LONDON, UK, Nov 3, 2021 – ENGYS is delighted to announce the release 3.4.0 of HELYX, a general-purpose Computational Fluid Dynamics (CFD) software solution for engineering design and optimization 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 3.4.0 offers a wide range of extended capabilities and code refinements to remove known issues found in the previous release 3.3.2. Some of the new exciting features added in this version include:

1. Mesh: New interactive histogram to display mesh quality metrics in the GUI.
2. Mesh: Improved feature edge snapping for modelling low y+ scenarios with near-wall layers.
3. Mesh: Improved accuracy and reduced turnaround times for mesh optimisation during the layer addition stage.
4. Setup: Added support for multi-body rigid motion and thermal solvers for Generalised Internal Boundaries (GIBs).
5. Setup: New boundary conditions, including a new synthetic turbulence generator based on the Turbulent Spot Method with Anisotropic Vorton (ATSM) and a new Delaunay triangulation method for time-varying point data at inlets.
6. Setup: Added support for new ω-equation based transition and SST curvature correction turbulence models.
7. Setup: New and improved thermal comfort outputs based on ISO7243 and ISO7730.
8. Solver: Added support for single-phase, compressible flows in the Unified Solver Framework (USF) via the GUI.
9. Solver: Improved USF implementation for single-phase, compressible, buoyancy driven flows.
10. Solver: New multi-species, drift-flux solver for modelling settling of solid particles or gas bubbles in liquids.
11. View: Upgraded graphic libraries in the GUI for improved local and remote image rendering.
12. View: Improved GPU-based rendering performed at client side for remote client-server GUI connections.
13. View: New export of display scenes and view objects to 3D formats such a X3D, PLY and VT.
14. HELYX-Adjoint: New enhanced symmetry of adjoint sensitivities around a user-defined plane.
15. HELYX-Adjoint: Improved convergence of adjoint sensitivities for topology optimisation.
16. HELYX-Coupled: New block-coupled adjoint implementation for massive speed up of sensitivity calculations w.r.t. standard adjoint solver segregated approach.
17. HELYX-Marine: New validated calm-water prediction method for both displacement and planning hulls using Adaptive Mesh Refinement (AMR).
