Gfortran/gcc
Gnuplot
Python interpreter version V2.6 or greater

Installation of FLUKA

In order to be able to download FLUKA from the FLUKA website it is mandatory to be registered as FLUKA user. Follow the registration process at FLUKA User Registration and Download (Public email providers are blocked, so use your UiB email or other institutional email-address) Then download your FLUKA package of choice from FLUKA Download, most likely you will want the latest flukaXXXX.XX-linux-gfor64bitAA.tar.gz package.

Install flukaxxxx-xx-linux-gfor64bitAA.tar.gz by creating the FLUKA folder and unpacking the package contents to it:

$ mkdir Fluka #create Fluka directory at your location of choice
$ mv Downloads/fluka.... Fluka/ #move downloaded tar.gz file to your newly created FLUKA folder
$ cd /pathto/FLUKA #enter the FLUKA folder
$ tar –xzvf fluka..... # Unpack installation file
$ make #(this creates the default executable flukahp and compiles auxiliary programs in the directory flutil)

Once installed, set some environmental variables at the end of your .bashrc file: (Type gedit .bashrc in your terminal to open and edit this file using gedit, or some other text editing software you wish to use)

export FLUPRO=/pathto/FLUKA #Path to the FLUKA folder where you installed FLUKA
export FLUFOR=gfortran #We use the gfortran version of FLUKA

Installation of flair and flair-geoviewer

Download the latest version of flair and flair-geoviewer from flair/download Most likely you will want the tar-gzip files:

flair-X.X-X.tgz
flair-geoviewer-X.X-X.tgz

When downloaded, expand the files to a temporary directory and enter this directory for installation

$ tar zxvf-flair-X.X-X.tgz
$ cd /pathto/flair-X.X-X #Path to the temporary directory just created
$ make install DESTDIR=/pathto/flair #install flair to a folder (named flair) of your choosing, preferably next to the FLUKA directory

Then delete the temporary flair-X.X-X directory. You can add an environment variable to your .bashrc to easily run flair from the command line, e.g.:

export PATH=$PATH:/pathto/flair #add this to the bottom of your .bashrc file and you can just type flair in the command line to start flair

To install flair-geoviewer you do the the same process again with the flair-geoviewer-x.xx-x.tgz file

$ tar xzvf flair-geoviewer-X.X-X.tgz #expand to a temporary directory
$ cd flair-geoviewer-X.X-X #enter the temproary directory
$ make
$ make DESTDIR=/pathto/flair install #OBS! DESTDIR=the folder where flair is installed!

Then delete the temporary directory and try to run flair!

$ flair

You should now be greeted by flair:
