Open-source GUI for OpenFOAM


HELYX-OS is an open-source graphical user interface (GUI) designed by ENGYS to work natively with the standard OpenFOAM libraries provided by the OpenFOAM Foundation and ESI-OpenCFD. The GUI is intended for academic use and entry-level CFD work, and it is delivered to the public under the GNU General Public License.

If you are looking instead for an enterprise CFD solution for industrial applications, please refer to our advanced CFD software product HELYX.

Why use HELYX-OS?

HELYX-OS was created by ENGYS to facilitate the usage of standard OpenFOAM by removing the long and complex manual text inputs required by the utilities and solvers in this code. The GUI provides a fully interactive, easy-to-use environment to perform all pre-processing tasks in the CFD process, including meshing, case definition and solver execution.

The main features of HELYX-OS can be summarised as follows:

Native support for both OpenFOAM and OpenFOAM+: load existing cases by reading settings directly from the available project text files.
Linux and Windows platforms (n.b. Windows version available to paid support customers only).
One file installation: deploy HELYX-OS and OpenFOAM in your system in one go.
Control the mesh utility snappyHexMesh, including geometry display and execution within the GUI.
Comprehensive case definition module, including controls for physical models, turbulence, boundary conditions and field initialisation.
Solver execution tab with solution residuals monitoring.
Cloud computing interface for execution of OpenFOAM via the HELYX-OS Cloud connection powered by Parallel Works.
