Streamline Solutions launches ELEMENTS v2.4.0

28th November 2017:

Streamline Solutions is pleased to announce the release v2.4.0 of ELEMENTS, an open-source based CFD software suite for vehicle design applications.


The product combines two simulation environments in one package: a dedicated wizard type interface 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, soiling, etc). The automated methodology for external vehicle aerodynamics provided with 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).


The new release of ELEMENTS incorporates several improvements and new features with respect to v2.3.0 to enable the user to:

  • Reduce setup times using a wide range of new useful features in the GUI, such as automatic assignment of vehicle parts based on the CAD file prefix name, or a new calculator tool to determine the axis and center of rotation of a given component.
  • Model rotating wheels via wheel velocity boundary, MRF or sliding interface options.
  • Simplify tractor trailer simulations by specifying wheel axles.
  • Improve simulation results in HPC systems with new solver default settings and numerical schemes to mitigate decomposition inconsistency issues.
  • Create new custom modelling configurations to simulate any vehicle geometry and wind tunnel type from the GUI.
  • Perform better topology and shape optimization studies with an up-to-date version of the ELEMENTS-Adjoint add-on module.

The latest installation files for both Linux and Windows are now available for download to all ELEMENTS customers from our Customer Portal at
