The examples of e-mobility and autonomous driving in particular demonstrate the need to be able to drive forward mechanical design, electronic design, software development and simulation in a holistically integrated manner and without system boundaries. Ansys is setting ambitious standards here with its new 2021 R1 version.
With simplified workflows and a modular system of product extensions that can be combined to suit the task at hand, Ansys 2021 R1 enables engineers to tackle design and product development goals in a way that was previously unattainable. The new version includes enhancements for large electromagnetic system simulations, which can also incorporate predefined components from different manufacturers with greater efficiency and scalability.

The software also offers support in the development of semiconductors, for example through comprehensive analysis of signal integrity, power integrity and the thermal and mechanical stress of 3D multi-die systems. In conjunction with Ansys Cloud, the enhancements ensure faster simulations, simpler workflows and additional solver functions. Simulation becomes accessible to companies of all sizes thanks to cloud-based software usage models. Users can quickly scale up to their specific needs in the areas of fluids, structures and electronics in order to solve calculation problems. "This capability," says Benjamin Turner, Mechanical Engineer at Hargrove Engineers + Constructors, "eliminates the need to install any software locally. I can also use my smartphone to check the status of my simulation."
Use in EV and AV development
With the development of autonomous vehicles (AV) and electric vehicles (EV) currently progressing ever faster, safety is a top priority. 2021 R1 offers special support here with its comprehensive sensor solution for AVs, which includes physics-based real-time radar sensor technology combined with closed-loop simulation validation to improve AV safety. New scanning and rotational lidar models also increase the reliability of AV simulation. In addition, the new solutions for embedded systems and software improve communication between team members and reduce the cost of certification. This leads to improved flexibility in modeling and code generation for automotive AUTOSAR software components and provides support for the FACE 3.0 technical standard for military avionics. In addition, the advanced system safety solution helps to improve EV and AV safety analysis by graphically showing where potential system failures can occur. This significantly simplifies the software safety testing process.
"By using medini analyze for software safety analysis (SSA), Bosch can reduce the effort required for SSA," says Sven Bergmann, Project Safety Manager, Robert Bosch GmbH. "This enables the reusability of information in an integrated tool, improves the acceptance of software architects and facilitates verification."
The new version makes the holistic development of EV components a reality. For example, a new battery design tool helps engineers optimize material selection for next-generation battery development, while a new EV powertrain library accelerates system simulation of electrified components. New software enhancements help add alert tones to advanced driver assistance systems that improve EV driving safety. New battery models enable engineers to tackle different scenarios, including battery crush, cooling, nail tests and module crush.
Ever shorter product development
Growing customer demands and ever-shorter product development timelines are presenting engineering teams with an unprecedented number of new challenges - from system-level problems to fundamental physics at the component level. Following the acquisition of Analytical Graphics, Inc., Ansys now also offers a comprehensive solution that can address all of this - from the component level to full mission-driven simulation.
2021 R1 also pushes the boundaries at the detailed physical level, enabling teams to make smarter decisions earlier in the product development process and avoid costly mistakes that can negatively impact product quality and reliability.
Two individual components of the current system are particularly noteworthy:
- Ansys Minerva facilitates the collaboration of flexible engineering teams through the latest advances in the simulation process and data management. Improved workflows not only serve experienced users, but also help inexperienced engineers to quickly learn how to use this software.
- Ansys Discovery, for example, provides automated liquid-solid thermal analysis for the design and evaluation of electronic cooling and thermal management devices. Qualup SAS uses this tool to visualize thermal and cooling design variants for the development of its 3D printers.

"It allows us to quickly evaluate the impact of different designs on the internal ventilation of the pressure chamber and the influence of the design on the cooling of certain components," says Philippe Boichut, owner of Qualup SAS. "The tool gives us the opportunity to change the modeling live and see the effects immediately."-dir/vti-
