Streamline Solutions launches ELEMENTS v3.3.0

13th November 2020:

Streamline Solutions is delighted to announce the new release of ELEMENTS v3.3.0, an open-source based CFD software suite for vehicle design applications produced by Streamline Solutions LLC.


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 3.3.0 offers a wide range of extended capabilities and several refinements to remove known issues found in the previous release 3.2.1. Some of the new exciting features added in this version include:

  • Aero: Added support for fully automated Generalised Reference Frame (GRF) approach for modelling rotating grooved tyres (both in GUI and template files).
  • Aero: Refactoring of report batch execution tool with improved memory handling.
  • Aero: Enhanced report layout, including new table format, improved image quality and document bookmarks.
  • Aero: New drag and lift development charts added to automatic report tool.
  • Mesh: New Hybrid algorithm with improved near-wall layer mesh generation capabilities.
  • Setup: New interface for Generalised Internal Boundaries (GIB), including support for multiple GIB dynamic mesh motion models.
  • Setup: Improved Thermal Comfort tool with new human thermal comfort metrics based on ANSI-ASHRAE-55:2017, ISO 7730:2005, ISO 7933:2004 and UTCI.
  • View: New Runtime Visualisation option to save images during solution runtime based on an existing View Scene.
  • View: New objects for visualisation and improved usability (e.g. Threshold, etc.).
  • ELEMENTS-Coupled: Extended GUI support for new pressure-based, block-coupled, incompressible flow solver.
  • ELEMENTS-Coupled: Extended GUI support for new density-based, block-coupled, compressible flow solver (subsonic, transonic and supersonic flow regimes).
  • General: New STL reader for faster geometry loading when used in combination with OpenGL rendering back-end on local machines.
  • General: New high-performance OpenGL rendering back-end rendering and refactoring of software parallel rendering.
  • General: New selective case loading. User can decide to load at startup any combination of the following: Surface/Volume Mesh (inc. Zones) and/or Geometry.
  • General: New interface for Slurm batch scheduling system. General: New built-in MPI v4 options for faster solution turnaround times.
