    ENGYS Releases ELEMENTS 3.3.1 for Automotive CFD Design

    LONDON, UK, Apr 21, 2021 – ENGYS is pleased to announce the new release of ELEMENTS 3.3.1, an open-source based CFD software suite for vehicle design applications produced by Streamline Solutions LLC. This release also includes new versions of the add-on modules ELEMENTS-Adjoint and ELEMENTS-Coupled.

    ELEMENTS combines two simulation environments in one package: a dedicated virtual wind tunnel wizard for modelling external vehicle aerodynamics, and a general purpose CFD interface for solving other vehicle design applications (e.g. UHMT, HVAC, in-cabin flows, aeroacoustics, etc). The default methodology and best practices for external vehicle aerodynamics provided with this version of ELEMENTS have been widely tested and validated to conform to the latest regulations on alternative drag prediction methods proposed as part of the Worldwide harmonized Light vehicles Test Procedure (WLTP).

    ELEMENTS 3.3.1 offers a wide range of extended capabilities and several refinements to remove known issues found in the previous release 3.3.0. Some of the new exciting features added in this version include:

    1. Extended Python based journaling system for batch automation to cover all components in ELEMENTS, including the virtual wind tunnel wizard for external aerodynamics calculations.
    2. Improved meshing, including better layer addition for low-Re meshes, faster mesh creation by refactoring the snapping stage, increased robustness of crack detection in geometries, better snapping at sharp edges, etc.
    3. New boundary conditions, including a new porous baffle and a complete refactoring of the arbitrary mesh interfaces (AMI).
    4. New fields mapping tool for efficient mapping of solutions between different computational grids.
    5. Added support for relative rigid multibody motion using generalised internal boundaries (GIB).
    6. New local GPU rendering option for remote client-server connections.
    7. New emake build system based on the industry standard cmake. This is now the default build system for HELYX-Core.
    8. Aero: added new option to the configuration files to selectively exclude assembly types from the computation of vehicle width.
    9. Aero: improved report functionalities, including the ability to add vector plots and the inclusion of dimensional units for data and legends.
    10. ELEMENTS-Adjoint: new symmetry condition for adjoint sensitivities around a user-defined plane.
    11. ELEMENTS-Coupled: added caching of block coupled AMG agglomeration for improved solver performance.
