ENGYS, a global leader in open-source computational fluid dynamics (CFD) solutions, is pleased to announce the release of HELYX version 4.4.0. This new version delivers a wide range of improvements focused on boosting productivity, expanding modelling capabilities, and enhancing simulation performance.
This release also includes updated versions of the HELYX-Coupled, HELYX-Adjoint and HELYX-Marine add-ons, designed to take full advantage of the new features available in HELYX 4.4.0.
What’s New in HELYX 4.4.0?
Version 4.4.0 introduces several key additions and enhancements, including:
- Remote File Browser: browse remote files directly from the GUI via SSH, with full directory mounting for streamlined case setup.
- Enhanced Geometry Tools: import Rhino 3DM files; automatically split surfaces by feature angle; convert 3D surface files to 2D ribbons with the new CAD converter.
- Advanced Meshing Capabilities: new options for isotropic, anisotropic and cylindrical base meshes; new dedicated interface for 2D meshing; improved near-wall layer smoothing; enhanced patch preservation and snapping options for cleaner mesh generation.
- New Setup Features: added thermal boundary sources for modelling heat transfer for brake cooling simulations; new semi-implicit scalar sources with dynamic activation; new humidity sources for modelling vegetation; new porous media thermal models; enhanced pressure boundary conditions for VOF simulations.
- New Post-Processing Tools: new options to import external datasets (PVD, VTK, Ensight); expanded chart creation tools with algebraic expressions; enhanced turbomachinery performance monitoring capabilities; improved runtime visualization for faster and easier result analysis.
Solver & Performance Enhancements
In addition to the GUI updates, this release also includes several improvements to the existing solvers and meshing workflows:
- New reacting flow solver with full Unified Solver Framework (USF) support for advanced multi-physics simulations.
- Optimised steady-state multiphase solver with advanced cavitation models and extended statistical convergence assessment tool.
- Faster single-precision solver performance.
