Read any automotive-related article and I’m sure it discusses autonomous cars and Advanced Driver Assistance Systems (ADAS) – the benefits, the challenges and what the future may hold. More and more auto makers are moving towards autonomous developing vehicles, but many of the systems that will eventually be integrated into these vehicles to make them fully autonomous are being developed today. In fact, you probably have some of them in the car you are driving now — Collision Mitigation Braking, Lane Departure Warning, Blind Spot Warning, and Lane Keeping Assistance to name a few. These ADAS applications present a new set of challenges and require a multi-disciplinary development approach. You can read more about these development areas in a blog written by my colleague, Sandeep Sovani.
About a year ago, my colleague, Eric Bantegnie, wrote a blog that described how we, along with our partners PTC, NI and HPE, had created a digital twin of a pump and one of its valves. We showcased this at PTC LiveWorx. I’m happy to announce that work continues with our partners on a new and expanded version of the digital twin of this pump and its valves to its motor and electric drive.
Why is this exciting and important? This enhanced digital twin demonstrates a multi-domain system including fluids, electromechanical, electromagnetics and thermal aspects, coupled with a user friendly Human Machine Interface (HMI), to solve a challenging problem that faces motor designers and operators — determining, monitoring and maintaining the optimal temperature at which to operate the motor and its components on a consistent basis. Why does this matter? Every 10 degree Celsius increase in operating temperature of the motor and components over their optimum temperatures decreases the life of the motor by half! Continue reading
The first issue of ANSYS Advantage for 2017 focuses on a revolutionary disruptive technology that you may just be starting to hear about: the digital twin. At the most basic level, a digital twin is a 3-D digital model of an operating physical system. The physical system can be a jet engine, a power generator, a pipeline, a locomotive or an entire industrial plant. Someday, you will most likely have your own digital twin — a virtual copy of yourself — that will allow you and your doctor to predict the behavior of your body to fine tune treatments and optimize your health.
Today’s automotive systems are more complex, smarter and more autonomous than ever before, featuring functionality that no one could have imagined 10 years ago. Advanced sensors and electronics control everything from a vehicle’s speed and position to its entertainment and communications technologies. Radar, cameras and other sophisticated electronics are increasingly being incorporated into consumer vehicles.
In fact, today, more than 60 percent of a car’s cost comes from its advanced electronics and software systems. Since many of the functions guided by electronic systems are mission-critical, it’s essential that all automotive systems work together with complete reliability. The tens of millions of lines of software code that control these systems must be flawless. Continue reading
Rather than just listing all the new capabilities for system simulation and analysis in the latest release of ANSYS Simplorer, I thought it would be interesting to share a cool example of how our systems capabilities have been applied to health monitoring of an automotive braking system. And along the way, I’ll highlight how the advancements in ANSYS 18 help our customers model and simulate systems such as these.
This example illustrates a physics-based system model intended to support health monitoring and predictive maintenance of automotive braking systems. And while this is an automotive example, our customers throughout different industries are developing similar capabilities to monitor and manage the performance of their products in operation — all in the name of improving safety, performance, and overall customer satisfaction.

I’m excited and honored to share with you the innovations in the latest release of our suite of simulation solutions, ANSYS 18, on behalf of over a thousand R&D professionals at ANSYS. The driving force for these innovations is the spread of simulation to all areas of engineering practice, a trend we call “pervasive engineering simulation.”
This trend is enabling engineers to explore the design parameter space earlier in the product lifecycle (digital exploration), test thousands of detailed designs rapidly and efficiently (digital prototyping), and monitor and optimize their product’s operation after it has been deployed (using digital twins).
To make pervasive engineering simulation as easy as possible for all engineers, we’ve added a lot of new features to each product family, as you can see below. For more information on ANSYS 18, including demo videos, webcasts, application briefs and technical papers, see our ANSYS 18 web pages. Continue reading
For over 30 years, ANSYS has been supplying GE with sophisticated first principle modeling tools that have enabled virtual prototyping of some of the worlds most complex products. The relationship continues to mature as the two explore the marriage of GE’s Predix Platform with ANSYS’ Simulation Platform to create the potential to enhance the monetization of asset health monitoring and the industrial internet of things. This marriage further enables closed loop feedback with engineering to accelerate NPI and drive costly warranty costs out.
The ANSYS Simulation Platform utilizes a variety of parameters sensed, collected and sorted by the Predix Platform, parameters such as temperature, pressure and vibration to create a simulation based physics model that represents a digital twin of an asset that can be used to accurately predict asset health.

A number of new and exciting workflow enhancements were included in ANSYS SCADE 17.2 for those who are validating and testing embedded software. In this blog, I’ll cover the top 3 enhancements.
Virtual System Testing Using Simplorer Entry
In ANSYS 17.2, all SCADE Suite users can immediately simulate and analyze virtual system prototypes thanks to the bundling of Simplorer Entry.
One of the main objectives of embedded software users is to perform closed-loop testing to tune the software application — as early as possible. As a best practice, embedding the application within a virtual environment is a great way to reduce testing costs. It can be performed first with simplified model of the environment using Modelica language then moved to high-fidelity models. Continue reading
Read any industry publication today and the Internet of Things (IoT) is a hot topic.Talk about how products will be connected to each other and interact with users on different levels is everywhere. But is all of this really possible? Will we see this type of connectivity and interaction any time soon? Gartner, the technology research company, says that there will be 6.4 billion connected devices this year, and many of these will be in the industrial sector. What advantage does this connectivity bring — digital twins, predictive maintenance and predictive analytics. Continue reading
Developing an Internet of Things (IoT) enabled product is a complicated task, whether it’s an autonomous vehicle, a vehicle user interface like a car infotainment system, or a connected factory. IoT-enabled products contain hundreds, if not millions, of lines of embedded software code. And many of these products — and the systems and software that control them — are mission- or safety-critical. Therefore, developers must have confidence that the software code controlling these devices is 100% accurate and responds in the intended manner. Continue reading
