A Common Simulation Language

With overnight aerodynamic simulations, engineers can drive performance improvements without sacrificing design styling. By reviewing studio innovations daily, engineers can explain how a design shapes air flow and designers are able to resolve issues on time and with style.

Royal Enfield discuss the deployment of the Altair HyperWorks Unlimited Appliance. The appliance is available on-premises or cloud-based to accelerate vehicle development programs through elevated CAE throughput or tactical cloud bursting.

Cloud Bursting Boosts Vehicle Development Programs

On-demand, high-performance computing (HPC) presents the opportunity to securely scale simulation capabilities during peak demand, satisfying the need for detailed, multi-disciplinary optimization studies on multiple programs to reduce development costs and risk.

The future of product development is where data analytics, simulation, and high-performance computing converge.

Accelerate Product Development

Create robust architectures during pre-program: The Altair Concept 1-2-3 (C123) design process enables designers to confidently create innovative, next-generation architectures by using simulation to inform vehicle architecture, manufacturing processes, material selection, and platform strategies.

Leverage high-performance computing: OEMs and suppliers rely on HPC for a faster time-to-market and superior product quality. Altair® PBS Works™ is a comprehensive workload management suite for clusters, supercomputers, and the cloud. Altair® Access™ lets you remotely visualize and interact with your data and applications, even across networks with challenging latencies.

Drive even more design with simulation: Altair’s next generation HyperWorks experience was created to enable your team to move from physics to physics, domain to domain, and even create reports without ever leaving the model. Every tool in the suite delivers a solution-specific workflow with a meticulously designed and discoverable user-interface.

A Safer, More Comfortable Driving Experience

Increase passenger protection: In the age of autonomy and car sharing, new seating positions demand a fresh investigation of passenger safety using Altair® Radioss®, an industry standard for automotive crash, impact, and airbag simulations. Altair® MotionSolve® helps chassis systems achieve vehicle dynamics targets and ensure safe maneuverability. With Altair® Feko®, vehicle connectivity and electromagnetic compatibility (EMC), which are essential to today’s vehicles, can be verified.

Improve quality and design performance: Customers expect better vehicle performance, including minimizing noise, vibration, and harshness (NVH), and the annoying squeak and rattle (S&R) phenomena. Altair® HyperWorks® offers a broad range of functionality for CAE engineers and analysts, reducing the full-vehicle NVH simulation time, freeing up time to optimize product design and performance. Altair® Squeak and Rattle Director™ identifies and analyzes design alternatives to eliminate S&R causes.

Create the optimal environment: In the past, engineers relied on wind tunnel tests during the design cycle to determine the effectiveness of heating, ventilation, and air conditioning (HVAC) systems. Altair CFD™ helps make more informed decisions earlier in the design cycle. Using transient computational fluid dynamics (CFD) simulation, it accurately models the air flow through the HVAC system, ensuring safer windshield defrosting capability, while optimizing the thermal management of electrical and mechatronic systems.

More Autonomous and ADAS

Improved Fuel Efficiency and Durability

Better tools for fuel efficiency: Automakers need a multipronged approach to achieve fuel efficiency, lighter structures, and aerodynamics performance. Altair® OptiStruct® helps designers and engineers do just that, all while reducing costs and maintaining performance. Altair CFD improves external aerodynamic performance by applying GPU hardware to speed their decision making.

Durability for fleet or personal use: Future fleets of autonomous vehicles will cover more miles than personal cars for economic reasons: to cover the cost of expensive hardware and increase profitability by driving longer than a human would. Altair® HyperLife® provides a comprehensive toolset for durability analysis to enable the prediction of fatigue life under the repetitive loadings of a vehicle life. Vehicle durability loads can be extracted from MotionSolve.

Accelerate powertrain electrification: The move towards hybrid and full-electric powertrain systems delivers both business challenges and opportunities. Bringing BEV development cycles into alignment with traditional timelines require changes to engineering team structures and toolsets. Powertrains must be highly efficient and lightweight while meeting new regulations and growing customer expectations.

Antennas, Wireless Connectivity, and EMC Performance

The use of electromagnetic waves in automobiles continues to expand. What started with radio and television broadcasting has now expanded to remote keyless entry systems, tire pressure monitoring systems (TPMS), wireless communications, advanced driver assistant systems (ADAS), and more, making consideration of electromagnetic compatibility indispensable.

Feko, a complete toolset of high-frequency electromagnetic field simulation software that integrates Altair's wide variety of analysis methods, is the solution for analyzing and designing antennas, wireless connectivity, and EMC problems chosen by a wide range of OEMs and suppliers in the automotive industry.

Fully Automated Optimization Engine

ZF develops a wide variety of e-motors and e-drives for a broad spectrum of automotive customers. To optimally incorporate development and production costs from the outset, their designers must find solutions to maximize shared parts within the given requirements for the motors. To achieve this, ZF groups products into motor programs that have similar design and production objectives and identifies common design features that can be used across a modular motor platform. However, the potential scope of motor configurations is enormously extensive. With a theoretically infinite number of motor configuration possibilities, it would be impossible with human resources to manually select an optimal combination of motor configurations for a motor platform while accounting for all requirements. Consequently, ZF needed a simulation and data-driven solution that would empower them to consider shared parts, costs, and further constraints to automatically find best configurations for a modular motor platform.
