Designing an Efficient EV for the Shell Triple 10 Challenge
As battery electric vehicles (BEVs) continue to evolve, automotive manufacturers face a fundamental engineering challenge: how to improve range, charging performance and sustainability without relying solely on larger battery packs. For many years, increasing battery capacity provided a straightforward route to extending vehicle range. However, larger batteries introduce additional mass, higher material consumption and increased […]
Validating Marine Propeller Performance with HELYX CFD
In naval architecture and marine engineering, open-water curves, such as the thrust coefficient, torque coefficient and efficiency as functions of advance coefficient, are the primary hydrodynamic input to propeller and propulsion design. Capturing such quantities accurately through CFD modelling helps engineers take design decisions. This article takes part of our ongoing HELYX Validation and Verification […]

HELYX 4.5.1 is a maintenance release focused on bug fixes, stability improvements and code refinements to address known issues identified in previous versions. For more information, existing users should refer to […]
Aerodynamic Optimisation Using Adjoint CFD and Wind Tunnel Testing in Speed Skiing
The “Non-Motorized Skiing Speed World Record” measures the fastest speed reached on alpine skis using only natural forces, namely without any mechanical assistance. In particular, the Speed One (S1) record, which is the best class category, is performed with specific speed skiing equipment. All the periodic events where athletes compete for the world title and […]
CFD for Urban Pollutant Dispersion Validation Using HELYX
Urban pollutant dispersion CFD simulations are increasingly important for understanding air quality in dense urban environments. There is a critical need for accurate urban air quality simulation. Engineers and researchers rely on advanced CFD methodologies to evaluate pedestrian exposure, airflow behaviour, and contaminant transport around buildings. This article marks the first in our new HELYX […]
