HELYX-OS is an open-source Graphical User Interface designed to work natively with OpenFOAM version 4.1 and OpenFOAM v1606+. The GUI is developed by ENGYS using Java+VTK and delivered to the public under the GNU General Public License.

HELYX-OS has been created to facilitate the usage of the standard OpenFOAM libraries, by removing the complexity of text based case definition in favour of an intuitive easy-to-use graphical user interface. The GUI is focused on pre-processing tasks, including meshing, case definition and solver execution. Visit the HELYX-OS Project Page for more information.
