Simulating the “Porpoising” Phenomenon Using HELYX
Amongst the most significant changes that the 2022 FIA regulations brought to Formula 1 are those directly related to the aerodynamic design of the car. With attention focused on the revolutionary 3D-contoured underfloor, the teams now heavily rely on its efficient design to produce the majority of the car’s total downforce. This new tunnel-style underfloor, […]
HVAC CFD Simulation of Airborne Transmission in Classrooms
The global pandemic has highlighted the importance of indoor air quality and how innovative ventilation strategies can reduce the spread of diseases, saving lives. According to the Centers for Disease Control and Prevention (CDC), COVID-19, along with diseases such as tuberculosis, measles and chicken pox, predominantly spread by airborne transmission. This is where small droplets […]

How CFD Can Help Meet Dam Safety Regulations
Although the probability of a dam failure is often low, the consequences of one can be catastrophic. In the US, since 1980, there have been on average 24 dam failures per year, with overtopping the most common cause. Overtopping is where excess river flow causes the water level to spill over the top of the […]
Benchmarking CFD for External Aerodynamics
Enzo Ferrari famously said “Aerodynamics are for people that can’t build engines”. But in today’s efficiency driven world, aerodynamics is one of the most important development areas for OEM’s. New regulations demand vehicles to maximise fuel economy and minimise emissions, leading engineers to design aerodynamically efficient cars.

The new release also includes updates for all of HELYX’s add-on solver modules, namely: Adjoint, Coupled, Marine and Hydro. HELYX 3.3.2 is mainly focused […]
How to Simulate the Piston Effect in Train Tunnels
Why do you have to yawn or swallow to equalize the pressure in your ears when travelling through a tunnel? It’s all to do with a phenomena called the piston effect. What is the piston effect? When a train enters a tunnel, it compresses the air ahead of it, as the air it displaces is […]
