OpenFOAM & HELYX Training Course

During this 2-day training, the participants will be introduced to the open-source CFD technology OpenFOAM® using HELYX-OS. The most commonly used CFD solver capabilities of OpenFOAM® will be explored, combined with an in-depth look in the structure of the Computational Fluid Dynamics Library, which forms the base of all OpenFOAM® fluid flow solvers. The open-source native GUI HELYX-OS, developed by Engys Ltd. will be used extensively.


This OpenFOAM®/HELYX-OS training course aims to achieve the following goals:

  • Getting started and become familiar with the OpenFOAM® framework, commonly used solvers and relevant industrial examples.
  • Learn to use the open-source Graphical User Interface HELYX-OS as the native front-end for OpenFOAM®.


The participants will be introduced to fluid dynamics and corresponding CFD methods and solvers that are available in OpenFOAM®. The front-end software package HELYX-OS will be introduced and extensively used to model and analyze industrial case studies in different fields such as incompressible/compressible flows, heat transfer and multiphase flows.


The training course material has been developed by Engys Ltd. (the developers of HELYX-OS) and will be presented by one of the DRG consultants who actively uses OpenFOAM® and HELYX-OS within their project work.

Intended for:

The training course is intended for engineers involved in fluid flows and heat transfer problems in industry that are considering or using OpenFOAM®.



Basic theoretical background on flow and heat transfer mechanisms is preferable.
