SU2 is an open source CFD solver developed by the School of Aeronautics and Astronautics at Stanford University.

Download SU2 source code:

mkdir $HOME/su2code && cd $HOME/su2code
# Only clone the latest commit version to speed up downloading
git clone https://github.com/su2code/SU2.git --depth=1

Create a shared folder:

mkdir ${HOME}/LinuxShare

Edit the Samba configuration file /etc/samba/smb.conf:
