1. Make sure you have a workign version of OpenFOAM, or if you are using Ubuntu 14.04 or greater, the installer will download and install the proper version of OpenFOAM in steps 8-10. See the table below for the correct version of OpenFOAM for each version of HELYX-OS.

HELYX-OS Version	Compatable OpenFOAM Version
HELYX-OS v2.3.1	OpenFOAM-2.4.0

2. Download the latest 64 Bit binary from the project front page or from the list of releases. The installer will have the form:

   <date>-Engys-HELYX-OS-<version>--linux-x86_64-FULL.bin
   

3. Once the binary is downloaded, open a Linux terminal and navigate to the location of the newly downloaded HELYX-OS installer.

4. Change the permissions of the installer by executing chmod 755 <installer name> in the terminal, similar to:

   :~$ chmod 755 20160114-Engys-HELYX-OS-2.3.1--linux-x86_64-FULL.bin
   

5. Start the installer by typing ./<installer name> while in the terminal, similar to:

   :~$ ./20160114-Engys-HELYX-OS-2.3.1--linux-x86_64-FULL.bin
   

6. At this point, the installer will begin and the user will be guided through the installation process:

   For users with existing installations of OpenFOAM (see compatability table above), select to install only the GUI by typing 1 and hitting enter. To install the HELYX-OS GUI and the compatable version of OpenFOAM (for Ubuntu 14.04 or later only), type 2 and press enter.

9. The user will be prompted to enter the full path to where HELYX-OS will be intalled:

   Select destination folder for HELYX-OS GUI:
   

   For example, if a user named Scott wants to install HELYX-OS to their home folder (this is the suggested location), then they woudl enter:

   Select destination folder for HELYX-OS GUI: /home/scott/
   

   and a folder named Engys, containing HELYX-OS will be created in the user's home folder. The GUI will install and produce the following output:

   Select destination folder for HELYX-OS GUI: /home/scott
   Installing in: /home/scott
   Installing HELYX-OS GUI ................done.
   

10. If you previously selected option 2 in step 8, you will now be prompted to select your linux distribution:

    Please select your linux distribution:

    1. Ubuntu (14.04 or later)
    2. Other #?

Selecting **1** will install the compatable OpenFOAM deb package for 64 bit Ubuntu on 14.04 or later.  For other linux distributions, the compatable version of OpenFOAM must be installed manually by the user.

11. To start HELYX-OS in the terminal, execute the HELYX-OS.sh file located in engys/HELYX-OS/v2.3.1 directory similar to:

       :~$ ~/Engys/HELYX-OS/v2.3.1/HELYX-OS.sh
