Robust Design Optimization Of A Ford Turbocharger Compressor
By Anne-Marie Schelkens - 02 Mar, 2023 - Comments: 0

What is robust design optimization (RDO), and is it better than standard optimization? In this customer case, we describe a multi-disciplinary optimization of a turbocharger compressor from Ford Motor Company, in which we demonstrate it is. RDO combines standard numerical optimization with sensitivity analysis to take into account the influence of manufacturing variations and operating uncer... » read more

Automotive Security Vulnerabilities From Afar
By Paul McLellan - 02 Feb, 2023 - Comments: 0

Don't confuse automotive security with automotive safety, things like functional safety (FuSa) and ISO 26262. You need security to have safety. But security is its own thing. In a modern connected car, there are two places for security vulnerabilities. One is in the car itself. And the other is back at base in the automotive manufacturer's (OEM in the jargon) data centers, which the cars are co... » read more

Software-Defined Vehicles: The Automotive Revolution With Silicon At Its Heart
By Ben Gu - 05 Jan, 2023 - Comments: 0

The automotive sector is undergoing immense change. The retirement of the internal combustion engine (ICE) in favor of electrified powertrains and a shift towards autonomy has provided carmakers the opportunity to reimagine and redefine the entire automotive experience: how a car looks, works, and behaves, from the tires up. But such change isn’t easy. An industry founded on the manufactur... » read more

Smart Manufacturing: What’s Needed For The Industrial Intelligence Revolution?
By Ben Gu - 01 Dec, 2022 - Comments: 0

Smart manufacturing – the use of nascent technology within the industrial Internet of things (IIoT) to address traditional manufacturing challenges – is leading a supply chain revolution, resulting in smart, connected, and intelligent environments, capable of self-operation and self-healing. While factory automation has been around for decades, smart manufacturing goes a great deal furth... » read more

RISC-V Is Thriving: Here’s What You Need to Know
By Steve Brown - 03 Nov, 2022 - Comments: 0

RISC-V, the open-standard Instruction Set Architecture (ISA) conceived by UC Berkeley developers in 2010, is going from strength to strength. The RISC in RISC-V stands for Reduced Instruction Set Computer, meaning it’s designed to simplify each individual instruction given to the computer. As RISC-V is an open standard, anyone can implement, customize, and expand the ISA to suit their r... » read more

Formula 1: Riding The Sustainability Wave To Full Electrification
By Steve Brown - 06 Oct, 2022 - Comments: 0

Ferdinand Porsche once said, "The perfect race car crosses the finish line 1st and then crumbles into its individual parts." What a take, right? Well, in the 90s, that's the best they could hope for. Let's go back to the 1990s of Formula 1 (F1). The time was marked by extreme competition among racing teams. There was more freedom in the engine you could run, meaning that teams could choose b... » read more

Structured Grids Are Here For An Eternity
By Veena Parthan - 01 Sep, 2022 - Comments: 0

With unstructured meshes delivering promising results in resolving boundary layers, wakes, and other flow features for complex geometries, one might arrive at the conclusion that structured grids will soon be out of the markets because of their reputation for taking a long time for generation. On the contrary, structured grids give you two things that unstructured meshes may lack, i.e., quality... » read more

AEK: Powerpoint Is Easy—Change is Hard
By Paul McLellan - 04 Aug, 2022 - Comments: 0

A major message to big-name automakers at the Automobil Elektronik Kongress 2022 was, "You old-time car guys don't get it. We have to deliver a smartphone experience in a vehicle. If not, we will be out of our jobs, and someone else will." CARIAD I thought that the most interesting presentation was by Riclef Schmidt-Clausen of CARIAD. CARIAD is a spinout from Volkswagen (VW) of their software... » read more

Mesh Generation And CFD For A Drone’s Coaxial Rotor
By John Chawner - 07 Jul, 2022 - Comments: 0

Our Cadence Channel Partner in Scandinavia, neptech, shares a case study investigating the interaction of a coaxial rotor system and how to optimize its efficiency. Coaxial rotor systems are appealing for multirotor drones, as they increase thrust without increasing the vehicle’s footprint. However, the thrust of a coaxial rotor system is reduced compared to having the rotors in line. It... » read more
