HELYX is a comprehensive general purpose computational fluid dynamics (CFD) software package for engineering analysis and design optimisation of enterprise applications, based on ENGYS’ own open-source CFD simulation engine.
It take Advantage of this 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.
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, a generalized internal boundary method (GIB) has been developed to support complex boundary movements within the finite volume mesh. HELYX’s standard capabilities can also be extended with HELYX-ADD-ONS expansion modules to cover more specialized applications.
