HELYX is a comprehensive general purpose computational fluid dynamics (CFD) software package for engineering analysis and design optimisation of enterprise applications, based on ENGYS's own open-source CFD simulation engine.

ENGYS took advantage of their extensive experience developing and exploiting open-source CFD solutions to offer a unique product that combines the best of two worlds: the proven capabilities, support and reliability of commercial tools with the inherent advantages of cost-effective, scalable open-source software.

WHAT'S IN THE BOX?

HELYX is a unified, off-the-shelf CFD software product compatible with most Linux and Windows platforms, including high-performance computing systems. In addition to the base software components delivered for installation (HELYX-GUI and HELYX-Core), the package also incorporates an extensive set of ancillary services to facilitate the deployment and usage of the software in any working environment.

HELYX features an advanced hex-dominant automatic mesh algorithm with polyhedra support which can run in parallel to generate large computational grids. The solver technology is based on the standard finite-volume approach, covering a wide range of physical models: single- and multi-phase turbulent flows (RANS, URANS, DES, LES), thermal flows with natural/forced convection, thermal/solar radiation, incompressible and compressible flow solutions, etc. In addition to these, we have developed a Generalised Internal Boundaries (GIB) method to support complex boundary motions inside the finite-volume mesh. The standard capabilities of HELYX can also be expanded with the HELYX-ADD-ONS extension modules to cover more specialised applications.

The following components are delivered with HELYX as standard:

HELYX-GUI: our easy-to-use Graphical User Interface with client-server support for remote and cloud-based operation.
HELYX-Core: our very own advanced open-source CFD simulation engine developed using the OpenFOAM libraries and other open-source technologies.
User Support: our first-class help line to cover all technical questions and application queries related to HELYX.
Code Maintenance: regular software updates and upgrades delivered by ENGYS to enhance both HELYX-GUI and HELYX-Core.
Documentation: comprehensive written user's guide, tutorials guide, installation instructions and release notes to aid the user with HELYX.
