ENGYS, a global leader in open-source computational fluid dynamics (CFD) solutions, is pleased to announce the release of HELYX version 4.5.0. This new version introduces a new multi-physics workflow, alongside improvements in usability, meshing and post-processing 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 4.5.0.
What’s New in HELYX 4.5.0?
Version 4.5.0 introduces several key additions and enhancements, including:
• New Multi-Physics Interface: modular GUI modelling framework to combine different physics and solver settings on multi-region meshes, in line with the Unified Solver Framework.
• Enhanced Meshing Capabilities: improved boundary layer control, support for reference frames in mesh generation, feature-based refinement directly from geometry, and combined surface and volumetric refinements.
• Improved Usability and Workflow: new view cube for navigation, enhanced plane widget with interactive rotation and translation, surface picker and highlight tools, and improved list management for probes and material points.
• Advanced Post-Processing Tools: new native case reader for faster case loading, multi-slice and multi-isosurface capabilities, and streamline generation on surface patches.
• Expanded Modelling Features: added GUI support for cavitation models, solar radiation with time-dependent inputs and local transmissivity, and improved handling of non-conformal interfaces (NCC).
Solver & Performance Enhancements
In addition to the GUI updates, version 4.5.0 also includes several improvements to the existing solvers and workflows:
• Faster Meshing Performance: approximately 20% improvement in CPU time, with reduced memory usage.
• Accelerated Post-Processing: up to 4x faster case loading and up to 75% reduction in memory consumption with the new case reader.
• Improved Numerical Methods: enhancements in solver stability, mesh decomposition, and handling of complex multi-physics simulations.
