ENGYS Releases HELYX Version 4.4.0

ENGYS, a company providing open-source computational fluid dynamics (CFD) solutions, has released HELYX version 4.4.0. This new version delivers improvements focused on expanding productivity, modelling capabilities, and simulation performance, according to ENGYS.

This release includes updated versions of the HELYX-Coupled, HELYX-Adjoint and HELYX-Marine add-ons.

What’s New in HELYX 4.4.0?

Version 4.4.0 introduces several additions and enhancements:

• 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 and Performance Enhancements

There are 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.
• Optimized steady-state multiphase solver with advanced cavitation models and extended statistical convergence assessment tool.
• Faster single-precision solver performance.
