With the launch of Ansys 2021 R2 Software Updates, significant upgrades have been made to Ansys’ next-generation engineering software, High-performance Computing (HPC) resources, and platform solutions to power team-wide global collaboration and information sharing.

Ansys 2021 R2 Upgrades | Introduction

Engineering teams are facing more demanding challenges than ever before. Teams are tasked with solving complex designs and meeting demanding product development schedules, all while working remotely due to COVID-19 precautions.

Ansys 2021 R2 helps engineering teams accelerate innovation in any environment and creates cutting-edge designs by harnessing new workflows and dynamic capabilities across Ansys’ flagship suites.

New Ansys R2 Cloud™ Enhancmenets

Updates in Ansys® Cloud™ offerings, such as virtual desktop infrastructure support, unites Ansys’ flagship simulation solutions with highly scalable compute power delivered by cloud-based HPC.

Platform solutions enhanced with powerful workflows deliver a streamlined user experience with enhanced functionality for data and configuration management, dependencies visualization and decision support, as well as user-friendly workflows for process integration and design optimization, and materials management.

Ansys Digital Twin Technology | Predictive Maintenance Upgrades

Ansys’ digital twin solutions enable remote monitoring of assets and are a critical component for predictive maintenance.

Collectively, these resources will help users generate larger, more complex designs easier and faster than ever, increase productivity, spur development of high-quality products and expedite time to market.

Ansys Updates Relating to Regulatory Provisions | Safety of the Intended Functionality (SOTIF)

Ansys 2021 R2 Software Updates improves deployment, scalability, and performance of AI-based perception software testing through multi-GPU parallelization, making it easy to systematically identify hazards and comply with new safety standards like Safety of the Intended Functionality (SOTIF).

In support of automotive electrification, a new thermal and vibrational analysis coupled with Ansys’ electromagnetic field simulation software will help predict reliability and noise, vibration and harshness. Additionally, modeling thermal behavior of batteries during all stages of the design cycle has been made easier by using a streamlined workflow and new capabilities that simulate the important effects of capacity fade and cell life.
