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 Mentor, 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.

Simulation in the Cloud: The new imperative

ANSYS Cloud is a cloud service fully managed by ANSYS and developed in collaboration with Microsoft Azure that provides on-demand access to HPC directly from within ANSYS flagship applications. It allows engineers to access the powerful capabilities of the world’s leading simulation software, without investing in on-premise hardware, processors and multiple software licenses. Instead of waiting in line for scarce computing resources, engineers can capitalize on the elastic capabilities of ANSYS Cloud to run simulations — even numerically large simulations ¬— whenever and wherever they want. Architected for security following Microsoft’s security best practices, it meets the highest security protocols, while still offering ease of sharing simulation results — leading to a significant competitive advantage.

SMART Fracture

With the new Unstructured Mesh Method (UMM) in ANSYS Mechanical, engineers can reduce preprocessing time by employing UMM’s automatically generated all-tetrahedral (tet) mesh for crack fronts, while achieving the same high-fidelity results as a simulation run with the ideal hex mesh configuration. Meshing time has been reduced from up to several days to a few minutes.
Using UMM, ANSYS has also introduced the Separating Morphing and Adaptive Remeshing Technology (SMART) crack growth simulation technology to ANSYS Mechanical to enable automatic remeshing during a simulation. A SMART simulation can be set up with several clicks, eliminating long preprocessing sessions.

An Integrated Simulation Platform to Validate Autonomous Vehicle Safety

Autonomous driving systems rely upon sensors and embedded software for localization, perception, motion planning and execution. Autonomous driving systems can only be released to the public after developers have demonstrated their ability to achieve extremely high levels of safety. Today’s hands-off autonomous driving systems are largely built with deep learning algorithms that can be trained to make the right decision for nearly every driving situation. These systems, however, lack the detailed requirements and architecture that have been used up to now to validate safety-critical software, such as that which controls commercial airliners. Road testing is clearly an essential part of the development process, but billions of miles of road testing would be required to validate the safety of autonomous driving systems and software. Simulation is needed to make verification and validation of the operation of autonomous vehicles a practical endeavor.

Managing Changing Quality Needs in Automotive and Consumer Product Industries

As user experience and shared brand or product perceptions effectively dictate purchasing decisions, exceeding customers’ expectations in a cost-effective manner is an imperative for manufacturers. Because design trends change so rapidly, a lengthy development cycle may produce outdated products. To optimize time to market, product stakeholders must improve their efficiency in both product and process design to deliver first-time-right products. New sophisticated quality and visualization tools can help predict manufacturing variation and its impact on perceived quality at an earlier stage, when issues can be addressed with minimal cost. In this white paper, discover how preliminary quality assessment is becoming a must-have in current design processes — for a more streamlined product development lifecycle, with a shortened lead time from concept to production.

How to Design, Optimize and Validate Safe Laser Headlamps Through Virtual Experimentation

Today, car manufacturers and their suppliers are facing a real challenge: designing attractive laser headlamps that will illuminate the road without blinding drivers and pedestrians. Validating the safety of these headlight systems using physical prototypes would require millions of miles of night-driving testing and cost-prohibitive investment.

Simulation is the only option for adequately assessing how a headlight design will perform under numerous road, weather, lighting conditions. Engineers can perform virtual tests in greater numbers and at faster speeds, while reducing development time and prototyping costs.

Is Physics-based Virtual Prototyping the Future of Automotive Interior Lighting Validation?

Physics-based virtual prototyping allows car interior designers to predict potential lighting issues — and avoid them. Accounting for the interaction between light, materials and human perception early in the development process eliminates costly design fixes downstream.

Towards Smarter Aircraft Interfaces With Virtual Reality

This white paper explores the i-VISION project, which partners academia, aerospace and ANSYS to develop virtual reality technologies to accelerate the design of “human-centered” aircraft cockpits. These technologies are also applicable to other transportation industries that face the same issues and questions related to cabin design and the interaction between the cabin interface, environmental conditions and human operator.
