefinitely. I am sure it is an issue with the set up as I have tested it on a number of test cases.


Thank you for any help you can give.


Regards,
James

Hy everyone,

nice description, it was truly helpful. However I recently upgraded my Ubuntu system from 16.04 to 18.04 and the ansys installation just stops around 90%. The last information in the log file is:


Quote:
Generating daemon scripts for this installation.
AWPROOTDIR = /usr/ansys_inc/v182
Creating RSM Launcher script ...
Created service script: rsmlauncher


AWPROOTDIR = /usr/ansys_inc/v182
Creating ANSYS RSM Cluster Master Service script ...
Created service script: arcmaster


AWPROOTDIR = /usr/ansys_inc/v182
Creating ANSYS RSM Cluster Node Service script ...
Created service script: arcnode

Has anyone met anything similar?

Thanks,
Richard

thanks for the solution, it works perfectly!

regarding designModeler and ansys not compeleting installation, I have gone through the AnsConfigWB.sh and .workbench.sh script...it seems that even though I have installed libpng12 from xenial package, ansys is still using libpng16 and that is the problem...

tried re-directing a soft link for libpng.so to libpng12 with no luck...
Also I have compiled and installed bash 4.3.30 form ubuntu 16.04 which also didn't fixed the problem...

so my guess is that libpng16 is the problem here as the script stucks here:

Code:
./workbench -cmd $exeFiles regServer -B

Hi,

Were you able to solve the issue? I am having the same problem with Linux Mint!

Please let me know, if you or anyone else has been able to solve the issue.
