ENGYS Releases HELYX V3.3.1 Open-Source CFD for Enterprise

LONDON, UK, Apr 9, 2021 – ENGYS is delighted to announce the release v3.3.1 of HELYX, a general-purpose Computational Fluid Dynamics (CFD) software solution for engineering design and optimisation based on ENGYS’ own open-source simulation engine (HELYX-Core). The new release also includes updates for all of HELYX’s add-on solver modules, namely: Adjoint, Coupled, Marine and Hydro.




HELYX 3.3.1 offers a wide range of extended capabilities and several refinements to remove known issues found in the previous release 3.3.0. Some of the new exciting features added in this version include:

  1. Expanded support for Python journaling in the GUI to cover the entire scope of features available in HELYX and associated add-ons.
  2. Improved meshing, including: better layer insertion for low y+ meshes, speed-up of the snapping stage, better crack detection in poor geometries, better snapping at sharp edges, etc.
  3. New porous baffle boundary condition as an option for cyclic and cyclic AMI type boundaries.
  4. New fields mapping tool with increased performance and robustness. Ideal for mapping results efficiently between two different models.
  5. New local rendering option in the GUI to display and interact with a case located on a remote server machine using the local machine’s graphics card.
  6. New discrete execution scripts in the GUI for both Linux and Windows machines. This allows the user to create a case on one operating system and submit it for execution on a machine running a different one.
  7. New emake build system based on the industry standard cmake. This is now the default HELYX-Core build system.
  8. Added support for multiple moving bodies in relative motion using GIB’s (e.g. valves and piston moving inside an internal combustion engine).
  9. New (beta) periodic sector mesh interface capability for accelerated turbomachinery and rotating machinery calculations.
  10. New (beta) multi-direction wind-comfort assessment solver with added support for new multi-instancing technology (i.e. run multiple variations of the same case within a single case folder structure).
  11. Deprecation of end-of-life Linux distros: CentOS 6, Ubuntu 16, SLES 11, SLES 12 (SP3) and SLES 12 (SP4).
