Simulating Conjugate Heat Transfer in CFD
In thermal simulations, most real world cases involve the transfer of heat between different states of matter, such as from solid to liquid. This is known as Conjugate Heat Transfer (CHT). Understanding the complex thermal interactions between these states allows us to enhance the thermal performance of electronics, engines, heat exchangers and much more. However, […]
Harnessing The Power Of AI In CFD Analysis
Artificial Intelligence (AI) has exploded into almost every industry over the last few years and is expected to grow from $86.9 billion in revenue in 2022 to over $407 billion by 2027 [1]. This extraordinary growth may feel like it has sneaked up on us, but the machine learning modelling techniques that lie at the […]
The Continuous Adjoint Method For Optimization Problems
Aerodynamics is a discipline filled with optimization problems. Whether it is drag, lift or downforce, an aerodynamicists’ goal is to maximise the potential performance of an object within a set of constraints. To achieve this, the typical approach is to change an input variable and analyse the effect on the output. However, a more efficient […]
How CFD Bridges The Gap Between Car Design And Aerodynamics
The typical range of a fully charged Electric Vehicle (EV) is approximately 100 to 300 miles (161 to 483 kilometres) [1]. To increase this range further whilst minimising the number of charging stops during a journey, manufacturers are exploiting every opportunity to improve efficiency. Whether it is the powertrain, weight or aerodynamics, the more efficient […]
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, […]
Creating a Bespoke CFD Simulation Template for Koenigsegg
The automotive industry is currently enduring one of its most challenging periods to date. Manufacturers need to develop lighter, cheaper, more efficient vehicles whilst dealing with chip shortages, rising costs and the continued debate around powertrain technologies. This has demanded innovation and in 2020, €58.8 billion was invested in automotive R&D in Europe alone, 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.
