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 Because design trends change so rapidly, a lengthy development cycle may produce outdated products.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.

Revealing the True Face of Titan With Physical Simulation

Space travel to Titan, 1.35 billion kilometers from Earth, is now possible — through simulation. Using data from the Huygens probe and Cassini spacecraft flybys, scientists simulated the surface of Saturn’s largest moon with the help of ANSYS SPEOS optical software. They created 360-degree visualizations from a virtual visitor’s point of view. This white paper describes their data-to-photorealism translation process.

Die Fluent Mosaic-Technologie von ANSYS verknüpft automatisch unterschiedliche Netze mit Polyeder-Elementen – zugunsten einer schnellen und genauen Strömungsauflösung

Der Übergang zwischen unterschiedlichen Typen von Netzelementen in komplexen Geometrien und Strömungsregionen bedeutete lange Zeit eine große Herausforderung für Simulationen. Die Mosaic-Technologie von ANSYS stellt sich dieser Herausforderung, indem unterschiedliche Netztypen mit allgemeinen Polyeder-Elementen automatisch verknüpft werden. Poly-Hexcore, die erste Anwendung der Mosaic-Technologie, füllt den Hauptbereich mit Octree-Hex-Netzen, behält in der Grenzschicht ein hochqualitatives mehrschichtiges Poly-Prismen-Netz bei und verbindet diese beiden Netze durchgehend mit allgemeinen Polyeder-Elementen. Die resultierende Simulation ist schneller – bei höherer Lösungsgenauigkeit und weniger RAM-Bedarf.

La technologie Fluent Mosaic d’ANSYS combine automatiquement des mailles disparates avec des éléments polyédriques pour une résolution de débit rapide et précise.

La transition entre différents types d'éléments maillés dans des géométries complexes et des schémas de flux a longtemps constitué un défi majeur pour la simulation. La technologie ANSYS Mosaic relève ce défi en connectant automatiquement différents types de maillages avec des éléments polyédriques généraux. Poly-Hexcore, la première application de la technologie Mosaic, remplit la région en vrac avec des hexagones octrés, maintient un maillage poly-prismatique en couches de haute qualité dans la couche limite et connecte de manière conforme ces deux maillages aux éléments polyédriques généraux. La simulation qui en résulte est plus rapide avec une plus grande précision de la solution tout en utilisant moins de RAM.

La tecnologia Mosaic di ANSYS Fluent combina in modo automatico le mesh più disparate con elementi poliedrici per una risoluzione del flusso rapida e precisa

La transizione tra varie tipologie di elementi di mesh per geometrie e regimi di flusso complessi rappresenta da tempo una grande sfida per la simulazione. La tecnologia Mosaic di ANSYS raccoglie tale sfida collegando automaticamente diversi tipi di mesh con elementi poliedrici generici. Poly-Hexcore, la prima applicazione della tecnologia Mosaic, riempie la maggior parte del volume con esagoni octree, mantiene strati di prismi di alta qualità nello strato limite e collega conformemente le due mesh tramite elementi poliedrici generici. La simulazione che ne risulta è più veloce e vanta una maggiore accuratezza di soluzione, utilizzando meno RAM.
