One of the biggest challenges in predicting fatigue failure is characterizing the load over the lifetime of a part. Using simulation solutions, like ANSYS Mechanical and ANSYS nCode DesignLife, engineers can run numerous load and design variations to ensure their products meet fatigue specifications and will continue to perform beyond the warranty period. Better yet, they can perform simulations and optimizations before building the product. In this way, engineers can make improvements early in the development cycle and utilize optimization algorithms to further streamline the design process. In this webinar, participants will learn the difference between material fatigue and high- and low-cycle fatigue failure, plus how to account for fatigue in design using simulation.

Ansys Fluent has been enhanced to organize the process for running simulations with a task-based workflow that guides you through the simulation process, reduces the options to only those that are relevant at each point in the process and provides best practices as defaults. This workflow presents you with the right choices to lead you to an accurate solution, making it possible to develop a better product in less time. Read this white paper to see how the new workflow can be can be utilized to reduce the time and software skill required to mesh watertight CAD geometry.
This paper describes the utilization of ANSYS HFSS with the novel HFSS SBR+ solver to analyze, predict and optimize radar signatures of electrically large targets and scenes. Subject models include targets such as aircraft, missiles, rockets and ships. In addition, the paper describes how electromagnetic simulations with ANSYS HFSS also provide deep field-level insight into electromagnetic interactions that contribute to radar scattering.
A large number of departmental workgroups run engineering simulation software on desk-side workstations. Popular software for such simulations include the mechanical suite of applications and Computational Fluid Dynamics codes Fluent and CFX from ANSYS which benefit from parallel processing. Although workstations are powerful machines that provide some parallel processing capability and large memory footprint they are ultimately limited in the number of processor cores, memory and IO performance providing an upper boundry to the capacity and capability of the simulation platform available to the engineers. Additionally, a workstation running engineering simulations will consume all available CPU and memory resources and therefore cannot be used for any other day-to-day tasks until the simulation has completed.
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.
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.
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.
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.
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.
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.
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
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 software solutions support an efficient, model-based process for designing and verifying software at the very earliest stages of automated driving development.
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?
