LONDON, UK, Apr 10, 2026 – ENGYS is proud to announce the release of ELEMENTS version 4.5.0, an open-source CFD software suite tailored for automotive design applications, distributed by Streamline Solutions LLC.
This release introduces a new multi-physics workflow, alongside improvements in usability, meshing and post-processing performance, with a focus on simplifying the setup and analysis of complex automotive simulations.
Updated versions of the ELEMENTS-Adjoint and ELEMENTS-Coupled modules are also included, aligned with the new capabilities available in ELEMENTS 4.5.0.
What’s New in ELEMENTS 4.5.0?
Version 4.5.0 introduces several key additions and enhancements, including:
Improved Simulation Workflow
- New Multi-Physics Interface: define different physics and solver settings on different mesh regions, enabling more flexible modelling of complex vehicle scenarios.
- Modular Modelling Environment: refactored setup interface with clearer structure and improved navigation, making it easier to configure and manage simulations.
Enhanced Meshing and Performance
- Faster Meshing Performance: approximately 20% improvement in meshing speed with reduced memory usage.
- Improved Mesh Control: better handling of boundary layers, feature-based refinement, and support for reference frames in mesh generation.
- Flexible Mesh Operations: combined surface and volumetric refinement, and improved mesh splitting workflows.
Faster Post-Processing and Analysis
- New Native Case Reader: up to 4x faster post-processing with significantly reduced memory usage.
- Advanced Visualisation Tools: multi-slice and multi-isosurface generation, streamline visualisation on surfaces, and direct export to PVD format.
Improved Usability Across the GUI
• New view cube for intuitive navigation.
• Interactive plane manipulation for faster analysis.
• Surface selection and highlighting tools for easier setup.
• Improved management of probes and material points.
Expanded Modelling Capabilities
• Solar radiation with time-dependent inputs and local transmissivity.
• Improved handling of partially overlapping non-conformal interfaces (NCC).
• Additional field processing tools for pressure analysis.
