💥💥💥 What is Helyx-OS and what is used for ?

Helyx-OS is an open-source graphical user interface (GUI) for OpenFOAM, a free and open-source computational fluid dynamics (CFD) software¹. It allows users to perform pre-processing tasks such as meshing, case definition and solver execution. It supports both OpenFOAM and OpenFOAM+, and works on Linux and Windows platforms².

Helyx-OS is designed 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. It is intended for academic use and entry-level CFD work¹. If you are looking for an enterprise CFD solution for industrial applications, you can check out HELYX, a more advanced CFD software product developed by ENGYS³.

Is Helyx-os completely free?

Yes, Helyx-OS is completely free for academic use and entry-level CFD work. It is released to the public under the GNU General Public License¹. However, if you are looking for an enterprise CFD solution for industrial applications, or if you require technical support and/or training for Helyx-OS and OpenFOAM, you may need to pay for those services². You can contact ENGYS, the developer of Helyx-OS, for more information³.

Can I use Helyx-OS for commercial purposes?

According to the developer of Helyx-OS, ENGYS, the software is intended for academic use and entry-level CFD work, and it is delivered to the public under the GNU General Public License¹. This means that you can use Helyx-OS for commercial purposes, as long as you comply with the terms and conditions of the license². However, you may not receive any technical support or documentation from ENGYS, unless you pay for those services¹. If you are looking for an enterprise CFD solution for industrial applications, you may want to consider HELYX, a more advanced CFD software product developed by ENGYS³. HELYX is not free, but it offers more features, reliability and support than Helyx-OS².

What is difference between Helyx-os  and HELYX ?

The main difference between Helyx-OS and HELYX is that Helyx-OS is an open-source graphical user interface (GUI) for OpenFOAM, a free and open-source computational fluid dynamics (CFD) software, while HELYX is a comprehensive general purpose CFD software package for engineering analysis and design optimisation of enterprise applications, based on ENGYS’ own open-source CFD simulation engine¹².

Helyx-OS is intended for academic use and entry-level CFD work, and it is delivered to the public under the GNU General Public License. It supports both OpenFOAM and OpenFOAM+, and works on Linux and Windows platforms. It allows users to perform pre-processing tasks such as meshing, case definition and solver execution. It does not provide any technical support or documentation from ENGYS, unless users pay for those services¹³.

HELYX is a unified, off-the-shelf CFD software product compatible with most Linux and Windows platforms, including high-performance computing systems. It features an advanced hex-dominant automatic mesh algorithm with polyhedra support, a wide range of physical models, and a Generalised Internal Boundaries method to support complex boundary motions. It also incorporates an extensive set of ancillary services to facilitate the deployment and usage of the software in any working environment. It offers more features, reliability and support than Helyx-OS, but it is not free²⁴.

Can I modify Helyx-OS for my own purposes?

Yes, you can modify Helyx-OS for your own purposes, as long as you comply with the terms and conditions of the GNU General Public License¹. Helyx-OS is an open-source graphical user interface (GUI) for OpenFOAM, a free and open-source computational fluid dynamics (CFD) software². The source code of Helyx-OS is available on GitHub³, where you can also find instructions on how to compile it on your own⁴. However, if you modify Helyx-OS, you may not receive any technical support or documentation from ENGYS, the developer of Helyx-OS, unless you pay for those services². You may also want to check out the FAQ page of Helyx-OS for more information.

What is difference in functionaity between Helyx-os and HELYX for CFD simulations ?

The difference in functionality between Helyx-OS and HELYX for CFD simulations is mainly related to the following aspects:

• Meshing: Helyx-OS uses SnappyHexMesh, an automatic mesh generator for complex geometries based on hexahedral cells¹. HELYX uses an advanced hex-dominant automatic mesh algorithm with polyhedra support, which can run in parallel and generate large computational grids².
• Solvers: Helyx-OS supports a subset of solvers and boundary conditions available in OpenFOAM, a free and open-source CFD software¹. HELYX supports a wide range of physical models, such as single- and multi-phase turbulent flows, thermal flows, radiation, compressible and incompressible flows, etc. It also incorporates a Generalised Internal Boundaries method to handle complex boundary motions².
• GUI: Helyx-OS provides a graphical user interface (GUI) for pre-processing tasks such as meshing, case definition and solver execution. It also allows users to monitor the simulation progress and visualize the results¹. HELYX provides a more comprehensive and user-friendly GUI, with client-server support for remote and cloud-based operation. It also offers more features and options for case setup, simulation control and post-processing².
• Support: Helyx-OS is delivered to the public under the GNU General Public License, and does not provide any technical support or documentation from ENGYS, the developer of Helyx-OS, unless users pay for those services¹. HELYX is a commercial product, and provides first-class user support, code maintenance and documentation from ENGYS².

In summary, Helyx-OS is a free and open-source GUI for OpenFOAM, intended for academic use and entry-level CFD work. HELYX is a comprehensive and cost-effective CFD software package for engineering analysis and design optimisation of enterprise applications, based on ENGYS’ own open-source CFD simulation engine.
