Installing Abaqus 6.13-4 on Ubuntu Linux

Pre-installation

First, install csh. That’s because the default shell that Abaqus installer use is csh.
```
$ sudo apt install csh tcsh
```

Create link for necessary C libraries

$ sudo ln -s /lib/i386-linux-gnu/libc.so.6 /lib/libc.so.6

$ sudo ln -s /lib/x86_64-linux-gnu/libc.so.6 /lib/libc.so.6

Install libjpeg62, libstdc++5 and xfonts-75dpi if not installed

$ sudo apt install libjpeg62 libstdc++5 xfonts-75dpi

Installation

Install License Server following the manual
Install Abaqus following the manual

Post-installation

Create link for temporary files
```
$ sudo ln -s /tmp /usr/tmp
```

Create alias for running license manager

alias lm="/opt/abaqus/License/lmgrd -c /opt/abaqus/License/abq6134.dat -l /tmp/abq6134.log"

Set the environment variable export XLIB_SKIP_ARGB_VISUALS=1 in .profile or make alias
```
alias abaqus="XLIB_SKIP_ARGB_VISUALS=1 /opt/abaqus/Commands/abaqus"
```
If hardware acceleration is unnecessary, one can run Abaqus/CAE by
```
$ abaqus cae -mesa
```

If hardware acceleration is needed, one needs to modify /usr/bin/Xorg at one’s own risk:

#!/bin/sh
#
# Execute Xorg.wrap if it exists otherwise execute Xorg directly.
# This allows distros to put the suid wrapper in a separate package.

basedir=/usr/lib/xorg-server
if [ -x "$basedir"/Xorg.wrap ]; then
    exec "$basedir"/Xorg.wrap "$@"
else
    exec "$basedir"/Xorg "$@" +iglx
fi

This is because newer version of Xorg has disabled indirect OpenGL rendering.

An alternative way is install libosmesa6, which is actually pointing to a newer version.

$ sudo apt install libosmesa6

Or one may use an older version of the libraries provided by Abaqus:

ABQLIB=/opt/abaqus/6.13-4/code/bin/SMAExternal/mesa/full
export LD_LIBRARY_PATH=$ABQLIB:$LD_LIBRARY_PATH
