What is the Adjoint Method in CFD?
Every industry is trying to find new ways to improve performance, maximise productivity and increase efficiency. To achieve this, engineers, scientists and programmers are tasked with solving optimisation problems. The conventional way to optimise something in engineering is to change an input (typically a geometric parameter) and analyse its effect on the output (what we […]

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.
