Charged Up: A Holistic Approach to Developing Large-Scale Battery Management Systems
Behind every large-scale battery is an intelligent battery management system (BMS) that operates as a control center, balancing electrical input and output among cells, monitoring conditions, sending alerts when problems arise and, in a worst-case scenario, physically disconnecting the battery. This white paper describes the use of Ansys solutions for battery management, including physics-based simulation solutions to develop a system-level view of the battery using Ansys Twin Builder, Ansys medini analyze for safety analysis and Ansys SCADE for embedded software development.
GEKO – A New Paradigm in Turbulence Modeling
Since no single turbulence model is suitable for all flow applications, users must choose from a finite set of fixed models, hoping one fits their simulation. This white paper introduces GEKO (generalized k-ω), a revolutionary concept in turbulence modeling that gives you the flexibility to tailor turbulence models to your applications. Developed by turbulence expert Dr. Florian Menter, GEKO provides several free, tunable parameters, which can be adjusted over a wide range to match the simulation to specific physical effects, while maintaining the underlying calibration for flat plates and mixing layers.
Ansys Autonomy: A Foundation for NCAP Leadership
As passenger automobiles become more digitalized and more autonomous, they require a wide range of advanced technologies ― including sensors, such as cameras, radar and lidars, as well as embedded software supporting automated control systems. As artificial intelligence (AI) and machine learning (ML) become ubiquitous ― and mandatory ― the need for advanced technology will only increase. By mid-2022, many countries in Europe and Asia will require the addition of advanced emergency braking (AEB) systems, intelligent speed assistance (ISA) and other safety features.
Developing Critical Applications for Multicore Environments: The SCADE Advantage
Multicore environments that feature clusters of microprocessors deliver a range of benefits, but they present a significant challenge to the engineers who design embedded software for automotive, aerospace and other mission-critical applications. Ansys SCADE produces embedded software that enables the entire electronics architecture to perform reliably and all components to work together flawlessly, while accounting for the way essential tasks are distributed across multiple cores, how they communicate and how they are synchronized.
Integrating Product Development with Safety Analyses: A Value-Added Approach
Working in partnership, ANSYS and Jama Software have created a solution to help companies design game-changing electronics that meet the most stringent safety requirements. Leveraging the strengths of both companies, this solution includes a powerful tool set for managing the complex activities of product development, quality and reliability assessment and functional safety analysis.
How to get top IIHS safety pick status
Since 2016, IIHS (Insurance Institute for Highway Safety) has been testing headlamps with newly established methods. The IIHS test is performed on real equipment when the vehicle is ready to go, sometimes resulting in an unsatisfying rating. The result of the IIHS test has a strong influence on the market and on consumers, but automotive OEM companies and tier-1 suppliers don’t have the tools to make sure their future headlamps will meet IIHS requirements. What they need is to predict a poor rating during the early development phase of the headlamps, so that they have plenty of time to fix potential issues earlier and increase the safety and hence the very value of their car. The vehicle would then be highly competitive thanks to its improved safety and would contribute to reducing the number of fatal car accidents. The answer to this challenge, a fully-automated IIHS headlamp test simulation solution, including all vehicle dynamics, now enables OEM companies and Tier-1 suppliers to precisely predict the result of the IIHS headlamp test and to make the relevant design and performance optimization.
5 Best Practices for Gas Turbine Combustion Meshing Using Ansys Fluent
Combustors are complex geometries that have detailed features including fuel atomizers, swirlers, effusion and dilution orifices. Because of the complex nature of the combustor, the meshing process can result in long turnaround times and high costs. Ansys Fluent accelerates the meshing of large, complex geometries, like those of combustors, giving users complete control to generate a high-quality mesh that will yield robust, accurate results. This paper discusses the five best practices for meshing gas turbine combustion processes using Ansys Fluent’s patent pending mosaic meshing, which produces a hexahedral dominant mesh in the core and mosaic polyhedral cells that extend to the inflation layers of the wall. These best practices involve: 1. Watertight Geometry Workflow 2. Mosaic Poly-Hexcore Meshing with Parallel Scalability 3. Inflation Layers 4. Mesh Resolution Per Part 5. Target quality metrics
Amplifying the Benefits of Acoustic Simulation
The sound of a product will directly affect the user experience, making acoustic engineering a hot topic ― especially for transportation and consumer goods companies. Sound can be pleasant or unpleasant, a product benefit or an annoyance. It can also create a strong emotion and reinforce the brand identity of a product. But it can be difficult to quantify and predict the quality of a product’s sound in advance. Today, Ansys VRXPERIENCE Sound offers designers the powerful capability to listen to a simulation of their products’ sounds, based on a virtual prototype.
Ansys SCADE: Accelerating the Development of Automated Driving Technologies
Ansys SCADE software solutions support an efficient, model-based process for designing and verifying software at the very earliest stages of automated driving development.
All You Need to Know About Hardware for Simulation
Engineering simulation needs all the computer power it can get — and more. FEA and CFD users have complex problems with millions of elements, and generative design — built on simulation — will run simulations many times for each of the thousand solutions it generates. Most engineers are still trying to do all this on ageing workstations. What should you look for in a new workstation? We examine processors, CPUs and GPUs, memory and the latest storage technology. But will even the fastest workstation be enough? Many users find high-performance computing (HPC) to be the next logical step after exhausting the capabilities of workstations. HPC provides surprisingly quick solutions, allowing users to do more simulation iterations as well as more complex simulations. This report discusses introductory level HPCs and what you can expect. We also researched getting HPC as a service, which allows users to draw from an almost limitless amount of computer power that is not only affordable by consultants and small firms, but is also as easy to access as signing up for an account. In this report, we examine the options available for engineering hardware for simulation: The state of the art in engineering workstations. When do you need to jump to HPC? How much faster is HPC over workstations? What to look for in HPC hardware. Affordability of HPC. Is it better to rent HPC when you need it?
Ansys 5G Antenna Solutions
Designing 5G wireless systems is a huge undertaking. Antenna beamforming and beamsteering in 5G are key to improve the capacity and data rates for wireless applications. Massive MIMO, for instance, requires phased array antennas to be designed carefully to optimize the gain and ensure targeted coverage. Ansys tools are ideal for designing and simulating antennas, antenna-to-antenna coupling and environmental effects on signal propagation. Ansys solutions can enable successful deployment of V2X and V2V systems to improve the safety of self-driving cars that are expected to hit the road in 5G. Read this whitepaper to learn more.
